What catalyzes the rate-limiting step of the Calvin Cycle?a. ribulose phosphate isomeraseb. RuBisCOc. phosphoglycerate kinased. PEP carboxylase
Chemiosmosis is a part of oxidative phosphorylation, the final step in cellular respiration. Which of the following is TRUE regarding chemiosmosis? ATP synthesis creates a proton gradient that causes electron flow through an electron transport chain (ETC). A temperature gradient drives ATP synthesis. The energy from a proton gradient is used to make ATP. Chemiosmosis regenerates electron carriers like NADH and FADH2.
Which of the following BEST describes the function of the electron transport system? Energy absorbed by the cytochromes in the system is converted to ATP. The system functions to produce ATP by chemiosmosis in the absence of oxygen. Energy lost from high-energy electrons causes the oxidation of glucose. Energy lost from high-energy electrons results in ATP production by chemiosmosis.
