ATP is broken down to ADP and Pi when energy is required to carry out the metabolic process. ATP is also released during the metabolic process.
<u>Explanation:</u>
The pumping of hydrogen ions across the inner membrane creates concentration gradient where there is higher concentration of the ions in the intermembrane space than in the matrix. This chemiosmotic gradient causes the ions to flow back across the membrane into the matrix, where their concentration is lower.
ATP synthase behaves as a channel protein thereby helping the hydrogen ions cross the membrane. It also has the ability to act as an enzyme, forming ATP from ADP and inorganic phosphate.
After passing through the electron transport chain, the used electrons joins with oxygen to form water. That is why oxygen is required. In the absence of oxygen, this process will not occur.
The breakdown of carbohydrates into glucose. Glucose use to obtain energy (ATP) for the human cellular respiration by the steps glycolysis, acetyl CoA and kreb cycle. In glycolysis, ATP is use to generate greater ATP called the ATP debt. Fat (lipid) and protein (amino acid) also can give human energy call gluconeogenesis but only when critical condition only.
The earth rotates 24 hours.
The sun rotates once every 25 days
