Yeast Fermentation Experiment

1. In the yeast experiment, we supplied yeast with a supply of the six-carbon sugar (name). In glycolysis, the six carbons are divided, and the

resulting 3-carbon molecules are called

aerobic respiration if the conditions are suitable.

that molecule feeds into

2. We wanted to test fermentation in the presence (and absence) of the inhibitor and we quantified the amount of fermentation by observing which was produced.

3. Name two sources where we encounter NaF in everyday life.

4. In aerobic respiration, more energy is produced in the form of

than in

anaerobic respiration. Aerobic respiration will not happen in the absence of but anaerobic respiration can occur under such condition.

5. What gas is produced as a waste product in anaerobic respiration? What additional toxic waste product is produced in yeast?

6. In our experiment, which tubes produced the least fermentation? Please answer by describing two specific conditions that caused reduced growth:

condition 1:

Enzymes/Spectrophotometer/Standard Curve

condition 2:
