Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What do all cells use as its energy source?
A
Carbohydrates
B
Protein
C
Lipids
D
ATP
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: -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-3: -ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds in ATP, it is readily hydrolyzed in reactions to release a large amount of energy.

Detailed explanation-4: -ATP is the energy currency of the cell because it is the most preferred energy molecule in the cell. Its preference is due to the following factors: It donates its phosphoryl groups to release energy.
