Question

Anaerobic respiration of yeast produces
A. N₂
B. O₂
C. CO₂
D. H₂O

Answer 1

Hint:
It's essential to understand the terminology used to describe Anaerobic respiration before you can proceed to the question.
When there is no oxygen present, cells can use anaerobic respiration to break down sugars and produce energy. Contrast this with aerobic respiration, which uses oxygen to make energy and is extremely efficient. Due to its strong affinity for electrons, molecular oxygen is the most effective electron acceptor for respiration. Some creatures can, however, breathe without oxygen because they have evolved to employ different final electron acceptors.

Complete step by step answer:
Anaerobic respiration is an oxygen-independent respiration process, which enables an organism to create energy even in the absence of oxygen in the surrounding environment. Here we are going to explore all possible topics about anaerobic respiration in yeast.
Yeast begins to respire anaerobically when there is no oxygen present in the surroundings. This mechanism causes glucose or sugar molecules to go through glycolysis and break down into pyruvate. As the pyruvate decomposes further, ethanol and carbon dioxide are produced along with a tiny quantity of energy. Anaerobic respiration is the term used to describe this process in yeast.
As mentioned above, In the absence of oxygen the yeast will transition to anaerobic respiration, where it ferments sugars to make ethanol, carbon dioxide, and energy.

Option ‘C’ is correct

Note:
These are the reactions that need an electron acceptor to drive them, such as oxygen, sulphate, nitrate, etc. Only anaerobic respiration is possible for many bacteria and archaea. Numerous additional creatures have the ability to breathe either aerobically or anaerobically, depending on the presence of oxygen. Anaerobic respiration allows humans and other creatures to survive in the absence of oxygen while extending the life or function of their cells.
