Since fermentation occus in the cytoplasm of yeast cells explain the role of mitochondria in yeast cells?

Mitochondria are involved in aerobic cellular respiration.

Fermentation is part of the process of cellular respiration. In the presence of oxygen, further processing of the fermentation products will occur in the mitochondria, yielding more ATP.

Without oxygen - fermentation occurs, and there's no further processing in the mitochondria

hope this helps :)

Thank u guys ;)

The mitochondria in yeast cells play a crucial role in energy production and respiration, despite fermentation occurring in the cytoplasm. While fermentation produces small amounts of energy, it is less efficient compared to cellular respiration, in which the mitochondria are actively involved.

To explain the role of mitochondria in yeast cells, consider the following points:

1. Energy Production: Mitochondria are known as the powerhouse of the cell because they generate the majority of the cell's energy in the form of adenosine triphosphate (ATP) through cellular respiration. During respiration, carbohydrates and other molecules are broken down to produce ATP, which is the energy currency of the cell. Even though yeast cells predominantly undergo fermentation, they still require some ATP produced by the mitochondria for essential cellular processes.

2. Oxygen Utilization: Fermentation in yeast cells occurs in anaerobic (oxygen-depleted) conditions. However, under aerobic (oxygen-rich) conditions, yeast cells can switch from fermentation to cellular respiration. During this switch, mitochondria play a vital role in utilizing oxygen to perform oxidative phosphorylation, the final step of cellular respiration. Through oxidative phosphorylation, mitochondria can produce a significant amount of ATP, making energy production more efficient.

3. Metabolic Regulation: Mitochondria also play a critical role in metabolic regulation within yeast cells. They are involved in numerous metabolic pathways, detoxification of harmful molecules, and synthesis of cellular components. Through their metabolic functions, mitochondria help maintain the overall homeostasis and functionality of yeast cells.

In summary, although fermentation occurs in the cytoplasm of yeast cells, the mitochondria are still essential due to their role in energy production, oxygen utilization, and metabolic regulation.

Without oxygen -- well, fermentation occurs, and there's no further processing in the mitochondria.
