Respiration is the mechanism by which the nutrients we absorb are converted into usable energy. The cell, as we know, is the structural and functional unit of life, and to perform its functions, each cell needs energy. Respiratory that occurs at the smallest level of our body is also called cellular respiration. The method ensures that each cell perfectly performs its role.
- During respiration, the temperature increases.
- Respiration may be physiological and cellular.
- In individual cells, cellular respiration occurs, whereas physiological respiration is a bulk operation.
- Cellular respiration occurs in the cells and through a series of metabolic reactions that transform biochemical energy from the nutrients into ATP and extract waste. Such responses are catabolic reactions in the process that produce energy and heat.
