WitrynaSuggest why the drug used to treat schizophrenia is able to bind to the same receptor as dopamine. (1) Suggest why binding of the drug does not lead to production of an action potential. (2) The resting potential of a neurone is maintained by the unequal distribution of ions inside and outside the plasma membrane. WitrynaThese impulses, known as action potentials, occur via very brief changes in the distribution of electrical charge across the cell surface membrane. Action potentials …

Witryna18 gru 2016 · When the electrical impulse travels down the nerve and hits these channels, they open. This flow of ions reestablishes the electrical signal and keeps it traveling down the cell membrane. Certain ion channels are mechanically-gated, meaning they open when the plasma membrane physically moves. WitrynaBiology (Single Science) Variation, homeostasis and micro-organisms. ...

Witryna16 maj 2024 · Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active … WitrynaDefinition.
