Quick 10Q: Glycolysis

Front

What is glycolysis?

Back

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

Front

What is the main function of glycolysis?

Back

To split the glucose molecule to release energy.

Front

What are the products of glycolysis?

Back

2 ATP, 2 NADH, and 2 pyruvate.

Front

Where does glycolysis take place?

Back

In the cytosol of the cell.

Front

Does glycolysis require oxygen?

Back

No, glycolysis does not require oxygen.

Front

What is the first step of glycolysis?

Back

The phosphorylation of glucose to glucose-6-phosphate.

Front

What enzyme catalyzes the first step of glycolysis?

Back

Hexokinase.

Front

What is the role of NAD+ in glycolysis?

Back

NAD+ acts as an electron carrier, being reduced to NADH during the process.

Front

What happens to pyruvate after glycolysis?

Back

Pyruvate can be converted into acetyl CoA for the Krebs cycle or fermented in anaerobic conditions.

Front

What is substrate-level phosphorylation?

Back

A process in glycolysis where ATP is produced directly from the transfer of a phosphate group to ADP.
