Question

Jamie is running a race this afternoon. He eats breakfast to make sure that he can reach the finish line because food provides the Energy his Cells need to complete any activity. What kind of Energy is stored in food?

Answer 1

The energy stored in food that Jamie eats for running a race is chemical energy. This energy is released when the body digests and breaks down nutrients from food, which is then used or stored as glycogen for physical activity.

Step-by-step explanation:

The kind of energy stored in food which Jamie consumes to run a race is known as chemical energy. This energy is locked within the chemical bonds of the nutrients found in food, such as carbohydrates, proteins, and lipids. When Jamie's body digests this food, it breaks down these molecules and releases energy that can be used for vital functions or activities like running.

During the absorptive state, Jamie's body is in the fed state, digesting food and absorbing nutrients. Sugar and amino acids from digested food enter the bloodstream, while fats enter the lymphatic system and are transported to various cells for utilization or storage as energy. This is crucial as the brain and other organs require a continuous supply of glucose, which can be provided through the stored glycogen in the muscles, especially important for endurance activities like marathons.

Overall, the ingestion and breakdown of food allow Jamie to convert chemical energy from food into the work needed to run, maintain body temperature, or store in fatty tissue as chemical energy for later use.
