BMSC 230- Module 2: Glycolysis-
practice Test Questions Well Answered
2026 Updated.
glycolysis is found in - Answer nearly all prokaryotic and eukaryotic cells
in eukaryotes, where does glycolysis occur - Answer cytosol
as soon as glucose is transported into the cell, the enzymes of glycolysis can immediately act on
it
glycolysis converts one molecule of glucose to - Answer two molecules of pyruvate
what are the two major functions of glycolysis - Answer 1. generate ATP
2. a number of the intermediates of this pathway serve as building blocks for the biosynthesis of
other biomolecules (amino acids and fatty acids)
why is glycolysis a central pathway - Answer involved in metabolizing glucose, which is a fuel
used by almost all organisms
glucose is a __ carbon molecule - Answer 6
glucose is converted into - Answer two 3-carbon molecules of pyruvate
during the conversion of glucose to pyruvate how many ATP are consumed - Answer 2 ATP
consumed in the first stage
in the second stage of glycolysis, how many ATP are produced - Answer 4 ATP produced per
molecule of glucose
glycolysis produces a net of __ ATP per molecule of glucose - Answer 2
where does most of the glucose come from that enters glycolysis - Answer - most dietary
carbohydrates are in the form of starch which is a polymer of glucose units linked together
-digestion of lactose
, -degradation of sucrose
-breakdown of maltose
glucose doesn't just diffuse across the cell membrane to get into the cell; rather: - Answer
there are specific transporters that assist
-several types of glucose transporters that have different functions and are present in different
tissues-
what is the first step of glycolysis - Answer phosphorylation of glucose
explain phosphorylation of glucose - Answer when glucose enters the cell, it is rapidly
phosphorylated by hexokinase to form glucose-6-phosphate
why is the first step of glycolysis so important - Answer since phosphorylation of glucose traps
it in the cell and prevents it from being transported out
what are kinases - Answer enzymes that phosphorylate biomolecules using ATP as the
phosphate donor
are kinases reversible? - Answer no
is the first step of glycolysis reversible? - Answer no - irreversible
what is the second step of glycolysis - Answer glucose-6-phosphate to fructose-6-phosphate
the conversion of glucose-6-P to fructose-6-P is what kind of reaction - Answer isomerization
what is an isomerization reaction - Answer no atoms lost, but only a rearrangement of the
atoms occurs
-reversible reactions-
what is involved in the isomerization reaction in the second step of glycolysis - Answer the
conversion of an aldose to a ketose by phosphoglucose isomerase.
