Cellular respiration is the process by which cells in the body convert glucose and oxygen into energy in the form of adenosine triphosphate (ATP). Although I was unable to fetch specific information, I can provide a general overview of cellular respiration in humans.

The process of cellular respiration in humans typically consists of three main stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation.

1. Glycolysis: This is the initial step in cellular respiration and occurs in the cytoplasm of cells. During glycolysis, a molecule of glucose is broken down into two molecules of pyruvate, generating a small amount of ATP and NADH.

2. Citric Acid Cycle (Krebs Cycle): If sufficient oxygen is available, the pyruvate molecules produced during glycolysis enter the mitochondria to undergo the citric acid cycle. In this cycle, the pyruvate is further broken down, releasing carbon dioxide and generating high-energy electron carriers like NADH and FADH2.

3. Oxidative Phosphorylation: The final stage of cellular respiration takes place in the inner mitochondrial membrane. NADH and FADH2 from the previous steps donate their electrons to the electron transport chain. As electrons are passed along the chain, their energy is used to pump protons (H+) across the inner mitochondrial membrane, creating an electrochemical gradient. Ultimately, this gradient drives ATP synthesis through the enzyme ATP synthase, resulting in the production of a large amount of ATP.

Overall, cellular respiration in humans is a highly efficient process that allows cells to extract energy from glucose and convert it into ATP, which is used to power various cellular activities. The specific details and regulation of cellular respiration can vary depending on the cell type and physiological conditions.
