Chapter 2.3, Problem 1AWYL
Summary Introduction
To review:
The reason behind feeling hot during and after exercise.
Introduction:
Any form of work requires energy. Energy can be defined as the potential or capacity of an object or organism to do work. Energy can be possessed by both moving as well as still objects. There are many forms of energy, such aspotential, mechanical,

Directions: Complete the paragraph below to
explain why your body gets warm during a
workout.
When you workout, your cells need
for muscle contraction. In order
to get this, your body will carry out a process
called
During this process,
(from food) is broken down in
the presence of
to make the
usable form of energy for cells, called
This process converts
energy from the bonds of food
molecules into energy that is
(potential energy) in ATP molecules. The
process also releases
(thermal)
energy, which is why you feel warm. Your body
carries out this amazing process to fuel your
workouts!
