What is required for chemiosmosis to occur?
Options
- AOnly a membrane and a proton pump
- BOnly a proton gradient and ATP synthase
- CA membrane, a proton pump, a proton gradient, and ATP synthase
- DLight energy and chlorophyll
Correct answer
C. A membrane, a proton pump, a proton gradient, and ATP synthase
Step-by-step solution
Chemiosmosis requires a membrane, a proton pump, a proton gradient and ATP synthase. Energy is used to pump protons across a membrane, to create a gradient or a high concentration of protons within the thylakoid lumen. ATP synthase has a channel that allows diffusion of protons back across the membrane; this releases enough energy to activate ATP synthase enzyme that catalyses the formation of ATP
