Answer:
The answer is (1) It initiates a cascade.
Explanation:
Signal transduction pathways regulate many important cellular functions such as growth, differentiation, metabolism, and survival. Many of these signaling pathways are altered in human cancer.
<em>Receptor tyrosine kinases </em>are cell surface receptors that play a role in the signaling pathways governing cellular processes of metabolism, intercellular communications, differentiation, survival, and proliferation.
They bind to their corresponding growth factors, triggering the downstream signaling cascade.
