Slide 2 - Tekstslide

What do we call respiration that uses oxygen?
A
Normal respiration
B
Super respiration
C
Aerobic respiration
D
Respiration

Slide 3 - Quizvraag

Types of respiration
-Areobic respiration (with oxygen)
-Anaerobic respiration (without oxygen)

Slide 4 - Tekstslide

Fermentation by yeast
Yeast can respire with or without oxygen
When yeast respires without oxygen --> fermentation

Glucose -> alcohol + carbon dioxide + energy

What could fermentation be used for? 

Slide 5 - Tekstslide

Anaerobic respiration by muscles
Glucose breaks down into lactic acid
This can slowly poison your muscles 

Glucose -> Lactic acid + energy

Extra oxygen breaks down lactic acid
This extra oxygen that is needed is called: Oxygen debt

Slide 6 - Tekstslide

Energy produced 

Slide 7 - Tekstslide

Fermentation
Anaerobic respiration
by muscles
Aerobic respiration

Glucose -> Lactic acid + energy
Glucose + oxygen -> CO2 + water + energy
Glucose -> alchohol + CO2 + energy

Slide 8 - Sleepvraag

Fermentation
Anaerobic respiration
by muscles
Aerobic respiration

Lots of energy produced
Almost no energy produced
Some energy produced

Slide 9 - Sleepvraag

Slide 10 - Video

Hyperventilation
-Reduction in CO2 
-Low CO2:
 narrowing blood vessels that supply blood to the brain (dizzy)

Hypoventilation -> Reduction O2

Breathing signal to brain -> too much CO2 in the blood
