thus slowing down the respiration process.In bacteria or other microorganisms high temperatures might kill them.Adaptation:Enzymes after some time get adapted to different temperature. This is a part of evolution.Oxygen: The presence of oxygen hinders anaerobic respiration in higher level organisms. However many microorganisms are not affected by the presence or absence of oxygen as they have only anaerobic respiration.The importance of anaerobic respiration is that is a substitute for aerobic respiration. This is used in many industries. E.g. dairy industry.Conclusion:The law of conservation of energy states that energy can neither be destroyed nor created and to confirm to it we have these biological chemical processes, which are interrelated. The end product of photosynthesis is the raw material of respiration. The byproducts of respiration are used in photosynthesis.
