What is the goal of Glycolysis? correct answers To turn Glucose into pryuvate, so it can enter
into the Krebs cycle to produce more energy and generate ATP (Energy) in the process.
What is the first step in the Glycolysis process? correct answers Glucose---->Glucose 6
Phosphate
(addition of a phosphate)
What is the mechanism by which the first step in glycolysis occurs? What is expended in the
process? correct answers phosphorylation: ATP
What enzyme phosphorylizes Glucose into Glucose 6 Phosphate in step 1? correct answers
hexokinase
What are the steps in Glycolysis in which ATP is used? correct answers Steps 1: Glucose -----
> Glucose 6 phosphate
Step 3: Fructose 6 phosphate ----> Fructose 1,6 phosphate
What are the steps in Glycolysis in which ATP is gained? correct answers Steps 7 and 10
How many reactions are there total in Glycolysis? correct answers 10
What is Step 2 in the Glycolysis process? correct answers Glucose 6 phosphate -----> fructose
6 phosphate
What enzyme facilitates the change from Glucose 6 phosphate to fructose 6 phosphate in Step
2 of glycolysis? correct answers Phosoglucose Isomerase
What are the 3 major types of enzymes involved in Glycolysis? correct answers Kinases,
Isomerases, and Aldolases.
What does a Kinase do? correct answers phosphorylation/ dephosphorylation
(addition and subtraction of a phosphate)
What does an Isomerase do? correct answers Changes shape, not composition
What does an Aldolase do? correct answers Cleaves sugar into smaller sugars.
What is the third step in the Glycolysis process? correct answers fructose 6 phosphate----
>fructose 1,6 phosphate
What enzyme adds a phosphate to fructose 6 phosphate to make fructose 1,6, phosphate in
Step 3 of Glycolysis? correct answers phosphofructokinase
HINT:(phosphate + adding to fructose +kinase(a phosporylizer)
What is needed by phosofructokinase to produce fructose 1,6 phosphate from fructose 6
phosphate? correct answers An ATP molecule (2nd used in Glycolysis)
