Lesson Plan
Lesson Plan Starter - Think Pair share - 1 min to think about
the question, 2min to discus it with partner 2min to share with the
class Met rate Activity Fat to muscle Inherited factors
What do know about Respiration?Write everything you remember in
you book about respiration
You have 2 minutes
Learning ObjectivesAll will be able to Define metabolic
rate.
Most will be able to describe what affects metabolic rate and
the benefits of regular exercise.
Some will be able to describe the relationships between food
intake, exercise and fitness.

Metabolic rate What is Metabolic rate?Humans are made of lots of
cells.
Each cell carries out lots of chemical reactions including
respiration (which releases energy from food) and making
proteins.
Together, these chemical reactions are known as the
metabolism.
The rate at which these chemical reactions go on is the
metabolic rate.
Think Pair Share Why two people sitting will have different
metabolic rates and use up different amounts of energy?
Starter - Energy needsYour metabolic rate is the rate at which
chemical reactions take place in your cells.
EndWhy different energy needs??genetic factorsMen usually have
faster metabolic rates than women. Why?Muscle cells need more
energyThe less exercise you take and the warmer it is, the less
food you need. If you exercise your metabolic rate stays high for
some time after you have finished.
Metabolic rateThe rate at which all the chemical reactions in
the cells of the body are carried out (the metabolic rate) varies
depending upon:
- amount of activity you do (exercise and your job)
proportion of muscle to fat (regular exercise builds muscle)
- inherited factors
Metabolic rateTask 1 - Fill in the gapsChemical reactions in
cells are collectively called _____________.The rate at which all
the chemical reactions are carried out is your ______________.Your
metabolic rate varies with:- the amount of __________ you do- the
proportion of muscle to ______ in your body - and may also depend
on ___________ factors
Learning ObjectivesAll will be able to Define what metabolism
and metabolic rate is.
Most will be able to describe what affects metabolic rate and
the benefits of regular exercise.
Some will be able to describe the relationships between food
intake, exercise and fitness.

Metabolic rate
What happens when you exerciseYour muscles contract more to move
your limbs.However, muscles need energy to contract.So, muscle
cells respire more to release more energy from glucose.To provide
this glucose, you need to eat more food.
Metabolic rate and exerciseTask 2 - Fill in the gapsWhen you
exercise:Your ___________ contract more to move your limbs.Muscles
need __________ to contract.So muscle cells need to __________ more
to release more energy from glucose.To provide the energy, you need
to eat more _________.____________ increases the amount of energy
expended by the body.Proportion of muscle to fatIf you have more
muscle and less fat, then your body has a higher metabolic rate
than someone who has less muscle and more fat. Males have more
muscle and less fat in their bodies; females have less muscle and
more fat. This is largely determined by genes.Most males therefore
need to eat more than most females.Females can increase their
muscle mass by exercise.Effect of exercise on Metabolic rateTask 3
- Fill in the gapsFat cells store fat. They are __________ and have
a low rate of ___________ so they do not use their stored
fat._________ cells are active. They need ________ from respiration
to contract. Their rate of respiration is ______.If you have more
muscle and less fat then your body has a ________ metabolic rate
than someone who has less muscle and _______ fat. You need to eat
_______ food to supply the energy needed for the muscle
cells.Learning ObjectivesAll will be able to Define what metabolism
and metabolic rate is.
Most will be able to describe what affects metabolic rate and
the benefits of regular exercise.
Some will be able to describe the relationships between food
intake, exercise and fitness.

Other factors that affect Metabolic rate Age - the younger you
are the higher your metabolic rate is.Inherited factors - such as
high the taller you are the higher you metabolic rate is People who
are ill e.g. underactive thyroid may have a higher metabolic
ratePeople who are overweight have a higher metabolic rate as the
body is larger so it needs to work harderWhat if..What if you were
a teenager that didnt exercise regularly what would be the
consequences?3 mins
