AP BIOLOGY

Detailed explanation-1: -Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

Detailed explanation-2: -Explanation: ATP, also known as Adenosine Triphosphate is a usable form of energy. ATP is also formed by various processes in plants and animals. ATP collects energy from the food-burning power plants of the cell and transports it to the parts of the body where it is needed.

Detailed explanation-3: -In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes-glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation-to produce ATP.

Detailed explanation-4: -ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.

Detailed explanation-5: -Nutritional supplements designed to increase adenosine 5′-triphosphate (ATP) concentrations are commonly used by athletes as ergogenic aids. ATP is the primary source of energy for the cells, and supplementation may enhance the ability to maintain high ATP turnover during high-intensity exercise.
