DO I HAVE ENOUGH ENERGY
Learning Objectives:
•To describe how the body uses energy
•To explain what is meant by respiration
•Analyse the energy requirements of different people
Starter:
The next slide has different athletes – you need to rank
them from which you think burns the most calories to the least

Using Energy
Where do we get our energy from?
When you are walking on a cold day what is some of the energy in your body
being used for?
When you are sleeping what is some of the energy used for?

Food labels
•Energy is measured in units known as kilojoules (kJ).
•Energy is also measured in calories (kcal).
•1 calorie = 4.2 kJ

Energy and nutrients
Food and drinks provide us with different amounts of energy because of the variety of nutrients they contain.
1g protein provides 17kJ (4 kcal).
1g carbohydrate provides 16kJ (3.75 kcal).
1g fat provides 37kJ (9 kcal).

Activity
Look at your food labels. In groups discuss:
oHOW MUCH ENERGY IS IN EACH ONE?
oHOW MUCH SUGAR (CARBOHYDRATES) AND FAT IS IN IT?
oWHAT TIME OF THE DAY SHOULD YOU EAT THIS FOOD?
oDO YOU THINK YOU WOULD HAVE TO DO MUCH EXERCISE AFTER EATING THIS FOOD?

This type of respiration is called aerobic respiration because energy is released with oxygen.
Respiration is the process that the body uses to release energy from digested food (glucose):
What is respiration?
carbondioxideglucose oxygen water energy
How do the glucose and oxygen needed for aerobic respiration get to the all the body’s cells?
