Q21) In my opinion, the case is the phosphorylation of the membrane protein by ATP which itself gets converted to ADP and the phosphorylation of the membrane proteins leads to conformational change in the protein.
hence option d is correct.
Q22) True.
Oxidation means loss of electron while as reduction means gain of electron.
Q23) and Q24) are not clear.
Q25) True
In cellular respiration, Glycolysis occurs in cytoplasm where substrate level phosphorylation leads to ATP production. Krebs cycle operates in Mitochondria where ATP are produced in mt. electron transport chain via oxidative phosphorylation
