Citric acid (or citrate) is an allosteric inhibitor of one of the first enzymes in glycolysis. How, in general, will it affect cellular respiration? Glycolysis will slow down when citric acid is abundant It will compete with glucose for the active site of the enzyme. It will stop the citric acid cycle when pyruvate is abundant. All of the above

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.
