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.

Therefore every amino acid degradation pathway has a key step where the amino group is. Human Biology Higher Homework: Some bacteria are strict aerobes and others are strict anaerobes. This page nnature last modified at 30 October Intermediates of TCA cycle are utilised for synthesis of various compounds.

These are the most common ways smaller organic molecules can be formed into more complex ones and applies to the formation of carbs, proteins, lipids and nucleic acids. Respiration and Photosynthesis Test Mr. Phosphofructokinase and pyruvate dehydrogenase”. These chemical reactions are generally of two types: Page 18 Respiration Syllabus: A four- carbon compound oxaloacetate condenses with a two-carbon acetyl unit to yield a six-carbon tricarboxylic acid citrate.
