ATP is a source of free energy that drives unfavorable reactions. Which of the processes are coupled to the dephosphorylation of ATP? a. de novo (from scratch) anabolism of nucleotides b. the exergonic hydrolysis of creatine phosphate c. reversible isomerization of glucose‑6‑phosphate to fructose‑6‑phosphate during glucose catabolism d. myosin action during muscle contraction e. membrane transport that maintains levels in cells One reason that ATP is a source of energy is that the products of ATP hydrolysis have less free energy than the reactants. Why? formation of ion pairs involving ATP resonance stabilization of free phosphate electrostatic repulsion in ATP hydrogen bonding between free phosphate and water.

Answer:

The correct statements are a denovo anabolism of nucleotides d myosin action during muscle contraction e membrane transport that maintain levels in the cell.

Explanation:

ATP or adenosine tri phosphate is an high energy compound.The hydrolysis of ATP helps to drive many thermo dynamically unfavorable reaction.The processes which are coupled to the de phosphorylation of ATP are given below.

1 De novo synthesis of nucleotides that requires energy in form of ATP.

2 During muscle contraction the sliding of thick filaments or myosin over thin filament or actin requires energy derived from the hydrolysis of ATP.

3 Membrane transport basically active transport helps in the uphill transport of ions that requires free energy in form of ATP.
