What Does The Signaling Protein Vegf Stimulate

Question: Stage 1: Cell Reception

Answer: target cell detects signal molecule which binds to a (receptor) protein on the cell membrane or cytosol of the cell

Question: How do blood vessels grow?

Answer: Stimulated endothelial cell undergoes mitosis and migration.

Question: Ligand

Answer: signalling molecule- A chemical released by a cell to have an impact on a target cell when it binds causing a change in shape of the receptor

Question: Stage 3: Cellular Response

Answer: -The cellular reaction to the transduction of the original signal. EG: gene activation, Protein synthesis, altered metabolism, make cells more permeable, breakdown of substances

Question: Membrane Receptor Proteins

Answer: Extracellular transmembrane receptors, for hydrophillic signalling molecules that have a binding site on the membrane
