Respiration in micro-organisms is the process of releasing energy from food. There are two ways of doing so: Aerobic respiration occurs in the presence of oxygen and produces ATP from the complete oxidation of carbohydrates or fatty acids. Anaerobic respiration involves incomplete oxidation in the absence of oxygen. No matter the method, bacterial respiration is thought of as a continuous process that releases energy continuously. However, the word "continuous" is ambiguous.
My question is:
- Is the respiration continuous without rest (e.g. DC signal) where the bacteria are releasing energy at every stage of the respiration process.
- Is it alternating (Like human breathing (inhale & exhale)) where the bacterial cell produces energy during one stage of the respiration stages and takes a rest in a periodic rhythm (e.g. AC signal) before releasing energy again?
