Question

EGF signals are enhanced by proton pumps that reduce the pH in endosomes carrying the endocytosed EGF receptor.

A) True   

B) False

Answer 1

EGF is an important polypeptide that is crucial for the differentiation as well as growth in the organism bond with the receptor. This is very low molecular weight protein, which is six-kilo Dalton and composed of fifty-three amino acids attached through sulfide bond. EGF controls the regulation of its receptor in the endosome. ATPase, proton pump that act upon lower pH and eventually lead the depredation through lysosome, and these battery of events take place due to EGF signals.. Hence, the given statement is “True”.
