Question

How many atp equivalents are expended to convert 2 pyruvates to 1 glucose? a. 2 b. 4 c. 6 d. 8

Answer 1

4 ATP and 2 GTP equivalents are expended to convert 2 pyruvates to 1 glucose in gluconeogenesis.

• The process through which glucose is produced from non-carbohydrate metabolites is known as gluconeogenesis.
• Pyruvate, lactate, a few gluconeogenic amino acids, and glycerol, which is mostly produced by fat metabolism, are the main gluconeogenic precursors.
• Four ATP, two GTP, and two NADH are required to produce each molecule of glucose from two pyruvate molecules. At a cost of 6 ATP molecules used in gluconeogenesis, glycolysis generates 2 ATP molecules.
• Pyruvate is converted back to glucose during gluconeogenesis by the following steps:

2 Pyruvate+ 4 ATP + 2 GTP + 2 NADH + 2 H > Glucose + 4 ADP + 2 GDP + 6 Pi + 2 NAD + (2)

• Even though it includes many of the same processes as glycolysis,
• Must make use of a variety of "new" reactions to avoid huge
• Favorable improvements in standard free energy
