What is it called when yeast respires anaerobically?
Fermentation.
1 of 8
Word equation for fermentation.
Glucose -> ethanol + carbon dioxide (+ energy)
2 of 8
How does the temperature affect the growth rate of yeast?
Yeast produces faster when it's warmer (growth rates double for every 10*c riseuntill optimum temp is reached) If too hot, then yeast dies.
3 of 8
How does glucose affect the growth rate of yeast?
More food (glucose), the faster the yeast reproduces.
4 of 8
How do waste products affect the growth rate of yeast?
A build up of waste product (ethanol) eventually kills the yeast, slowing down the growth rate.
5 of 8
How does the pH affect the growth rate of yeast?
Has to be around the optimum pH of 7, a lower or higher pH will stop the enzymes on the yeast from working.
6 of 8
How does the addition of oxygen change the respiration of yeast?
Releases more energy, reproduces faster when respiring aerobically.
7 of 8
How can waste water be cleaned with yeast?
To get rid of sugary water
