2.26 Glycolysis

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 main reactant that enters glycolysis?

Back

Glucose is the main reactant that enters glycolysis.

Front

What are the net products of glycolysis?

Back

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

Front

Where does NADH go after it is produced in glycolysis?

Back

NADH is transported to the Electron Transport Chain for further energy production.

Front

What happens to NAD+ during glycolysis?

Back

NAD+ accepts electrons and is reduced to NADH.

Front

How many ATP molecules are produced from one glucose molecule during glycolysis?

Back

A net gain of 2 ATP molecules is produced from one glucose molecule during glycolysis.

Front

What is the role of ATP in glycolysis?

Back

ATP provides the energy required to initiate the glycolysis process and is also produced as a product.

Front

What is the significance of pyruvate in glycolysis?

Back

Pyruvate is the end product of glycolysis and can be further processed in the Krebs Cycle or converted to lactate.

Front

What is the function of enzymes in glycolysis?

Back

Enzymes facilitate the chemical reactions in glycolysis, speeding up the conversion of glucose to pyruvate.

Front

What is substrate-level phosphorylation?

Back

Substrate-level phosphorylation is the direct synthesis of ATP from ADP and a phosphorylated intermediate during glycolysis.
