Match the membrane protein with its function.
-receptors
A)transfer signals from the extracellular environment to the cytoplasm of the cell
B)form cell-to-cell connections
C)bind to molecules to facilitate entry to or exit from the cell
D)ligands bind to these proteins and are changed by the protein

Question

Quizplus · Accepted Answer

Receptors bind to specific molecules, such as hormones or neurotransmitters, on the cell surface and transfer signals from the extracellular environment to the cytoplasm of the cell, which in turn triggers a cellular response.

Answer: C
 Transport proteins bind to specific molecules, such as ions or nutrients, on the cell surface and facilitate entry to or exit from the cell by transporting them across the membrane.

Answer: D
 Ligand-gated ion channels are protein channels that open or close in response to the binding of specific molecules, called ligands, to the protein. This results in a change in the permeability of the membrane to ions, which can change the membrane potential and trigger a cellular response.
