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
