The end product of glycolysis and how the carbons of this molecule are used in stage I of cellular respiration . Also, determine the most frequent form of energy captured in Kreb’s cycle. Introduction: The breakdown of glucose is carried out in two major processes: glycolysis and cellular respiration. Glucose breakdown starts in the cytosol of the cell through glycolysis and further proceeds to the cellular respiration in the presence of oxygen. Glycolysis involves the breakdown of glucose into two molecules of pyruvate in the presence of oxygen or lactate in the absence of oxygen. Two ATP molecules are generated per glucose molecule during glycolysis.

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.
