If the pinsulin receptor, a, example of an integral membrane protein, is cotranslationally inserted into the er membrane with the n-terminus on the cytosolic side of the membrane and the c-terminus in the lumen of the er, which side of the protein would you expect to bind to the ligand, pinsulin, when the protein is found on the cell surface?
(a) n-terminal end of the protein will bind pinsulin
(b) neither will bind to a ligand because both ends of the protein will be extracellular and will compete with each other
(c) c-terminal end of the protein will bind pinsulin
(d) neither will bind to a ligand because both ends of the protein will be cytoplasmic

The correct answer is option C.

Explanation:

As the proteins are produced in the endoplasmic reticulum membrane, they amalgamate with the vesicles and then they are conducted towards the membrane's cell surface where they act as an integral membrane protein.  

The outer end will bind with the ligand and the other one will get attached towards the cytoplasm. Thus, the pinsulin in the given case will combine with the C terminus of the protein.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
