Glycolysis Enzymes Quiz
Test your knowledge on the enzymes involved in the glycolysis process, a fundamental metabolic pathway that breaks down glucose into pyruvate to generate ATP. Explore the roles and functions of enzymes like hexokinase, phosphofructokinase-1, and pyruvate kinase in the different steps of glycolysis.

- Card 1HintThink of it as the first step in extracting energy from sugar.Memory TipGlycolysis: Glucose to pyruvate
- Card 2HintIt adds a phosphate group to glucose, making it more reactive.Memory TipHexokinase: Hexa means six, it adds a phosphate to glucose
- Card 3HintIt changes the structure of G6P to F6P.Memory TipIsomerize: Change the structure, not the formula
- Card 4HintIt's a crucial control point for glycolysis.Memory TipPFK-1: Phosphorylates fructose, key regulator
- Card 5HintIt splits a sugar molecule in two.Memory TipAldolase: Aldo means sugar, cleaves the sugar
- Card 6HintIt interconverts two three-carbon sugars.Memory TipTPI: Triose phosphate isomerase, interconverts trioses
- Card 7HintIt's involved in a redox reaction, transferring electrons.Memory TipGAPDH: Uses NAD+ and oxidizes G3P
- Card 8HintIt generates ATP by transferring a phosphate group.Memory TipPGK: Kinase transfers phosphate, makes ATP
- Card 9HintIt moves a phosphate group within a molecule.Memory TipPGM: Muta means change, moves phosphate within
- Card 10HintIt removes water from a molecule.Memory TipEnolase: Eno means remove, removes a water molecule
- Card 11HintIt generates ATP and produces pyruvate.Memory TipPK: The final step of glycolysis, produces pyruvate
