Question

Vascular endothelial growth factor (abbreviated VEGF and pronounced "Veg-F") is a peptide signaling molecule related to platelet-derived growth factor. VEGF is important in the formation of the circulatory system because its signaling pathway causes the formation of blood vessels in developing embryos during normal development. Tumors also produce and secrete VEGF, causing nearby blood vessels to branch and grow to form new blood vessels that supply these tumors.

Given what you know about the different kinds of cell signaling and VEGF, which statement is true?

VEGF is a paracrine signaling molecule because it binds to receptors on nearby cells, at the site where new blood vessels are needed.

Answer 1

Answer:

VEGF is a paracrine signaling molecule because it binds to receptors on nearby cells, at the site where new blood vessels are needed.

Explanation:

The platelet derived growth factors utilizes VEGF (Vascular endothelial growth factor) as a signalling molecule. Cell communication between close cells are aided by Paracrine signalling such as VEGF which forms new blood vessels to its close cells by binding with the receptors
