Respuesta :
A) When given intravenously, epinephrine raises coronary artery pressure and increases coronary blood flow.
B) In the liver, adrenaline accelerates glycogen breakdown to glucose, resulting in an increase in blood glucose levels.
What is meant by Epinephrine ?
Adrenaline, often known as epinephrine, is a hormone and medicine that regulates visceral functions (e.g., respiration). It appears as a white microcrystalline particle. Adrenaline is generally created by the adrenal glands and a small number of neurons in the medulla oblongata. It aids in the fight-or-flight response by increasing blood flow to muscles, cardiac output via the SA node, pupil dilation reaction, and blood sugar level. It accomplishes this by attaching to alpha and beta receptors. It is found in numerous species, including humans, as well as some single-celled creatures. It has also been isolated from the plant Scoparia dulcis, which grows in Northern Vietnam.
Epinephrine can assist raise blood pressure and possibly restart the heart.
Cardiopulmonary resuscitation (CPR) with epinephrine, reversal cardiac arrest The effects of alpha-1-adrenoceptor agonists are responsible for the action.

The complete question is:
"Epinephrine signaling leads to a decrease in the rate of glycolysis in the liver, but an increase in the rate of glycolysis in the muscle (particularly the heart muscle). A). Explain the physiological basis (general function within the organism) for these differences. (why would it benefit the organism to have these different effects ?) B). Explain the biochemical basis of these differences. Propose two (there are more than 2 options, but any 2 reasonable approaches will count) mechanisms to accomplish these differences. (how is the organism able to get different effects in different tissues from the same hormone?)"
