Glycolysis and Fermentation

Front

What is glycolysis?

Back

Glycolysis is the metabolic process that breaks down glucose into pyruvate, producing a small amount of ATP and NADH in the absence of oxygen.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen by converting glucose into lactic acid or ethanol and carbon dioxide.

Front

Define anaerobic process.

Back

An anaerobic process is a metabolic process that occurs without the presence of oxygen.

Front

What is the net gain of ATP during glycolysis?

Back

The net gain of ATP during glycolysis is 2 ATP molecules.

Front

What is the role of NADH in cellular respiration?

Back

NADH is an electron carrier that transports electrons to the electron transport chain, where it helps produce ATP.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the main products of glycolysis?

Back

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

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is produced during the Krebs cycle?

Back

The Krebs cycle produces carbon dioxide, ATP, NADH, and FADH2.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons from NADH and FADH2 to oxygen, producing ATP.
