Anaerobic Respiration Sometimes cells experience conditions with little or no oxygen There are several consequences when there is not enough oxygen available for respiration: There is no final acce...
Oxidative Phosphorylation Oxidative phosphorylation is the last stage of aerobic respiration It takes place at the inner membrane of the mitochondria Several steps occur: Hydrogen atoms are donated...
Aerobic Respiration: Role of NAD and FAD Coenzymes NAD and FAD play a critical role in aerobic respiration When hydrogen atoms become available at different points during respiration NAD and FAD ac...
Aerobic Respiration: Outline of the Krebs Cycle The Krebs cycle (sometimes called the citric acid cycle) consists of a series of enzyme-controlled reactions Acetyl CoA (2C) enters the circular path...
Aerobic Respiration: Entering the Link Reaction The end product of glycolysis is pyruvate Pyruvate contains a substantial amount of chemical energy that can be further utilised in respiration to pr...
Aerobic Respiration: Glycolysis Glycolysis is the first stage of respiration It takes place in the cytoplasm of the cell and involves: Trapping glucose in the cell by phosphorylating the molecule S...
