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...
The Four Stages in Aerobic Respiration Glucose is the main respiratory substrate used by cells Aerobic respiration is the process of breaking down a respiratory substrate in order to produce ATP us...
Structure & Function of the Mitochondria Mitochondria are rod-shaped organelles 0.5 - 1.0 µm in diameter They are the site of aerobic respiration in eukaryotic cells The function of mitochondri...
Investigating RQs Respirometers are used to measure and investigate the rate of oxygen consumption during respiration in organisms They can also be used to calculate respiratory quotients The exper...
Respiratory Quotient (RQ) The respiratory quotient (RQ) is: the ratio of carbon dioxide molecules produced to oxygen molecules taken in during respiration RQ = CO2 / O2 The formula for the Respirat...
