Question

Type of respiration process in yeast ______.

Options

• is strictly aerobic

• is strictly anaerobic

• depends on presence or absence of oxygen

• depends on nature of substrate

Answer 1

Type of respiration process in yeast depends on presence or absence of oxygen.

Explanation:

In the presence of oxygen, yeast can undergo aerobic respiration, producing carbon dioxide and water as byproducts. However, in the absence of oxygen, yeast can switch to anaerobic respiration, known as fermentation, producing carbon dioxide and ethanol as byproducts.
