Invisible Gases, Life Science, Lab 09,

1. Tracking Invisible
Gases

2. Cellular Respiration

3. Key Objectives:
 The student will:
– Investigate and understand the
physical and chemical process of
cellular respiration and its
importance to plant and animal
life

4. Key Objectives:
 The student will:
– Use words or chemical equations
to compare and contrast the
processes of photosynthesis and
respiration in terms of raw
materials required, products
produced and cellular organelles
involved

5. Cellular Respiration
 The process in which all living
things including plants obtain
energy stored in food

6. Cellular Respiration Diagram

7. Essential Learnings
 All livings turn food into energy
through a process called
cellular respiration

8. Essential Learnings
 Cellular respiration is a
chemical process that occurs in
an organelle called the
mitochondria of each cell of a
living organism

9. Essential Learnings
 In the mitochondria, glucose
molecules are combined with
Oxygen to release energy and
produce Carbon Dioxide (CO2)
and Water (H2O)

10. The Mitochondria
 Often called the
power source of the
cell

11. Inside the Mitochondria

12. Essential Learnings
 Photosynthesis provides food
and oxygen necessary for
cellular respiration of all plants
and animals

13. Photosynthesis

14. Essential Learnings
 During respiration Oxygen is
used and Carbon Dioxide is
given off to the environment
where it becomes available for
producers to use again

15. Essential Learnings
 Matter, in this case Oxygen and
Carbon Dioxide is recycled
 This is known as The Oxygen
Carbon Dioxide Cycle
– Part of the Carbon Cycle

16. The Carbon Dioxide -Oxygen Cycle
