What does the endocytoplasmic membrane do?
compartmentalize cytoplasm, allows different pHs in cell for different reaction and enzyme function.

New cards
Why are some molecules more permeable than others?
Some molecules = hydrophobic (non-polar), harder for aqueous solution to pass through.
3
New cards
What is an active membrane?
a membrane with more proteins
4
New cards
Role of aquaporins in the membrane
increasing permeability
(channel to pass polar water molecules)
