Glucose Metabolism Step Two

Question 1

First step in step two

Answer 1

Fructose-1,6-Phos is cleaved by an aldolase to two Glyceraldehyde-3-Phosphates

GAP is interconverted to Dihydroxyacetone Posphate (DHAP)

Question 2

Under what conditions is DHAP favored

Answer 2

High energy: Low ATP, NAD, but HIGH NADH

G3P–> DHAP –> Glycerol-3-Phosphate –Triacylglycerol–FAT

Question 3

Aldolase

Answer 3

splits F(1,6)BP into two molecules: G3P and DHAP

DHAP immediately isomerizes into G3P
