What is glucose?

Glucose 

• Sugar 
• Energy  
• Used to build other molecules

Photosynthesis

• Energy sun -> glucose 
• Water + carbon dioxide -> Oxygen and glucose  
• Symbols? 
• Metabolism example

Metabolism 

• Conversion of substances in a cell into other substances 
• Glucose is formed during photosynthesis
•  During metabolism glucose is converted into different products 

The pathway of glucose

• Breakdown of substances = decomposition
• Breakdown of glucose = body respiration
• Energy release 

Body respiration

• Breakdown of glucose 
• Mitochondria inside cells 
• All cells, all species.
• More in muscles or more in skin?

How do you get oxygen in your body?

Abdominal / belly breathing = diaphragm

The composition of the air we breath

Air is a mixture of several gasses but it consists mainly of Nitrogen (stikstof) and Oxygen. 

Air always contains a bit of water vapor, although the amount of water varies. The composition is therefor often stated for dry air.

What is metabolism?

1. Converting one substance into another
2. Breakdown of glucose
3. Burning reaction

Which species has mitochondria?

1. Plants
2. Animals
3. Bacteria and funghi
4. All of the above

What is the difference of between combustion and body respiration?

What is the main function of the red bloodcells?

1. to transpose oxygen
2. to transport oxygen
3. to transform oxygen

Which part of the brain initiates breathing?

1. brain stem
2. Cerebelum
3. outer brain
4. frontal lobe

Draw the pathway of glucose

  Glucose production -->  glucose breakdown
This drawing includes: 

Chloroplast - mitochondria - metabolism - glucose - photosynthesis- photorespiration 

Work in your notebook

Be prepared to share 

off to work 

the first 10 minutes in silence  

read the basics first 

• basic 1 : 1, 3, 5 and 6
• Basic 2 : 1,3,5,6,7

Today we add

• You can describe how plants use photosynthesis to store energy in glucose 
•  You can explain that breaking down glucose release energy 

• You can explain how respiration works.
