What are the four stages of areobic respiration in plants and animals?
yes that’s the equation. there are four stages of aerobic respiration; glycolysis (in the cytoplasm) – where a glucose molecule (6C) is broken down into two pyruvate molecules (3C) in a series of intermediate reactions where 2 ATP molecules are used and 4 ATP molecules are synthesised. 2 reduced NAD are also formed from dehydrogenation. link reaction (in the mitochrondrial matrix) – the pyruvate molecules are dehydrogenated (to give reduced NAD) and decarboxylated to give acetyl which is then combined with coenzyme A to give acetyl coenzyme A. kreb’s cycle (in the mitochondrial matrix) – acetyl is released and combined with oxaloacetate to give citrate (6C) it is then dehydrogenated (four times) and decarboxylated (twice) where 3 reduced NAD and 1 reduced FAD molcules are obtained aswell as an ATP molecule oxidative phosphorylation (on the stalked particles of christae) – the reduced NAD and FAD release the H atoms which are then are passed down hydrogen carriers to break them into a p
