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 lac operon, which stands for Lactose operon is known as an inducible system. It is the an operon required for the transport and metabolism of lactose some enteric bacteria (Echerichia coli for example). The Lac operon is only activated in the presence of a key molecule. The key molecule is lactose.
From the given options the following best describes the Lac operon:
D. The repressor is freed from the operator when lactose is present.
