AP BIOLOGY

Detailed explanation-1: -Glycolysis. Glycolysis is the first pathway in cellular respiration. This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecules.

Detailed explanation-2: -Like aerobic respiration, anaerobic respiration involves glycolysis, a transition reaction, the citric acid cycle, and an electron transport chain.

Detailed explanation-3: -Therefore, these two pathways are called lactic acid fermentation and alcoholic fermentation.

Detailed explanation-4: -Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that’s performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end.
