1.2 - Respiration and combustion
Energy

Where in your body is energy needed?

And what for?

Slide 9 - Slide

Combustion (= verbranding)
Specific form of combustion in our cells = cellular respiration

Cellular respiration: Glucose is broken down to energy and water


Slide 10 - Slide

Cellular respiration
Glucose + oxygen -> water + carbondioxide + energy
