Question 4 1 pts Which of the following compound can uncouple the process of proton gradient...
What supports the contention that proton gradient drives ATP formation in mitochondria? Explain the process of ATP synthesis?
Question 12 1 pts From your General Cell Biology knowledge, what biological process occurs in/on cristae? Glycolysis Calvin Cycle Cellular respiration TCA cycle DQuestion 13 1 pts From your General Cell Biology knowledge, what is cellular respiration? O The energy stored in the proton electrochemical gradient is harnessed by a proton channel that uses the energy released to turn the ATP synthase to power the synthesis of ATP. Glucose is metabolized to pyruvate with the formation of reduced intermediates, NADH,...
