Glycolysis - Biochemistry

Front

What is glycolysis?

Back

Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process.

Front

What is the net ATP yield from glycolysis?

Back

The net yield from glycolysis is 2 ATP per glucose molecule.

Front

What is the role of Hexokinase in glycolysis?

Back

Hexokinase catalyzes the conversion of glucose to glucose-6-phosphate, the first step in glycolysis.

Front

What is the function of NAD⁺ in glycolysis?

Back

NAD⁺ acts as an electron carrier, accepting electrons during the oxidation of glyceraldehyde-3-phosphate.

Front

What is the significance of Fructose-1,6-BisPhosphate in glycolysis?

Back

Fructose-1,6-BisPhosphate is a key intermediate that is split into two three-carbon molecules, DHAP and G3P.

Front

What is the difference between DHAP and G3P?

Back

DHAP (Dihydroxyacetone phosphate) is an isomer of G3P (Glyceraldehyde-3-phosphate) and can be converted into G3P.

Front

What is the role of Phosphofructokinase (PFK) in glycolysis?

Back

PFK is a key regulatory enzyme that catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate.

Front

What are the end products of glycolysis?

Back

The end products of glycolysis are 2 pyruvate molecules, 2 ATP, and 2 NADH.

Front

Is oxygen required for glycolysis?

Back

No, glycolysis does not require oxygen; it is an anaerobic process.

Front

What is the role of ATP in glycolysis?

Back

ATP is used as an energy source to phosphorylate glucose and intermediates, facilitating the glycolytic pathway.
