Question

Some cells can carry out what process to make ATP when there's NO oxygen?

Answers

Cells can carry out **anaerobic respiration** or **fermentation** to make ATP in the absence of oxygen. In this process, glucose is partially broken down to generate ATP without using oxygen. Different types of fermentation include:

1. **Lactic acid fermentation**: Common in muscle cells and some bacteria, this process converts glucose into lactic acid and produces a small amount of ATP.

2. **Alcoholic fermentation**: This occurs in yeast and some bacteria, where glucose is converted into ethanol and carbon dioxide, also yielding a small amount of ATP.

Both processes allow for energy production in environments where oxygen is limited or unavailable.
