Answer:
1.A. Glycolysis;
2.A. fermentation pathways;
3.C. electron transport chain;
4.A. less.
Explanation:
Anaerobic respiration involves breakdown of glucose molecule to produce energy in the absence of oxygen, while during aerobic respiration, glucose completely breaks down to produce energy, and carbon dioxide and water as byproducts.
'Both aerobic and anaerobic respiration involve 'the process of glycolysis' to produce ATP and NADH molecules' as glycolysis is a universal process that takes place in all living organisms.
In anaerobic respiration, NAD+ molecules, used in glycolysis are regenerated from NADH by 'fermentation pathways' while in aerobic respiration NAD+ are regenerated from NADH during 'electron transport chain.'
During anaerobic respiration, partial oxidation of glucose takes place that produce a 'less amount of ATP molecules' than aerobic respiration. It produces only 2 ATP molecules per molecule of glucose while aerobic respiration produces 32 ATP molecules per molecule of glucose.
