ATP ADENOSINE TRIPHOSPHATE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When ATP loses a phosphate, and becomes ADP, is energy being released or stored?
A
released
B
stored
Explanation: 

Detailed explanation-1: -If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

Detailed explanation-2: -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-3: -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-4: -Answer and Explanation: When one of the phosphates is removed, the energy stored in the covalent bond is released, and the cell is able to do work. The molecule that is left over is called adenosine diphosphate, or ADP. There are two phosphates left attached to the adenine group.

Detailed explanation-5: -Posted August 3, 2021. ATP (adenosine triphosphate) stores energy in its high energy phosphate bonds. ATP consists of an adenosine molecule bonded to three phosphate groups in a row. During cellular respiration, energy in food is converted into chemical energy that can be used by cells.
