Question

True or False

_ Under aerobic conditions in the human body, pyruvate is converted to ethanol.

_ In muscle, the product of glycogenolysis is glucose

_ Glucose-1-Phosphate occurs only in glycogenesis

_ Glucose-6-phosphase is involved in glycolysis, gluconeogenesis, glycogenolysis and glycogenesis.

_ Glucose-1-phosphate is the final product of glycogenolysis in the liver.

Answer 1

Under aerobic conditions in the human body, pyruvate is converted to ethanol: False

In muscle, the product of glycogenolysis is glucose: False. Muscle cells lack the enzyme glucose-6-phosphatase and thus cannot convert glucose-6-phosphate (which cannot be transported across the cell membrane) to glucose.

Glucose-1-Phosphate occurs only in glycogenesis: False

Glucose-6-phosphate is involved in glycolysis, gluconeogenesis, glycogenolysis and glycogenesis: True (I think, you indicated in your question Glucose-6-phosphate instead of Glucose-6-phosphase).

Glucose-1-phosphate is the final product of glycogenolysis in the liver: False
