Questions from students

Q: I would like to ask:

1. The major difference between aerobic and anaerobic ( and also
fermentation)respiration is that the aerobic respiration use external electron
acceptor e.g. oexgyen or other chemicals, while the latter 2 reactions use
internal acceptor?

2. Is incubation time equal to latent period?

3. Mold and yeast are both fungi and so both have cell walls. Do they have very
similar heat resistance?

A: 
  1. aerobic--air, i.e. oxygen; anaerobic, no air, i.e. no oxygen. Fermentation--no external electron acceptor.
  2. No
  3. Yes, similar.  But there are many different kinds of fungi and yeasts. And we have to consider the differences between vegetative cells and spores.
 Q: Are the pages 93-117 in the notes included in the exam?

A: Yes
