Because during the TCA Cycle (aka Kreb’s Cycle), energy is both consumed and produced. During the TCA cycle, acetyl coA is converted to CO2 and H2O but. The citric acid cycle is the central metabolic hub of the cell. It is the final common pathway for the oxidation of fuel molecule such as amino acids. Amphibolic Nature Of TCA Cycle: In aerobic organisms, the citric acid cycle is an amphibolic pathway, one that serves in both catabolic and anabolic processes.

Questions on Lipid Metabolism and Glyoxylate ycle 1. When we completed the Krebs cycle, all of the bonds between. Describe how is made in the second stage of cellular respiration. Breaking down a protein into amino acids or a triglyceride into fatty acids or a disaccharide into monosaccharides are all hydrolysis or catabolic reactions.

A similar process takes place in many prokaryotic. Answer c is incorrect. Some bacteria are strict aerobes and others are strict anaerobes.

Oxidation of food materials releases cellular energy ATP is called cellular respiration 2.
