Question

Biochemistry Q17 Which of the molecules below is not a substrate for substrate-level phosphorylations? (a) o (b) OH (c) HO OH OH OH OH HO I O OH o OH OH (e) OH P OH OH OH NH Which of the molecules above serves as pool for immediate production of ATP in the muscle? (a), (b), (c), (d), (e) Phosphocreatine a. Provides sustained energy during heavy activity b. Fuels glycolysis during quick bursts of heavy activity c. Maintains homeostasis by always providing low levels of ATP during rest d. Provides small amounts of ATP during heavy activity e. Is a phosphorylated amino acid important in muscle proteins

Explanation / Answer

17. a

Explanation: Substrate level phosphorylation involves formation of ATP when phosphate group is transferred from a phosphorylated compound to ADP
