 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.
