Solution
Elevated adrenaline levels will inactivate Glycogen synthesis in the liver.
Here's a step-by-step explanation:
-
Adrenaline, also known as epinephrine, is a hormone that is released in response to stress or danger. It prepares the body for a 'fight or flight' response by increasing heart rate, blood pressure, and energy production.
-
One of the ways adrenaline increases energy production is by stimulating the breakdown of glycogen, a stored form of glucose, into glucose that can be used for energy.
-
This process, known as glycogenolysis, takes place in both the liver and the muscles. In the liver, the glucose can be released into the bloodstream to be used by other cells. In the muscles, the glucose is used directly for energy.
-
At the same time, adrenaline inhibits the synthesis of new glycogen in the liver. This is because it would be counterproductive to break down glycogen for energy while also trying to store energy as glycogen.
-
Therefore, elevated adrenaline levels will inactivate glycogen synthesis in the liver.
So, the correct answer is "Glycogen synthesis in the liver".
