How does the ligand-gated channel for CFTR work?

1 answer:

5 0

Answer: Ligand-gated channels require a special “key” to unlock their doors, which usually comes in the form of a small molecule.

CFTR is a ligand-gated channel, but it’s an unusual one. Its “key” is ATP, a small molecule that plays a critical role in the storage and release of energy within cells in the body. In addition to binding the ATP, the CFTR channel must snip a phosphate group – one of three “P’s” – off the ATP molecule to function. But when, where and how often this crucial event takes place has remained obscure.

Why does the cell go through elaborate process to convert glucose into carbon dioxide and water?

Tems11 [23]

Cellular Respiration. Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell.

alexandr1967 [171]

High levels of cortisol would normally provide negative feedback to the D)the anterior pituitary and the hypothalamus.

ACTH secretion stimulates the discharge of glucocorticoids (cortisol), mineralocorticoids (aldosterone), and androgen from the adrenal cortex.

Corticotropin-liberating hormone (CRH) is launched from the hypothalamus, which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.

Cortisol increases blood sugar by way of releasing stored glucose, at the same time as insulin lowers blood sugar. Having chronically high cortisol stages can result in continual high blood sugar (hyperglycemia). this can purpose type 2 diabetes.
