Aerobic respiration in yeast Essay - 738 Words.
Aerobic respiration is a very important process, not only in the human body, but also in the bodies of other organisms. If this process were to stop working, their would be no fresh supply of oxygen to our cells, and oxygen is the final elecron acceptor. Without aerobic respiration we would have not have sufficient energy for survival.

In cyanobacteria, oxygen is potentially consumed through aerobic respiration and two light-dependent reactions, the oxygenase activity of RubisCO (photorespiration) and the photosynthetic reduction of O 2, termed pseudocyclic photophosphorylation or the Mehler reaction (Box 35.2).In contrast to terrestrial C3 plants, which have relatively high rates of photorespiration, photorespiration of.
Cellular respiration by itself refers to the process of drawing energy from food and organic molecules for use. This is done by several reactions that are dependent upon each other. Similar to breathing, whereas as humans inhale oxygen, and exhale carbon dioxide, the process of cellular respiration is the exchange of oxygen to help break down the fuel which is defined as an aerobic process.
Anaerobic respiration Aerobic respiration: 1. It is the normal mode of respiration in some parasitic worms and microorganisms such as bacteria, mould etc. 1. Aerobic respiration is the normal mode of respiration of plants and animals. 2. No exchange of gases occurs. 2. It involves exchange of gases between the organism and the environment. 3.
In aerobic respiration, oxygen gas is the final electron acceptor in the electron transport chain where the majority of the ATP molecules is produced. Also, glucose is not fully broken down in anaerobic respiration, so there is still chemical energy that is not released in the bonds of the lactic acid or ethanol.
