1: Physiology: Production of VFAs from Hexose (glucose) class notes Flashcards
1
Q
Acetate accounts for how much VFA production?
A
60-70%
2
Q
Propionate accounts for how much VFA production?
A
20-30%
3
Q
Butyrate accounts for how much VFA production?
A
15%
4
Q
What happens during fermentation?
A
pyruvate is reduced to lactate
5
Q
What part of the production of VFAs can animals do?
A
they can only do fermentation of pyruvate to lactate.
microbes do all the rest (see appendix 5)
6
Q
Microbes are always doing what?
A
making lactate and the three VFAs
7
Q
What VFA can be turned into glucose?
A
propionate
8
Q
What VFA is gluconeogenic?
A
propionate
9
Q
What are carbs turned into?
A
100% of carbs turned into VFAs
25% of carbs can be turned into glucose
10
Q
What are the gluconeogenic substrates?
A
AAs
propionate
lactate
glycerol
11
Q
Glycolysis yields what?
A
pyruvate
ATP
reduced cofactor NADH
