what accounts for the difference of ATP production in anaerobic and aerobic respiration?

Answer 1

In anaerobic respiration the glucose molecule is not broken down very much - just into a couple of relatively large molecule of pyruvate - so there is still a lot of energy stored in those molecules.

In aerobic respiration the glucose molecule is broken down into much smaller molecules, and the electrons that are kept from the break-down are sent through the electron transport chain so many more ATP molecules can be made.

Answer 2

in anaerobic respiration you only get ATP from glycolysis,

in aerobic respiration a link reaction alllows the krebs cycle to work, which gives products from greater breakdown of glucose that go on to make ATP - in fact most ATP comes from the electron transport chain which brings together al the reduced coenzymes from glycolysis, link reaction and krebs cycle, and only works with oxygen present.

Answer 3

anaerobic respiration produces 2 ATP, while aerobic respiration produces 36 (because of the process of oxidative phosphorylation)
