The Hour of Code started as a one-hour introduction to computer science, designed to demystify code, to show that anybody can learn the basics, and to broaden participation in the field of computer science.
Definition. Protein characteristic of the postsynaptic membrane. In a chemical synapse, the postsynaptic membrane is the membrane that receives a signal (binds neurotransmitter) from the presynaptic cell and responds via depolarisation or hyperpolarisation. The postsynaptic membrane is separated from the presynaptic membrane by the synaptic cleft.
1. Cell membranes are based on lipid bilayer. Plasma membranes consist of a lipid bilayer with proteins embedded in the bilayer. The principle lipids are phospholipids. A phospholipid molecules has a hydrophilic head with a phosphate group as part of its structure and two hydrophobic tails.The hydrophobic tails consist of long hydrocarbon chains..
