Active transport requires energy to be used from the cell

# data[].attributes.body
Active transport requires work and energy to pass through but passive does not

# data[].attributes.body
Active transport requires the cell to use energy to move a molecule in a certain direction. Passive transport does not require the cell to use energy.

# data[].attributes.body
Active transport requires energy while passive transport just uses diffusion/facilitated diffusion

# data[].attributes.body
Active transport uses energy to pass a molecule through and passive doesn't use energy.

# data[].attributes.body
Active transport is molecules going from low to high and requiring more energy while passive transport doesn't require much energy.

# data[].attributes.body
Passive transport doesn't require energy while active transport does.

# data[].attributes.body
passive transport doesn't require energy to transfer cells.

# data[].attributes.body
Active transport requires energy

# data[].attributes.body
Passive transport moves molecules from high to low concentration. It works as a channel to allow cells to go where they naturally want to go.
Active transport pushes larger molecules from low to high concentration (where they don't want to go) and uses energy.

# data[].attributes.body
Active transport is when cells are being moved up the concentration gradation and require energy to do so.Passive requires no energy because the molecules are only going down.

# data[].attributes.body
Active transport requires energy input by the cell while passive transport doesn't

# data[].attributes.body
Passive transport doesn't require energy but active transport does. In active transport the molecules move against the concentration gradient and in passive transport they move down the gradient.

# data[].attributes.body
Active transport requires energy, while passive does not. This is because active transport is moving the molecules from low to high concentration, while passive is moving the molecules from high to low.

# data[].attributes.body
Facilitated diffusion needs some sort of helper to allow cell to get through

# data[].attributes.body
Active transport uses energy while passive transport doesn't.

# data[].attributes.body
active transport is against cell gradient and goes from low to high

# data[].attributes.body
Active transport requires energy while passive does not

# data[].attributes.body
Facilitated diffusion needs help to let another cell enter through but simple diffusion doesn't need help.

# data[].attributes.body
Active transport requires energy to move molecules.

# data[].attributes.body
Facilitated diffusion is diffusion added by the protein strands to diffuse. This is helpful when a charged ion (Na/K) is diffusing but can't with the phospolipids.

# data[].attributes.body
facilitated diffusion involves a channel rather than a phospholipid.

# data[].attributes.body
Passive transport does not need energy from the cell, but active transport does.

# data[].attributes.body
Active requires energy where passive doesn't because t goes from high to low not low to high

# data[].attributes.body
Facilitated diffusion needs a molecule to help the other molecule pass while simple diffusion doesn't

# data[].attributes.body
In facilitated diffusion, molecules only move with the help of a protein in the membrane.

# data[].attributes.body
Passive transport does not require any energy, where as active transport requires the cell to use ATP to make specific substances move against the concentration gradient.

# data[].attributes.body
Simple diffusion doesn't need a helper to get through, but facilitated diffusion does.

# data[].attributes.body
Facilitated diffusion requires more steps and molecules

# data[].attributes.body
facilitated diffusion can move large molecules

# data[].attributes.body
Facilitated diffusion means that a molecule needs help to pass through the membrane.

# data[].attributes.body
A concentration gradient is wear their is a difference in the amount of molecules on each, these are the places were transportation of molecule active or passive happens

# data[].attributes.body
Facilitated diffusion requires help while in simple diffusion doesn't.

# data[].attributes.body
The molecules in simple diffusion pass between phospholipids and the molecules in facilitated diffusion move through protein channels or carrier proteins. Also, facilitated diffusion can move larger molecules as well as charged molecules.

# data[].attributes.body
Facilitated diffusion needs help to pass a cell through, while simple diffusion does not.

# data[].attributes.body
Facilitated uses channels or carriers where simple doesn't use channels

# data[].attributes.body
active transport requires cell to use energy and passive does not.

# data[].attributes.body
facilitated diffusion requires assistance to help molecules get through while simple diffusion doesn't require assistance.

# data[].attributes.body
Facilitated is for molecules that can not go through the cell with simple diffusion.

# data[].attributes.headline
Facilitated diffusion is transport through a gate that needs help from other proteins to get through because parts of the molecule are negative.. Simple diffusion does not need help because of the positive ions.

Facilitated diffusion is transport through a gate that needs help from other proteins to get through because parts of the molecule are negative.. Simple diffusion does not need help because of the positive ions. 

# data[].attributes.body
The concentration gradient is the direction that molecules like to move. When molecules move across the concentration gradient, they are moving from areas of high concentration to areas of low concentration.

# data[].attributes.body
The concentration gradient is describing the amount of molecules inside, and outside the cell. If the concentration is higher outside the cell, diffusion will take place.

# data[].attributes.body
Facilitated diffusion needs other things to help it happen, like channel proteins or carrier proteins, and simple diffusion just flows with the concentration gradient.

# data[].attributes.body
concentration gradient is the difference in concentration on the different sides of the membrane. it moves from high to low until equilibrium is reached.

# data[].attributes.body
Concentration gradient is where there is a difference of concentration on the other side of the membrane. Molecules move from somewhere with high concentration to low concentration.

# data[].attributes.body
Facilitated diffusion is using a channel and "lock and key" concept to allow the gate to open and molecules to pass through.
Simple diffusion is more random and doesn't move large molecules between the phospholipids.

# data[].attributes.body
The concentration gradient is the concentration of a molecule on either side of a membrane. Molecules often move "down" the membrane in which they move from an area of high concentration to low.

# data[].attributes.body
Simple diffusion moves the molecules through the phospholipids and facilitated diffusion uses hormones that bond to channels to move it through the membrane spanning proteins.

# data[].attributes.body
Concentration Gradient is the difference between the concentration of one side of the membrane to the other (high to low)

# data[].attributes.body
The concentration gradient is the concentration on each side of a membrane. Molecules move down or up the gradient to lower or higher levels of concntration

# data[].attributes.body
Facilitated diffusion always involves channel proteins and in simple diffusion, molecules pass through the phospholipids.

# data[].attributes.body
The concentration gradient is the difference between the number of cells in two different areas. Cells love to move from high to low, but they can use active transport to move from low to high.

# data[].attributes.body
A concentration gradient uses diffusion and creates equilibrium within the cells

# data[].attributes.body
It moves things from high to low and low to high

# data[].attributes.body
Concentration gradient allows the flow of molecules in one direction. It also helps make an equillibrium.

# data[].attributes.body
The concentration gradient is when there are different levels of concentration inside and outside of the cell. Simple and facilitated diffusion move down a concentration gradient and active transport moves up the gradient.

# data[].attributes.body
The concentration gradient is where the cells move to find equilibrium when there is an unequal balance

Concentration Gradient is when there are particles on different sides of the membrane. Particles more from high to low to get to equilibrium.

# data[].attributes.subject
Concentration Gradient is when there are particles on different sides of the membrane. Particles more from high to low to get to equilibrium.

# data[].attributes.body
The concentration gradient is when there are different amounts of certain molecules on the sides of the membrane and it causes the molecules to go from high to low until it reaches equilibrium

# data[].attributes.body
the concentration gradient is what particles move along until it reaches equilibrium.

# data[].attributes.body
The concentration gradient is the force of the pushing of substances in and out of the cell that attempts to reach equilibrium. The flow goes from areas of high concentration to low concentration. This requires active transport to expend energy due to its traveling against the gradient. This also means passive transport is controlled entirely by the gradient.

# data[].attributes.body
when there is a unbalance in of particles on either side of the membrane there is a concentration gradient. moves molecules from high to low until they are equal

# data[].attributes.body
The concentration gradient is where there is not an equal amount of molecules on either side of the cell. Molecules will move across the concentration gradient until there is an equilibrium.

# data[].attributes.body
The concentration gradient is when there is a difference of a particular particle on either side of the membrane. This is where particles move along from high to low concentration in transport

# data[].attributes.body
The concentration gradient is the direction by which the molecules move. Molecules move from high to low concentration until equilibrium is reached, which also causes the movement to become random and not direction-oriented anymore.
