E)G proteins

Question

Quizplus · Accepted Answer

Membrane receptors are proteins located on the cell surface that can receive signals from outside the cell and transmit them into the cell, converting an extracellular signal into an intracellular signal. They can act as ion channels or enzymes that initiate signal transduction pathways. Second messengers, scaffolds, adapter proteins, and G proteins are all involved in intracellular signaling but do not directly convert extracellular signals into intracellular signals.
