Question

TCA cycle involves inter conversion of carbohydrate molecules. Which process takes place only once during completion of one Krebs cycle​

Answer 1

The tricarboxylic acid cycle is the major energy-yielding metabolic pathway in cells, providing the greater part of the reduced coenzymes that will be oxidized by the electron transport chain to yield adenosine triphosphate (ATP). The pathway is sometimes known as the citric acid cycle, or the Krebs' cycle, after its discoverer, Sir Hans Krebs. In addition to its role in energy-yielding metabolism, and the oxidation of 2-carbon units, the cycle is also the major pathway for interconversion of 4- and 5-carbon compounds in the cell, many of which arise from, or are intermediates in the synthesis of, amino acids. Oxaloacetate, a key intermediate in the cycle, is the main precursor for gluconeogenesis in the fasting state.

Answer 2

Answer:

Correct option is A. Isomerization
