Effect of Temperature & Substrate Concentration A redox indicator is a substance that changes colour when it is reduced or oxidised DCPIP and methylene blue are redox indicators They are used t...
Anaerobic Adaptations of Rice Flooding is a major problem when growing crops As water rises and it covers the different parts of a plant it can create problems: Plant roots don’t get the oxygen the...
Aerobic & Anaerobic Respiration In cells there is a much greater energy yield from respiration in aerobic conditions than in anaerobic conditions In anaerobic respiration glucose is only partia...
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...
