Motor neurone nerve cell and synapses

Motor neurone and synapses. Computer graphic of a motor neurone and synapses (glowing yellow bulges, at lower centre). The cell body is at centre. It has a central nucleus (red circle) and axons (upper left, lower centre and lower right) for transmitting information and dendrites (branching processes) for receiving information. The motor neurone cell transmits and receives impulses (messages) to and from other nerve cells at junctions called synapses. The impulses are passed across the synapses by chemicals called neurotransmitters. Motor neurones transmit impulses from the brain to muscles or glands in order to inhibit or excite a response

Art of cytochrome oxidase enzyme

Cytochrome oxidase enzyme. Illustration of a model of the enzyme cytochrome oxidase, important in respiration. Cytochromes are widely distributed respiratory catalysts concerned with the electron transport chain of living cells. They are proteins often regarded as enzymes. Here, a cytochrome oxidase molecule (green) is located on a membrane such as in mitochondria, chloroplasts and endo- plasmic reticulum. In the biochemical pathway of respiration, cytochrome oxidase has an iron- porphyrin group which uses atmospheric oxygen to convert iron Fe2+ to Fe3+. With this electron transfer, the energy carrier ATP is produced
