The reason why Kreb’s cycle operates only under aerobic conditions even though it does not use molecular oxygen in any of its reactions. Introduction: Cellular respiration involves a set of metabolic reactions and processes during which biochemical energy from various nutrients is converted into energy. Glycolysis, citric acid cycle, and oxidative phosphorylation are the essential steps of cellular respiration. Kreb’s cycle, also known as citric acid cycle or tricarboxylic acid cycle (TCA), is a metabolic pathway that connects carbohydrate, fat, and protein metabolism .

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
