PPP Flashcards
1
Q
Oxidative
A
irreversible
G6P: G6PD: Ribulose5Phosphate
(-) NADPH
to make NADPH
2
Q
Nonoxidative
A
reversible
Riboluse5Phosphate: trasketolases, B1, transaldolases: ribose5phosphate
to make nucleotides
3
Q
Tissues for oxidative
A
adipose: FA synthesis
Gonads: steroid
liver: FA
RBC: gluathione reduction (reactive o2)
4
Q
need NADPH only
A
oxidative = NADPH
nonoxidative to restart cycle
5
Q
NADPH and ribose5P
A
oxidative
6
Q
ribose 5P only
A
nonoxidative (high NADPH would inhibit)
7
Q
NADPH and pyruvate
A
both
8
Q
G6PD deficieincy (x linked)
A
no NADPH
hemolytic anemia: damage membrane bc Heinz bodies and reactive O2
