QUESTIONS AND CORRECT DETAILED
ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+
How much ATP is produced in each stage
of metabolism? - --ANSWER->>>>Glycolysis
- 2 ATP
PDH - NONE
TCA - 2 GTP (2 ATP)
OxPhos - 5 from malate-aspartate
- 5 from NADH from pyruvate
- 3 from FADH2
- 15 from TCA
,What 3 reasons are there for needing
glycogen? - --ANSWER->>>>1) breaks down
quickly for Fight or Flight
2) glucose released from breakdown
generates energy
3) brain needs glucose. glycogen in liver
provides glucose during fasting
Where is glycogen stored? - --ANSWER-
>>>>muscle and liver
how many glucose in glycogen? - --
ANSWER->>>>12-14
How often are alpha 1-6 bonds? - --
ANSWER->>>>every 5-6 glucose residues
,Which end is reducing and which is non-
reducing? - --ANSWER->>>>1 is reducing, 4
is non-reducing
what does curvature mean for properties of
glycogen? - --ANSWER->>>>compact
packing
Steps of Glycogen synthesis - --ANSWER-
>>>>1) G converted to G-6-P (hexokinase
IV) then G-1-P (phosphoglucomutase)
2) Combines with UTP to make UDP-
glucose + pyrophosphate (UDP-glucose
Pyrophosphorylase)
3) Glycogenin have Tyr that attacks UDP-
glucose using glycotransferase activity
, 4) More glucose can be added using chain-
extending activity by Glycogen synthase
5) Once 11 glucose are in a chain, Glycogen
branching enzyme transfers 7 residues and
makes alpha 1-6 bonds
What is the effect of glycogen branching? - -
-ANSWER->>>>increased solubility
Steps of glycogen breakdown - --ANSWER-
>>>>1) glycogen phosphorylase does:
orthophosphate + glycogen -> G-1-P +
glycogen (n-1)
2) Debranching enzyme shifts 3 residues to
another branch, then cleaves alpha-1,6
bond to release one glucose
3) Phosphoglucomutase does:
