Answer:
G proteins. (Ans. B)
Explanation:
Metabotropic receptors are also called neurotransmitter receptor, they are indirectly linked with ions channels through the signal introductions mechanism on the plasma membrane of the cell & activating G-proteins. The Metabotropic receptor is activated by specific neurotransmitters (is known as a chemical messenger which delivers a signal across a chemical synapse, from 1 nerve cell to another target neuron).
G protein which is also called guanine nucleotide-binding proteins, that behaves as molecular switches inside the cells & they are involved in delivering the signals from stimuli outside the cell to its inside.
This means that certain cells are made by the body for different reasons. For instance, muscular cells are made for muscles, bone for bones, etc.
Hope this helped!
