GENERAL KNOWLEDGE

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: -When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

Detailed explanation-4: -ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.

Detailed explanation-5: -ATP is made in the mitochondria, which are the organelles in the cell where cellular respiration takes place. This is why mitochondria are often referred to as “the powerhouse of the cell”.
