Redox Reactions |
When oxidation and reduction happens together |
|
Glycolysis |
The first part of cellular respiration in which glucose is broken down anaerobically in the cytoplasm to two molecules of pyruvate. |
|
Aerobic |
Connected with the presence of oxygen. |
|
Anaerobic |
Connected with the absence of oxygen. |
|
Krebs cycle |
A series of aerobic biochemical reactions in the matrix of the mitochondria, where energy is obtained through oxidation of acetyl coenzyme A. |
|
Link reaction |
The process linking glycolysis with the Krebs cycle, in which hydrogen and carbon dioxide are removed from pyruvate to form acetyl coenzyme A in the mitochondria matrix. |
|
Activation energy |
The energy required to bring about a chemical reaction. The activation energy is lowered by the presence of enzymes. |
|
Coenzymes |
Molecules that some enzymes require in order to function (NAD, FAD, NADP, ETC.). |
|
Electron transport chain |
The mechanism by which the energy of electrons within the hydrogen atoms is converted into a form that cells can use - ATP. |
|
Ribosomes |
Molecules that carry stuff in and out of cells. |
|
Eukaryotic cells |
A cell with a membrane-bound nucleus that contains chromosomes. The cells also possess a variety of other membranous organelles, e.g. mitochondria and endoplasmic reticulum. |
|
Protons |
Positively charged sub-atomic particles found in the nucleus of an atom. |
|
Oxidation-reduction |
A chemical reaction in which electrons are transferred from one substance to another substance. The substance losing electrons is oxidised and the substance gaining the electrons is reduced. |
