Transcript Year 9 Respiration QUICK VERSION

Do now!
Can you write in your planners to finish the
“Planet Patterns” sheet for Friday please?
(Test too don’t forget)
Planet patterns
• Further from the sun the colder they are,
except Venus (greenhouse effect)
• Further from the sun they take longer to
orbit (travel slower and have to go further)
• Inner planets – small, rocky, few moons
• Outer planets – large, mainly gas, lots of
moons
Stick it!
Can you stick the target and word sheets
for the next topic in please?
This lesson
• Know what “fit” means
• Know how exercise affects pulse rate and
breathing rate (and why)
• Know which organs systems work togther
to release energy from food
• Know muscles release energy from food
by aerobic respiration
Fit?
Fit
Being fit means your body can cope with
the activities you need to do

Exercise
Exercise
During exercise you muscle cells need more
energy. They get it from aerobic respiration of
the glucose dissolved in your blood
Glucose + oxygen
Reactants
carbon dioxide + water (+ energy)

During exercise
Your breathing and pulse rate increase
because your cells need more glucose
and oxygen for respiration.
