Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is used by cells for energy?
A
DNA
B
ATP
C
RNA
D
ADP
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: -Glucose is the main source of fuel that our cells’ mitochondria use to convert caloric energy from food into ATP, which is an energy form that can be used by cells. ATP is made via a process called cellular respiration that occurs in the mitochondria of a cell.

Detailed explanation-3: -ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.

Detailed explanation-4: -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.
