A person who sprints for 45 seconds will obtain most of his or her energy from muscle glycogen.
<h3>Energy metabolism during sprints</h3>
During sprinting or highly intense exercise activities, blood glucose is rapidly consumed. Rapid consumption of blood glucose may breach the blood glucose set point.
In order to maintain blood glucose homeostasis, glucose stored as glycogen in the muscles is converted back to glucose. The glucose is then utilized to produce ATP for the sprint or exercise.
Thus, a person who sprints for 45 seconds will have to obtain most of their energy from the glycogen stored in the muscles.

The correct answer is option d, that is, neurotransmitters.
A neurotransmitter refers to a chemical component, which is discharged at the terminal of a nerve fiber by the introduction of a nerve impulse, and by diffusing across the junction or synapse. It helps in the transfer of the impulse to another muscle fiber, nerve fiber, or some other composition. Acetylcholine is a kind of neurotransmitter, that is, used by neurons in the CNS and the PNS in the control of activities ranging from heart rate and muscle contraction to digestion and memory.
