Final answer:
Cellular respiration is the process that requires energy from respiration to produce ATP, which is necessary for various cellular functions such as molecule synthesis and transport.
Step-by-step explanation:
The process in the cell that requires energy from respiration is termed cellular respiration. This intracellular process breaks down glucose with oxygen to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate).
ATP is essential for powering various cellular activities, including synthesis and breakdown of molecules, transport of molecules across the cell membrane, and muscle contraction. Cellular respiration is a multi-step process including glycolysis, the transformation of pyruvate into acetyl-CoA, the Krebs cycle, and oxidative phosphorylation.
