The concentration of PEP at 25°C, assuming that the pyruvate kinase reaction is at equilibrium in the cell. Introduction : Glycolysis is the first stage of cellular respiration in which glucose is broken down into two pyruvic acid molecules by the action of enzymes which results in formation of net two ATP molecules. Phosphoenolpyruvate is one of the phosphoryl group donors in the synthesis of molecules of ATP during glycolysis.

Answer 1

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.
