Answer:
The correct answer is - D. The initiation of a signaling mechanism that leads to the breakdown of glycogen into glucose that can then serve as the fuel for ATP production.
Explanation:
In challenging or dangerous conditions, the body releases a hormone called Epinephering which is a fight or flight hormone that provides a high amount of energy for the particular action.
Epinephrine hormone binds to beta-adrenergic receptors present on muscles and responsible for the rapid conversion of glycogen to glucose-1-phosphate. The glucose results in condition to rapid synthesis of ATP in muscles and thus helps in muscle actions.
When the work performed by the muscular system present in the heart is interrupted by various factors, damage would primarily result from decreased delivery of oxygen.
<h3>What is cardiac muscle?</h3>
It is the muscle tissue of mixed components, which is located exclusively in the walls of the heart.
When the heart is deprived of its normal blood supply, it can cause irreversible tissue damage by disrupting the pathways that carry oxygen to muscle cells.
Therefore, we can conclude that the heart is a vital organ that is made up of specialized tissues and cells, , damage would primarily result from decreased delivery of oxygen.
