Answer 1

Answer: The end-products of the complete aerobic oxidation of glucose are:

II. ATP

III. CO₂

V. H₂O

Step-by-step explanation:

Glucose undergoes a series of reactions through glycolysis, the Krebs cycle, and the electron transport chain to produce ATP, carbon dioxide (CO₂), and water (H₂O) as the main end-products.

During glycolysis, glucose is converted into pyruvic acid (VI), which then enters the mitochondria. In the Krebs cycle, pyruvic acid is further oxidized, resulting in the release of carbon dioxide. The carbon dioxide produced in the Krebs cycle is a waste product and is eventually expelled from the body.

The electron transport chain, which occurs in the inner mitochondrial membrane, generates ATP through a process called oxidative phosphorylation. Oxygen acts as the final electron acceptor, forming water as a byproduct.

Therefore, the correct answer is:

D. II, III, V. (ATP, CO₂, H₂O)
