AP BIOLOGY

Detailed explanation-1: -In a eukaryotic cell, biochemical activities are compartmentalized in small subcellular compartments call organelles. ATP, the energy currency of the cell, is made in an organelle called the “mitochondrium” (pl. “mitochondria").

Detailed explanation-2: -Mitochondria, for example, are organelles that provide eukaryotes with most of their energy by producing energy-rich molecules called ATP.

Detailed explanation-3: -Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells. As reviewed in Chapter 2, they are responsible for most of the useful energy derived from the breakdown of carbohydrates and fatty acids, which is converted to ATP by the process of oxidative phosphorylation.

Detailed explanation-4: -Abstract. Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation.

Detailed explanation-5: -Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration.
