The end products of aerobic respiration include carbon dioxide, water, and energy. Let's break down the process and understand how these products are formed.

1. Glycolysis:
Glycolysis is the first step of aerobic respiration, which occurs in the cytoplasm. During this process, a glucose molecule is broken down into two molecules of pyruvate. In this step, a small amount of ATP is produced, along with some NADH.

2. Pyruvate decarboxylation:
The pyruvate molecules produced in glycolysis enter the mitochondria. Here, each pyruvate is converted into acetyl-CoA in a process called pyruvate decarboxylation. This step releases carbon dioxide as a waste product and produces NADH.

3. Citric Acid Cycle (Krebs cycle):
The acetyl-CoA molecules produced in pyruvate decarboxylation enter the citric acid cycle. In this cycle, the acetyl group from acetyl-CoA is oxidized, releasing carbon dioxide as a byproduct. The NADH and FADH2 molecules are also produced during this cycle, which carry high-energy electrons to the next step.

4. Electron Transport Chain (ETC):
The high-energy electrons carried by NADH and FADH2 are transferred to the electron transport chain, located on the inner mitochondrial membrane. The electrons move through a series of protein complexes, and their energy is used to pump protons (H+) across the membrane, creating an electrochemical gradient. This gradient is used to generate ATP through a process called oxidative phosphorylation.

5. Oxygen as the final electron acceptor:
In the electron transport chain, the final electron acceptor is molecular oxygen (O2). Oxygen combines with electrons and protons to form water (H2O). This step is crucial since it allows the continuous flow of electrons through the electron transport chain.

Overall, the complete oxidation of glucose during aerobic respiration produces a total of 36-38 ATP molecules. Along with ATP, the end products of aerobic respiration are carbon dioxide (CO2) and water (H2O). These waste products are eliminated from the body through exhalation (CO2) and urine or sweat (H2O).

Therefore, the correct answer is option C) carbon dioxide, water, and energy.

Aerobic respiration is an enzymatically controlled release of energy in a stepwise catabolic process of complete oxidation of organic substrate into CO2 and H2O with O2 acting as terminal oxidant.
