0

Glycolysis yields what?

pyruvate
ATP
reduced cofactor NADH

1

Acetate accounts for how much VFA production?

60-70%

2

Propionate accounts for how much VFA production?

20-30%

3

Butyrate accounts for how much VFA production?

15%

4

What happens during fermentation?

pyruvate is reduced to lactate

5

What part of the production of VFAs can animals do?

they can only do fermentation of pyruvate to lactate.
microbes do all the rest (see appendix 5)

6

Microbes are always doing what?

making lactate and the three VFAs

7

What VFA can be turned into glucose?

propionate

8

What VFA is gluconeogenic?

propionate

9

What are carbs turned into?

100% of carbs turned into VFAs
25% of carbs can be turned into glucose

10

What are the gluconeogenic substrates?

AAs
propionate
lactate
glycerol
