Question

what does glycolysis produce? oxygen pyruvate lactic acid alcohol in which stage of cellular respiration is the most atp produced? glycolysis krebs cycle electron transport chain fermentation

Explanation:

Glycolysis is the metabolic pathway that breaks down glucose. It produces pyruvate as its end - product. Oxygen is not a product of glycolysis. Lactic acid is produced in lactic acid fermentation (a type of anaerobic respiration that can occur after glycolysis in some cells). Alcohol is produced in alcoholic fermentation (another type of anaerobic respiration after glycolysis in yeast).

For the second question, the electron transport chain is the stage of cellular respiration where the most ATP is produced. Glycolysis produces a small amount of ATP (net 2 ATP per glucose molecule). The Krebs Cycle also produces a relatively small amount of ATP (1 ATP per turn, and 2 turns per glucose). Fermentation does not produce additional ATP beyond what is produced in glycolysis.

Answer:

Pyruvate; Electron Transport Chain
