Appropriate voluntary and involuntary motor responses are made by initiating muscular contractions or glandular secretions. Human Biology. This occurs in both glycolysis and the citric acid cycle. This breakdown of glucose into pyruvate therefore results in a net gain of ATP molecules in this energy payoff stage. Physiology and Health - Higher Biology Revision - BBC Bitesize All cells produce substances that are essential for them to function properly. The production of pyruvate from glucose involves the production of several intermediate molecules. If oxygen is available (aerobic conditions), pyruvate molecules progress into the citric acid cycle. Higher Biology learning resources for adults, children, parents and teachers organised by topic. Cellular respiration refers to the breakdown of glucose and other respiratory substrates to make energy carrying molecules called ATP. All metabolic pathways together form a complex network that is necessary to maintain life.
