Introduction The energy used and stored by cells is derived from adenosine triphosphate (ATP). Adenine, ribose sugar, and three serially bonded phosphate groups make up the nucleoside triphosphate (NTP) structure of ATP.Answer: Correct options are: ATP synthase is a transport protein. Explanation: when there is an electrochemical gradient of H+ established above and below the inner mitochondrial membrane, H+ ions are transported via ATP synthase from the matrix to intermembrane space ( Space between outer and inner membrane f mitochondria) and utilize the energy to synthesize ATP from ADP and Pi. So, we can say it is a transport protein. ATP synthase is an integral membrane protein Explanation: ATP synthase is located in the inner mitochondrial membrane. it has two subunits F0and F1. F0 is integral part of this protein and F1 is free facing intermembrane space. so we can say this is an integral protein. Incorrect options are: ATP synthase makes a total of four ATP molecules in glycolysis. Explanation: ATP produced during Glycolysis is the product of substrate-level Phosphorylation ( in a chemical reaction where the released phosphate group is taken up by ADP molecule to synthesize ATP) and there is no need of ATP synthase. Under aerobic conditions, the F1 portion of ATP synthase catalyzes a catabolic reaction. Explanation: ATP synthase catalyzes an anabolic reaction, ADP+Pi (inorganic phosphate)=ATP. ATP synthase relies on an electrochemical gradient of sodium ions to catalyze the formation of ATP. Explanation: It is H+ electrochemical gradient that catalyzes the formation of ATP, not Na+. ATP synthase is an important enzyme in the citric acid cycle. Explanation: though ATP synthase work like an enzyme that catalyzes the reaction ADP+Pi (inorganic phosphate)=ATP, ATP synthase comes into play to produce ATP utilizing electrons of NADH2 and FADH2 which are the produced either during glycolysis or citric acid cycle in Electron Transport Chain. it has no role in either glycolysis and citric acid cycle.
