Question

sometimes some animals perform anaerobic respiration give examples​

Answer 1

Human beings erythrocytes and muscle cells are examples

Answer 2

• Sometimes there is depletion in oxygen level in the surroundings.
• Due to this, the body gets deprived of oxygen.
• But, oxygen is necessary for proper functioning of the body.
• Hence, sometimes animals perform anaerobic respiration due to lack of oxygen to fulfill their metabolism to some extent.
• The energy produced in this case is very less, about 2 ATP, but it proves to be helpful for the animal.

Example :- Muscle cells of animals and humans perform anaerobic respiration during heavy exercise to maintain oxygen level in the body, due to which we feel tired.
