5.2.2 Kreb’s Cycle ONLY (respiration) Flashcards
1
Q
The Kreb’s Cycle is…
A
A circular process that creates rNAD, rFAD and ATP
2
Q
First stage?
A
Oxaloacetate uses acetyl coA (2C) (from link reaction) to convert to citrate (6C), losing coenzyme A
3
Q
Second stage? What’s made?
A
Citrate (6C) loses a CO^2 and is converted to ketoglutarate (5C), making 1 rNAD from NAD in the process
4
Q
Third stage?
A
Ketoglutarate (5C) loses a CO^2 and is converted to oxaloacetate (4C)
5
Q
What’s made in the third stage? (In order)
A
rNAD, rFAD, rNAD, ATP
6
Q
Yield for one cycle?
A
3 rNAD, 1 rFAD, 2 CO^2, 1 ATP, 1 coenzyme A
7
Q
Yield for 1 glucose (2 cycles)?
A
5 rNAD, 2 rFAD, 4 CO^2, 2 ATP, 2 coenzyme A
8
Q
A
