Final answer:
Oxidative energy generation occurs in the mitochondria of a cell, which are dubbed "powerhouses" because they produce most of the cell's ATP. This is achieved through cellular respiration, a process involving the breakdown of nutrients like glucose and fatty acids.
Step-by-step explanation:
Oxidative energy takes place in the mitochondria of our cell and uses a combination of muscle glycogen, intramuscular fatty acids, and fatty acids. The mitochondria are often referred to as the "powerhouses" or "energy factories" of a cell because they are responsible for making adenosine triphosphate (ATP), the cell's main energy-carrying molecule. This process of ATP production inside the mitochondria is known as cellular respiration.
Why is the mitochondria considered the powerhouse of the cell? The correct answer is b. Most of the ATP is produced in mitochondria by oxidative phosphorylation. Fatty acids and glucose from the circulation are broken down within the mitochondria to release energy in the form of ATP. Glycogen and fatty acid droplets stored within the sarcoplasm act as additional nutrient supplies for this energy production process.
