This is called anaerobic respiration. This is because to provide extra energy for doing heavy physical … Briefly explain the process of aerobic respiration. Aerobic respiration happens in most of the organisms. Answer: Types of Respiration: On the basis of the presence or absence of oxygen, respiration is classified into two types: 1. By breathing faster and deeper, the athlete is giving back oxygen to the muscles which it could not give earlier at the time of running. In general terms, respiration is a chemical process whereas breathing is a chemical process. From prokaryotic bacteria and archaeans to eukaryotic protists, fungi, plants, and animals, all living organisms undergo respiration.Respiration may refer to any of the three elements of the process. There are some organisms such as yeast that can survive in the absence of air. For instance, facultative anaerobes and obligate anaerobes. During heavy exercise, fast running, cycling, walking for many hours or heavy weight lifting, the demand for energy is high. Anaerobic respiration is the type of respiration through which cells can break down sugars to generate energy in the absence of oxygen. Q1 : ...
