short powerpoint outlining respiration and referring to the new Tom Cruise movie 'Mission impossible'

1. Cellular
Respiration
Topics 3.7 and 8.1

2. Respiration
What is the purpose of respiration?
A) To help you breathe
B) To allow you to cool down after exercise
C) To release energy from sugars
D) To digest food

3. Respiration – a slow fire?

4. ATP – the energy store
• Q) HOW is the energy stored?
• A) In a molecule called ATP (Adenosine Triphosphate)
-To get the energy back you remove a phosphate group to form ADP
(Adenosine Diphosphate)

5. ATP synthesis

6. Oxygen present?
Aerobic respiration occurs
• Aerobic respiration releases a relatively large amount of energy
• C6H12O6 + O2  CO2 + H2O + ATP
• To have aerobic respiration, the delivery of oxygen by the
cardio vascular system must be enough to keep up with the
demand.

7. No oxygen present?
Anaerobic respiration.
Releases less energy, so less ATP
1. Producing alcohol eg. Yeast to make
bread, beer or wine
2. Producing lactate
eg. Human muscle cells during
hard use
• ATP production limited.

8. Aerobic vs Anaerobic exercise
Some exercises require
anaerobic respitation to
maximise muscle power
There is a limit to how much
lactate the muscle tissue can
stand.

9. At cinemas now
MISSION IMPOSSIBLE 5: ROGUE NATION

10. The 3 minute swim – what
happens inside his cells?
Ethan needs to swim
For 3 minutes to in a
Water flooded security
Storage database.
-He cannot use an
Oxygen tank
-He succeeds in
his mission
-But passes out before
he can escape
-He is rescued by British spy Ilsa Faust
