Show Answer
Correct Answer – A
Ans: A. Insulin
Insulin acts on specific receptors located on the cell membrane of practically every cell, but their density depends on the cell type: liver and fat cells are very rich.
The insulin receptor is a receptor tyrosine kinase (RTK) which is a heterotetrametric glycoprotein consisting of 2 extracellular α and 2 transmembrane β subunits linked together by disulfide bonds.
