Excitatory postsynaptic potential (EPSP)

During this potential, excitatory transmitter opens Na+ or Ca2+ channels in the postsynaptic membrane, producing an inward current & the excitability of the neuron to other stimuli is increased

#Unit 1. Molecules and their Interaction Relevant to Biology

Intrinsically disordered proteins lack a hydrophobic core, and have high densities of charged amino acid residues such as Lys, Arg, and Glu. Pro residues are also prominent, as they tend to disrupt ordered structures.
