Energy is released from ATP when
a
a phosphate group is added
b
a phosphate group is removed from ATP
c
adenine bonds to ribose
d
ATP is exposed to light
b
a phosphate group is removed from ATP
The correct answer is b) a phosphate group is removed from ATP. When ATP (adenosine triphosphate) is converted to ADP (adenosine diphosphate) and inorganic phosphate (Pi), energy is released. This conversion occurs when a phosphate group is cleaved from ATP, resulting in the release of energy that can be used for cellular processes.
The correct answer is option (b): a phosphate group is removed from ATP.
ATP (adenosine triphosphate) is a molecule that stores and releases energy within cells. It consists of adenine (a nitrogenous base), ribose (a sugar), and three phosphate groups. The release of energy from ATP occurs when a phosphate group is removed from the molecule, converting it into ADP (adenosine diphosphate).
To get the answer to this question, it is important to have a basic understanding of ATP's structure and function. ATP is commonly referred to as the "energy currency" of the cell because it provides energy for various cellular processes.
When a phosphate group is removed from ATP, it undergoes hydrolysis, which is the process of breaking a bond using water. This hydrolysis reaction results in the formation of ADP and a free inorganic phosphate (Pi), along with the release of energy. The energy released during this reaction can be utilized to drive other cellular processes and perform work.
Therefore, option (b) is the correct choice as it accurately describes the release of energy from ATP when a phosphate group is removed.
