Pent-Phos Pathway Flashcards
1
Q
What types of enzymes are involved in the reversible reactions of the PPP
A
Transketolases and Transaldolases
2
Q
What are the substrates the at the PPP can use to generate Ribose-5-phosphate without generating NADPH
A
Fructose-6-phosphate, and Glyceraldehyde-3-phosphate.
3
Q
What is the first reaction of the oxidative pathway of the PPP?
A
Glucose-6-phosphate –> 6-phosphoglucolactone.
This is the primarily regulated reaction.
Catalyzed by: Glucose-6-phosphate Dehydrogenase
Controlled by levels of NADP/NADPH
