1. Large quantities of water can pass through special membrane proteins called ______________
   
   
   
2. Active transport uses carrier proteins called _______________ and help establish and maintain ___________________ ______________________

1. __________________  uses the energy from an electrochemical gradient to transport two different ions across the cell membrane.  If the two ions are transported in the same direction, it is called _______________, if the two ions are transported in opposite directions, it is called __________________

1. The movement of ions across the cell membrane may result in the creation of an ______________________________  gradient. This gradient results in a membrane potential or voltage across the membrane.

1. The sodium-potassium pump uses ATP to pump three ____________ ions out of the cell for every two __________________ ions it pumps into the cell.  This creates a __________________  ___________________.

1. If ADH secretion is inhibited, what would be the result?

Watch the short video animation & answer the 5 questions correctly and document below. To receive credit, all 5 questions must be correct. Do it again if you do not pass the first time. Continue until you have all 5 questions correct.

"As a veterinarian, students help a young calf, named Clark, who is having seizures. To determine the cause, the students fly into Clark's brain to learn about osmosis and apply their learning to save Clark".

Expect this STEM CASE to take 90 minutes to complete.

It is time to save Clark! This will open during class on Thursday.
