What is the difference between glycogen breakdown in liver and in muscle?
- Release vs. consumption
The difference in glycogen breakdown in liver vs muscle is mainly due to their different metabolic needs. The liver supplies other organs with glucose and therefore needs to export the glucose released ...
Glucose, Glycogen, Glycolysis and Krebs Cycle
See attached file.
Answer 1, 2 and 6
1. Both glycogen and cellulose are polyglucose molecules.
a. Draw the basic structure of each (two glucose units in the main chain and one in the branch is sufficient), numbering all atoms
b. Compare and contrast the function of these related compounds
c. What is/are the molecular reasons for this functional difference?
d. How do you suppose a cell can make these two separate molecules without making errors such as glycogen-cellulose hybrid molecules?
2. Diagram the pathway of Glycolysis from glucose to pyruvate, giving structures and names of all pathway intermediates (enzyme mechanisms are not required) and names of enzymes (no abbreviations). Indicate where ADP, ATP, Pi, NAD+, or NADH is a substrate or product of a reaction.
6. Diagram the Krebs Citric Acid Cycle, beginning with pyruvate, giving structures and names of all enzyme substrates and products and names of enzymes (no abbreviations). Include on your diagram where (see attached file) where coenzyme A, H2O, or CO2 are substrates or products of reactions.View Full Posting Details
