AP Biology Unit 2 Review (cell structure and function)

Which of the following cells contain the highest water potential?

• A

• B

• C

• D

If a student was going to draw an arrow indicating the solution from the highest water potential to the lowest water potential, the arrow would be pointing 

• from the left to the right
• from the right to the left

A protein that is destined for the membrane would be made 

• on a ribosome that is in the cytoplasm
• within a lysosome
• on a ribosome attached to the rough endoplasmic reticulum 
• within the Golgi body

In the membrane section seen, which section would represent the non-polar section of a protein?

• A
• B
• C
• D

Researchers inserted pieces of membrane with aquaporins into frog eggs and placed the eggs into a hypotonic solution.  What did they observe?

• The aquaporins started to pump out water
• The eggs started to pump out Na+ to draw out water
• The eggs started to swell rapidly as water diffused inside
• The aquaporins started to pump in water
