Redox Reactions

When oxidation and reduction happens together


The first part of cellular respiration in which glucose is broken down anaerobically in the cytoplasm to two molecules of pyruvate.


Connected with the presence of oxygen.


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.


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.


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.


Positively charged sub-atomic particles found in the nucleus of an atom.


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.
