Question

Bacteriorhodopsin is a membrane transport protein that uses sunlight to do

what?
A. Hydrolyze ATP molecules
B. Pump H+ out of the cell and generate a H+ gradient across the plasma
membrane
C. Pump photons into the cell and generate a deep purple color
D. Convert CO2 into sugar during photosynthesis

Answer 1

Bacteriorhodopsin is a membrane transport protein that uses sunlight to pump H+ out of the cell and generate a H+ gradient across the plasma membrane. This process is called chemiosmosis.

Step-by-step explanation:

Bacteriorhodopsin is a membrane transport protein that pumps H+ out of the cell and generates a H+ gradient across the plasma membrane using sunlight. Protons then flow back into the cell, down their electrochemical gradient, in a process associated with ATP formation. This process is called chemiosmosis.
