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.
The nuclear membrane consists of two lipid bilayers âthe inner nuclear membrane, and the outer nuclear membrane. The space between the membranes is called the perinuclear space, a region contiguous with the lumen (inside) of the endoplasmic reticulum. It is usually about 20â40 nm wide.
