During cellular respiration cells obtain energy for performing work when?

Answer 1

During cellular respiration, cells obtain energy by breaking down glucose and other organic molecules in the presence of oxygen. This process generates adenosine triphosphate (ATP), the primary energy currency of the cell, through a series of metabolic pathways including glycolysis, the citric acid cycle, and oxidative phosphorylation. The ATP produced is then utilized by the cell to perform various functions, such as muscle contraction, active transport, and biosynthesis.
