Exocytosis allows the particle to leave the cell membrane.]]> 2017-11-02 15:34:51 UTC https://padlet.com/tdrop23/vdvuvtwexspi/wish/202965491 aarnette23 https://padlet.com/tdrop23/vdvuvtwexspi/wish/202967199 The cell membrane is important because everything crosses through it. Even cells move in and out of the membrane]]> 2017-11-02 15:37:29 UTC https://padlet.com/tdrop23/vdvuvtwexspi/wish/202967199 nhasnain23 https://padlet.com/tdrop23/vdvuvtwexspi/wish/203715205 Active transport is the process of the cell using its energy to move materials through the cell membrane. This is unlike passive transport which does the same action but without using the cell's energy. The choice of which one the cell uses depends on if the materials are dissolved or if diffusion occurs. Dissolved materials require no energy usage from the cell because they are very easily movable through the membrane. However, if diffusion happens, then the cell must use energy to have them pass through. It's very similar to how you ride a bike. If you're going downhill, it takes little to no energy to pick up speed. But if you're going uphill, you have to use a lot more energy.]]> 2017-11-06 01:55:33 UTC https://padlet.com/tdrop23/vdvuvtwexspi/wish/203715205 tdrop23 https://padlet.com/tdrop23/vdvuvtwexspi/wish/203866410 With the cell moving things across its self is like you riding a bike down a hill. It doesn't take much power to go fast but if you want to get back up the hill you have to use energy. This is the same thing with cells. At sometimes the cell uses zero energy!   ]]> 2017-11-06 13:52:29 UTC https://padlet.com/tdrop23/vdvuvtwexspi/wish/203866410
