How are channel and carrier proteins in the plasma membrane are similar?
Both allow for the flow of molecules into and out of a cell.
A protein which catalyzes (speeds up) a biochemical reaction
Enzyme
The process in which autotrophs convert light energy into chemical energy
Photosynthesis
What are two products of cell respiration
