4.2 Respiration releases chemical energy from organic molecules
You should be prepared to discuss...
(a) All living organisms carry out respiration in order to provide energy in the cell.
(b) Glycolysis as a source of triose phosphate, pyruvate, ATP and reduced NAD. The formation of acetyl CoA.
(The names of intermediates are not required.)
(c) The Krebs cycle as a means of liberating energy from carbon bonds to provide ATP and reduced NAD with release of carbon dioxide. The role of reduced NAD as a source of electrons and protons for the electron transport system. The energy budget of the breakdown of glucose under aerobic and anaerobic conditions. Fat and amino acid utilisation.

Glycolysis
Glycolysis - Khan AcademyThis is a really good explanation of the process.
Glycolysis - iMedical SchoolN.B.: This is high level. You do not need to know all the enzymes, intermediaries or biochemical structures on this video BUT this is all useful background and should be essential viewing for all those interested in medicine and pharmacology.
