Answer:
The generation of nitric oxide is done by almost every kind of cell present in the human body, it is one of the essential constituents that plays an important function in maintaining proper health of blood vessels. The nitric oxide acts as a vasodilator, that is, it relaxes the blood vessels' inner muscles, thus making the blood vessels to broaden.
Therefore it can be concluded that nitric oxide enhances the flow of blood and thus reduces the blood pressure. In this manner, nitric oxide helps in tackling the symptoms of conditions like angina.
At the molecular level. the activation of guanylyl cyclase is done by nitric oxide, which further catalyzes the production of cGMP. This cGMP further functions as an intracellular messenger in a pathway that results in the relaxation of the smooth muscles.

60-70%
Explanation:
Carbohydrate is the most important source of energy needed in preparation for prolonged exercise that consumes energy and requires endurance and strength to combat fatigue.
Carbohydrate is a more efficient fuel than fat as carbohydrates are easily broken down to supply an athlete with glucose as readily available energy, and also glycogen that is stored in the muscles, which are used as a fuel source during exercise. Hence, for prolonged heavy exercise, it is recommended that athletes need high carbohydrate consumption of 60-70 percent of their calories to maintain optimal performance.
