1. Cellular Respiration
Chapter 2: Lesson 2
Page 50

2. What Happens During Cellular Respiration?
You eat
Your body breaks food down
Sugar in food is released in the form of glucose (Glucose = C6H12O6)
CELLULAR RESPIRATION is the process by which cells obtain energy from glucose.

3. Find the key!!!
During cellular respiration, cells break down glucose and other molecules from food in the presence of oxygen, releasing energy.

4. Storing and Releasing Energy
Your body stores and uses energy
When you eat, you add to your body’s energy savings account
When cells need energy, they “withdraw” it by breaking down glucose through cellular respiration.
See Figure 1, Page 51

5. Cellular Respiration – color the last three energy scales to show how the hiker’s energy changes.
Getting Energy
How does the hiker's energy and breathing rate change as she climbs?

6. Cellular Respiration Getting Energy
How does the hiker's energy and breathing rate change as she climbs?

7. Breathing and Respiration
What is the difference?
Breathing: moving air in and out of your lungs
Breathing: brings oxygen into your lungs.
Breathing: removes waste products of cellular respiration.
WRITE THIS:
RESPIRATION is using the oxygen to create energy.

8. #2. Challenge: How do you think the hiker’s breathing rate changes as she climbs?
The hiker would breathe faster and deeper in order to get more oxygen needed to make more energy in cells.

11. The Two Stages of Cellular Respiration - Page 52
The first stage takes place in the cytoplasm
Molecules of glucose are broken down into smaller molecules
Small amount of energy released
The second stage takes place in the mitochondria
Molecules of glucose are broken down even smaller
Requires oxygen and releases LOTS of energy

14. The Cellular Respiration Equation
C6H12O6 + 6O CO2 + 6H2O + ENERGY
Raw materials: glucose and oxygen
You get glucose from food & oxygen from air.
Products: Carbon dioxide, water and energy

15. Comparing Two Energy Processes
Photosynthesis and cellular respiration can be thought of as opposite processes.
See Figure 3. Try to figure out what goes in the blanks. Words in the word bank can be used more than once.
