Epinephrine is a hormone that regulates cellular energy metabolism to break down glycogen into glucose. The signal transduction pathway involves the production of cAMP. If caffeine blocks the activity of cAMP, what would happen to the signal transduction pathway?

The signaling pathway will amplify and produce more glucose.
The signaling pathway will conform to bind to the receptor cells.
The downstream components will be altered and ultimately affect production of glucose.
The downstream components will function normally.

Answers

Answer: The downstream components will be altered and ultimately affect production of glucose.

Explanation: Epinephrine is a hormone that belongs to a class of biomolecules called catecholamines. When it reaches the target cell it binds to a receptor that is connected to an enzyme called adenylate cyclase that converts ATP into cAMP(cyclic adenosine monophosphate). cAMP plays an important role in the phosphorylation of proteins which alters their activity. In this case the activity of the enzyme that hydrolyses glycogen to glucose. When caffeine blocks the activity of cAMP it ultimately inhibits the action of the downstream components.

If caffeine blocks the activity of cAMP, then in the signal transduction pathway the downstream components will be altered and ultimately affect the production of glucose. Thus, the correct option is C.

What is Epinephrine?

Epinephrine is also known as adrenaline. It is a hormone which belongs to a class of biomolecules called catecholamines. When this hormone reaches the target cell it binds to a receptor present on the cell that is connected to an enzyme called the adenylate cyclase which converts ATP into cAMP (cyclic adenosine monophosphate).

cAMP plays an important role in the phosphorylation of proteins in the cell which alters their activity. In this case, the activity of the enzyme that hydrolyses glycogen to glucose.

A patient is given antihistamines due to an allergic reaction where vascular permeability is increased, causing watery eyes. Which of the following describes how antihistamines affect a signal transduction pathway?

Antihistamines block histamine from binding to the appropriate receptor.
Antihistamines reduce histamine in the blood by binding to and destroying it.
Antihistamines reduce the amount of histamine in the bloodstream by binding to and inactivating histamine.
Antihistamines produce a second messenger that interrupts and reverses the direction of the signaling pathway.

Answers

Answer:

Antihistamines affect a signal transduction pathway by blocking histamine from binding to the appropriate receptor (First option).

Explanation:

Antihistamines are a group of drugs used in allergic reactions mediated by the immune system. Specifically, antihistamines are competitive inhibitors of histamine binding to its specific receptor, the histamine H1 receptor.

Histamine is an inflammatory mediator, being one of the substances of the humoral immune response. It is secreted by mast cells and is responsible for the production of allergic effects, such as nasal congestion, sneezing, skin rash, and red, watery eyes. Antihistamines block histamine from binding to the appropriate receptor, preventing these effects.

The other options are not correct, because they do not correspond to the effects of antihistamines, that is, it does not bind to histamine, destroy it or render it inactive..
