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: -Adenosine 5′-triphosphate, abbreviated ATP and usually expressed without the 5′-, is an important “energy molecule” found in all life forms. Specifically, it is a coenzyme that works with enzymes such as ATP triphosphatase to transfer energy to cells by releasing its phosphate groups.

Detailed explanation-3: -One of the first and most enduring facts most students learn in biology class is that all living cells use a small molecule called adenosine triphosphate (ATP) as fuel.

Detailed explanation-4: -It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP.

Detailed explanation-5: -Each cell in the human body contains about a billion ATP molecules, and the power derived from the breakdown of them is used to deliver substances to their cellular homes, build needed complex molecules and even make muscles contract. “ATP is the fuel of life.
