Enzymes and digestion
What are enzymes?
What is the optimum temperature for an enzyme?
The temperature at which it becomes denatured.
The temperature at which its activity is greatest.
What happens to enzymes at very high temperatures?
They are killed.
They catalyse lots of different reactions.
They are denatured.
Stomach enzymes work best at:
about pH 2
about pH 7
about pH 12
The correct equation for aerobic respiration is:
carbon dioxide + oxygen = glucose + water
glucose + oxygen = carbon dioxide + water
glucose + carbon dioxide = oxygen + water
