Question

In which compartment of the cell does anaerobic respiration occur?

Answer 1

Hint: The process of anaerobic respiration takes place in that compartment of a cell which is semi-viscous fluid i.e matrix which is present in the cell and is surrounded by the cell membrane. This fluid contains many different types of enzymes, proteins, nutrients, and other cell organelles.

Complete solution:
Anaerobic respiration is a process of respiration that takes place in absence of oxygen. It occurs inside the cytoplasm of the cell. Aerobic respiration takes place within the mitochondria of the cell in presence of oxygen. The final product of anaerobic respiration is carboxylic acid in animals and alcohol in plants.
Most organisms need oxygen for respiration but some organisms and tissues can still respire if the oxygen runs out. In conditions when there is low or no oxygen, the process of anaerobic respiration takes place. The 'an' in 'anaerobic' means without.
During anaerobic respiration, not all of the energy will be released in the oxidation of glucose from the glucose molecule because it is just partially broken down. This means that the oxidation of glucose is incomplete. The cytoplasm basically has three elements in it. The cytosol, organelles, and inclusions are the major elements of the cytoplasm.
-The cytosol is that portion of the cytoplasm which is not contained within membrane-bound organelles. Cytosol makes up about the majority of the cell volume and is a complex mixture of cytoskeleton filaments, dissolved molecules, and water.

So, the correct answer is ‘Cytoplasm’.

Note:
-Organelles are the membrane-bound structures present inside the cell in the cytoplasm that has specific functions. For example mitochondria, ribosomes, etc.
-Cytoplasmic inclusions- These inclusions are small particles of insoluble substances suspended in the cytosol.
