What enzyme catalyzes ATP hydrolysis?
ATPase. Keywords: ATPase, enzyme.
Why are ATP phosphate bonds called “high energy”?
They contain electrons in a high-energy state, not because the bond is strong. Keywords: high-energy electrons, weak bond.
What provides energy to regenerate ATP?
Oxidation of glucose (and other substrates) in cellular respiration. Keywords: glucose oxidation.
Why is heat produced in respiration useful?
Maintains body temperature for optimal enzyme function. Keywords: thermoregulation, enzymes.
Distinguish ATP hydrolysis vs phosphorylation.
Hydrolysis: ATP → ADP + Pi (releases energy). Phosphorylation: ADP + Pi → ATP (requires energy). Keywords: ATP cycle, reversible.
