Unit 1: combustion and breathing

Planning for today

• Intro 
• BS. 1.1  Metabolism
• Make exercises 
  
• Check up 

At the end of lesson 

... you can explain how plants hold energy in glucose during photosynthesis.

... you can explain that breaking down glucose releases energy.

Maarten van der Weijden

 195 km in 4 days!

• Where did he get the energy from?
• What role did the respiratory system play?

Sunlight energy

Where do we get energy from?

make notes

Where do we get energy from?

• water + CO2+ sunlight → glucose + O2
  

• converting substances into other substances = metabolism

make notes

How does energy come free?

Glucose can be broken down. This happens in the mitochondria.​

Important! Both plant and Animal Cells have mitochondria. 

​Energy comes free when glucose is broken down. This process is called combustion.

​

Now get to work

• Make exercise 4 + 6 t/m 9 
• Exercise 4 in your notebook

What you don't finish will be homework!

Answer the questions below:

1. Explain how photosynthesis works and how plants store energy in glucose. 

2. Explain how energy is released when glucose is broken down.
