Question
Chapter 28, Problem 28.6P
Interpretation Introduction
Interpretation:
Number and name of each kinases involved in glycolysis should be determined.
Concept introduction:
Glycolysis is the biochemical pathway that breaks down glucose to pyruvate and produces chemical energy. The body utilizes this energy in various day to day activities. Various enzymes are involved in the glyolysis process.

Kinases are enzymes that catalyze the addition (or removal) of a phosphate group to ( or from) a substance. ATP is also involved. How many kinases are in glycolysis? Name them.
Why are some metabolic reactions coupled to the hydrolysis of ATP?
To drive the nonspontaneous reaction
To extend the half-life of enzymes
To increase the equilibrium constant
To bypass metabolic regulation
Determine the direction that each of the reactions will progress.
Assume that the reactants and products are present in equimolar amounts. The standard free energy of hydrolysis of ATP is –30.5 kJ/mol.
fructose+ATP ____fructose 6‑phosphate+ADP
The standard free energy of hydrolysis for fructose 6‑phosphate is −15.9 kJ/mol.
3‑phosphoglycerate+ATP___1,3‑bisphosphoglycerate+ADP
The standard free energy of hydrolysis for 1,3‑bisphosphoglycerate is −49.3 kJ/mol.
