HOPE 1

2. The body needs energy to function, even
during sleep and rest. During exercise, energy
must be produced faster rate as compared to
its resting state.
With different forms of activity, muscle are
used, and the heart compensates be beating
faster to deliver oxygen to the whole body.

3. Energy comes from what we eat which are in
the forms of:
1. Carbohydrates – our muscles live and
and store carbohydrates in what is known
as “ Glycogen”.
GLYCOGEN is used as fuel by the body when
it is broken down as glucose.

4. 2. Fat – fat is stored under our skin or
dispose tissue. It serves as insulation for the
body to prevent heat loss.
Fat or Triglyceride, serves as fuel too when it
is broken down into two types of molecules
– glycerol and fatty acid

5. 3. Protein – one of our building blocks. This
is used for the repair and growth of body
tissue.
Energy can also be produced when protein is
broken down but this only happens in
prolonged endurance events such as
marathons.
