Question

Which label identifies the part of the ATP molecule that changes when energy is released in the cells of all living things, and what is the name of this process?
A; respiration
B; metabolism
C; respiration
D; photosynthesis

Answer 1

Answer:

C; respiration

Explanation:

• Cellular respiration is the process by which nutrients such as glucose are broken down using oxygen to generate energy in the form of ATP, that is used to drive cellular processes.
• ATP consists of an adenosine molecule bonded to three phosphate groups in a row. Energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP.
• When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

Answer 2

Answer:

C: Respiration

Explanation:

Respiration is the process of oxidation of nutrients to release the energy stored in them. The released energy is used to add terminal phosphate to the ADP (Adenosine diphosphate) and leads to formation of ATP (Adenosine triphospate). ATP serves as energy currency for cells and drives the other endergonic processes.
