By the end you’ll be able to

explain the structure of ATP and how ATP transfers energy in cells by hydrolysis and phosphorylation, including its role as the immediate source of energy for biological processes
describe glycolysis in the cytoplasm as the phosphorylation of glucose, lysis to triose phosphate, oxidation to pyruvate, and net production of ATP and reduced NAD

explain the link reaction and the Krebs cycle in the mitochondrial matrix, including decarboxylation, dehydrogenation, production of carbon dioxide, reduced NAD, reduced FAD and ATP

explain oxidative phosphorylation in mitochondria, including electron transport chains, the role of oxygen as the final electron acceptor, proton pumping, chemiosmosis and ATP synthesis by ATP synthase

compare aerobic and anaerobic respiration in animals, plants and microorganisms, including lactate formation and ethanol plus carbon dioxide formation

interpret and evaluate experimental evidence and data on respiration, including respiratory substrates, respiratory quotient, respirometers and the effects of exercise, temperature or metabolic demand on respiratory rate
