• 1/3 +0.5 = If you earn this 3 times you get to add 0,5 to one of your biology marks.
• Snitch = You can pick a classmate who also is checked for homework, you earn two V's (having 3 earns you a 1/3 +0,5)

Which substances are made during photosynthesis?

1. Oxygen and Glucose
2. Carbon dioxide and Glucose
3. Water and Oxygen
4. Water and Carbon dioxide

In what organelle is glucose broken down?

Why do mitochondria break down Glucose?

Combustion =

Chemical reaction between a substance (fuel) and oxygen.

OR

The process of burning something

Examples of combustion

What happens during combustion?

• For combustion you need:

        - Fuel = The substance(s) that are burned/combusted

        - Oxygen (O₂)

• During/after combustion you get:

- Energy = Light, heat, movement

- Waste products = The substance(s) that are created 

• As a reaction: Fuel + Oxygen -> Energy + Waste products

What is the fuel used in this combustion?

What types of energy do you get from this combustion?

What waste products will you get?

A cigarette

• What is the fuel?
• Tobacco
• What are the waste products?
• Smoke, ash, etc.
• What types of energy will be released?
• Light, heat
• What is the reaction of this combustion?
• Tobacco + oxygen -> smoke + ash + heat + light

Combustion in organisms

Combustion in organisms = Respiration

Glucose + Oxygen -> Water + Carbon dioxide + Energy

                                        

• Moving
• Heat
• Growth
• etc.
