Correct option is D
The correct answer is (d) Respiration in presence of oxygen.
Key Points:
· Aerobic respiration is the process by which cells generate energy in the presence of oxygen.
· During aerobic respiration, glucose is completely broken down into carbon dioxide and water, releasing a significant amount of energy in the form of ATP (adenosine triphosphate).
· This process occurs in the mitochondria of the cell and is the most efficient way of producing energy.
Information Booster:
·
Respiration through skin: Known as cutaneous respiration, seen in some amphibians and certain other organisms.
·
Respiration without molecular oxygen: This is anaerobic respiration, where energy is generated without the use of oxygen, often producing lactic acid or ethanol as by-products.
·
Respiration through gills: Known as branchial respiration, this is typical in aquatic animals like fish.
