Question

1) how does the signal transduction pathway involves to increase the cytosolic Calcium soon after fertilization?

Answer 1

O How does the signal bansdnetic involves to increase the cytosolie after futilization ) pathway calcium soon Answer: Calcium can act in signal tensduction resulting from activation of ion channels or as a second to messenger caused by indirect, signal bansduction pathways such as G protein- couple receptors - Signal transduction pathway involves the binding of extracellular signalling molecules and ligands to receptors treated a on the cell surface ben of insed the cell that triggers events inside the cell to a invoke a response. The response can then alter the cell's metabolism and shape etc. - The's system in stimulated when the Sperm causes the hydrolysis of phosphatidyline sito 4,5- bisphosphate (PIP2) into inositol 1,4,5-triphosphate (Ps) and Diaceh glycnol (DAG) & IP, then binds its receptors in the surface a of the Endoplastie reticulum that induess Ca 2t release and cart is used to communicate and drive intercellular processes aften as a step in signal transduction. Thus, signal transduction pathway involves to increase the cytosole Calcium from afta fertilization
