What does mitochondrion do in the animal cell?

Answer 1

Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.

Answer 2

By the process of the citric acid cycle and the oxidative phosphorilation of carbohydrates the electrons stripped are put through the electron transfer chain and ATP is synthesized as the energy source to do cellular work.

Answer 3

Mitochondria are the powerhouse of the cell, producing energy in the form of ATP through cellular respiration. They play a crucial role in metabolism and are involved in other cellular processes such as signaling and apoptosis.

Answer 4

Mitochondria are the site of cellular respiration - which produces ATP, a form of energy that the cell can use.
