ATP ADENOSINE TRIPHOSPHATE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is the most important biological molecule that provides energy.
A
Adenosine diphosphate (ADP)
B
Adenosine triphosphate (ATP)
C
NADPH
D
NADP
Explanation: 

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 triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Detailed explanation-3: -Adenosine triphosphate (ATP) is probably the most important phosphate compound of all. It is the universal energy “currency” for all known life forms. ATP and its reaction products provide or store energy for all organism activity.

Detailed explanation-4: -Adenosine triphosphate, also known as ATP, is the cellular energy currency. They are molecules that carry energy and are created as a byproduct of photophosphorylation reactions. Minerals, carbohydrates, lipids, proteins, etc. are the main energy sources for ATP.

Detailed explanation-5: -Lipmann focused on phosphate bonds as the key to ATP being the universal energy source for all living cells, because adenosine triphosphate releases energy when one of its three phosphate bonds breaks off to form ADP.
