Question

Which of the following is a function of the mitochondrion?

1) Tricarboxylic acid cycle enzyme reactions
2) Electron transport
3) ATP synthesis
4) All of the choices are correct.

Answer 1

4) All of the choices are correct. The mitochondrion is responsible for multiple functions, including the tricarboxylic acid cycle enzyme reactions, electron transport, and ATP synthesis.

Step-by-step explanation:

The mitochondrion is responsible for several important functions in the cell, making it the powerhouse of the cell. These functions include:

Tricarboxylic acid cycle enzyme reactions: The mitochondrion is the site of the tricarboxylic acid cycle, also known as the Krebs cycle or citric acid cycle. In this cycle, high-energy molecules such as ATP, NADH, and FADH2 are created through a series of enzyme reactions.Electron transport: The mitochondrion houses the electron transport chain, which is responsible for passing electrons from high-energy molecules like NADH and FADH2 to generate more ATP molecules.ATP synthesis: Through oxidative phosphorylation in the mitochondrion, most of the ATP in the cell is produced, providing the energy needed for various cellular processes.All of the choices are correct: In summary, all of the given choices are correct; the mitochondrion participates in the tricarboxylic acid cycle enzyme reactions, electron transport, and ATP synthesis.
