The question is incomplete as it does not have the options which are:
a. Most of the free energy available from the oxidation of glucose is used in the production of ATP in glycolysis.
b. Glycolysis is a very inefficient reaction, with much of the energy of glucose released as heat
.c. Most of the free energy available from the oxidation of glucose remains in pyruvate, one of the products of glycolysis.
d. There is no CO2 or water produced as products of glycolysis.e. Glycolysis consists of many enzymatic reactions, each of which extracts some energy from the glucose molecule.
Answer:
Most of the free energy available from the oxidation of glucose remains in pyruvate, one of the products of glycolysis.
Explanation:
Glycolysis refers to the breakdown of the glucose molecules during the complex process of cellular respiration. The process takes place in ten enzymes catalyzed reactions that form the 2 molecules of pyruvate.
The glycolysis process releases a lot of energy which is measured as -686 kcal/mol.
The energy is not released into the reaction directly but is conserved in pyruvate form and less is released into driving the reduction of NAD to NADH.
Thus, the selected option is correct.
