Glycolysis is the metabolic pathway that converts glucose into?
C. Both A and B
D. None of the above
Explanation: Glycolysis is the metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO−, and a hydrogen ion, H+
Glycolysis is a sequence of five enzyme-catalyzed reactions.
C. Can be true or false
D. Can not say
Explanation: Glycolysis is a sequence of ten enzyme-catalyzed reactions.
The most common type of glycolysis is the?
Explanation: The most common type of glycolysis is the Embden–Meyerhof–Parnas (EMP) pathway, which was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas.
The glycolysis pathway can be separated into ________ phases.
Explanation: The glycolysis pathway can be separated into two phases: The Preparatory (or Investment) Phase – wherein ATP is consumed and The Pay Off Phase – wherein ATP is produced.
The first step is phosphorylation of glucose by a family of enzymes called?
D. All of the above
Explanation: The first step is phosphorylation of glucose by a family of enzymes called hexokinases to form glucose 6-phosphate (G6P). This reaction consumes ATP, but it acts to keep the glucose concentration low, promoting continuous transport of glucose into the cell through the plasma membrane transporters.
Glycolysis is an oxygen-independent metabolic pathway.
C. Can be yes or no
D. Can not say
Explanation: Yes, Glycolysis is an oxygen-independent metabolic pathway
What is the general term used for the anaerobic degradation of glucose to obtain energy?
Explanation: Fermentation is the general term used for the degradation of glucose to obtain energy in the form of ATP.
Cleavage of Fructose 1, 6-biophosphate yields ___________
A. Two aldoses
B. Two ketoses
C. An aldose and a ketose
D. Only a ketose
Explanation: Fructose 1, 6-biophosphate is cleaved to yield glyceraldehyde 3-phosphate, an aldehyde and dihydroxyacetone phosphate, a ketose
The deficiency of which of the following enzyme leads to galactosemia?
B. Pyruvate kinase
Explanation: In galactokinase deficiency galactosemia, high galactose concentrations are found in blood and urine.
Which of the following enzyme is responsible for the conversion of glucose 1-phosphate to glucose 6-phosphate?
A. Glycogen phosphorylase
Explanation: Phosphoglucomutase converts the glucose 1-phosphate to glucose 6-phosphate, which can enter glycolysis.
