Glycolysis

Front

What is glycolysis?

Back

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

Front

How many ATP molecules are required to start glycolysis?

Back

Two ATP molecules are required to initiate glycolysis.

Front

What is the end product of glycolysis?

Back

The end product of glycolysis is pyruvic acid (pyruvate).

Front

Does glycolysis require oxygen?

Back

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

Front

What is the role of NAD+ in glycolysis?

Back

NAD+ acts as an electron carrier, accepting high-energy electrons to form NADH.

Front

How many high-energy electrons are passed to NAD+ to produce NADH in glycolysis?

Back

Four high-energy electrons are passed to NAD+ to produce NADH.

Front

What is the net gain of ATP from glycolysis?

Back

The net gain of ATP from glycolysis is two ATP molecules.

Front

What type of reaction occurs during glycolysis?

Back

Glycolysis involves a series of enzymatic reactions that break down glucose.

Front

What is the significance of glycolysis in cellular respiration?

Back

Glycolysis is the first step in cellular respiration, providing energy and substrates for further metabolic processes.

Front

What happens to pyruvate after glycolysis in the presence of oxygen?

Back

In the presence of oxygen, pyruvate is converted into acetyl-CoA and enters the Krebs cycle.
