Question
Chapter 22, Problem 22.82GP
Interpretation Introduction
Interpretation:
The liver cell is to synthesise new glucose via gluconeogenesis and muscle cell use glucose via glycolysis, why this good physiological strategy for your body, the reason should be explained.
Concept Introduction:
Gluconeogenesis, it is the metabolic process by which glucose (or) glycogen is synthesized from non-carbohydrate precursors,
- Lactate is anaerobic
metabolism - Glycogenic amino acids, it is undergoes for protein degradation.
- Glycerol (Lipolysis)
- Propionyl-CoA
Glycolysis: This is one of biochemical pathway that breakdown a molecules of glucose into two molecules of pyruvate and producing for some energy.
Glycolysis occurs in the cytoplasm and has two major phases.
- Energy investment phase
- Energy payoff phase

which of the following is not true for a muscle that is forced to metabolize glucose anaerobically ?
- The cells breakdown glucose faster
- The cells produce less ATP per mole of glucose
- The cells metabolize glucose to lactate
- The activity of the cytosolic gycerol-3-phosphate dehydrogenase will be required for the muscle to sustain glycolysis
- The muscle quickly experiences fatigue if it is deficient in the enzyme lactate dehydrogenase
Which of the following statements about
glucose metabolism is correct? *
Red blood cells can catalyse aerobic
glycolysis because they contain oxygen
bound to haemoglobin.
Fructose cannot be used for
gluconeogenesis in the liver.
Glycolysis can proceed in the absence of
oxygen only if pyruvate is formed from
lactate in muscle.
All of the reactions of glycolysis are freely
reversible for gluconeogenesis.
Red blood cells can only metabolise
glucose by anaerobic glycolysis and the
pentose phosphate pathway.
Which enzyme deficiency is most likely to cause glycogen to be full of short, stubby branches compared to normally structure glycogen in the affected organ? Explain.
Muscle branching enzyme
Liver debranching enzyme
Muscle phosphorylase
Liver glycogen synthase
Glycogenin
