If the pinsulin receptor, a, example of an integral membrane protein, is cotranslationally inserted into the ER membrane with th
e 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
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.
Try to search up each one, and match the image with the one. Im sorry this isnt the answer but thats how you find it. And with number 6 and 4 search it up on google and you will get it.
The defecation reflex involves two postive feedback loops. these loops are the stretch receptors in the rectal walls and the sacral parasympathetic system. Defecation reflex empties the rectum by peristaltic movements push fecal matter from the sigmoid colon into the rectum. Then this distension of the rectal walls stimulates stretch receptors which results in defecation.
Each of a Number of small areas of habitat, typically of one square meter, selected at random to act as samples for assessing the local distribution of plants or animals.
The ozone layer is a layer in the atmosphere which provides a barrier between harmful UV rays and the Earth. However, pollution is quickly depleting the layer which in turn creates a higher risk of skin cancers and other conditions caused by harmful UV rays.
