Glycolysis and Krebs Cycle

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvic acid, producing a small amount of ATP and NADH in the process.

Front

What is the end product of glycolysis?

Back

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

Front

Does glycolysis require oxygen?

Back

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

Front

What is the net gain of ATP molecules from glycolysis?

Back

The net gain of ATP molecules from glycolysis is 2.

Front

What is the Krebs cycle also known as?

Back

The Krebs cycle is also known as the citric acid cycle or the tricarboxylic acid (TCA) cycle.

Front

What are the main inputs of the Krebs cycle?

Back

The main inputs of the Krebs cycle are acetyl-CoA, NAD+, FAD, and water.

Front

What are the main outputs of the Krebs cycle?

Back

The main outputs of the Krebs cycle are CO2, ATP, NADH, and FADH2.

Front

How many NADH molecules are produced from one turn of the Krebs cycle?

Back

One turn of the Krebs cycle produces 3 NADH molecules.

Front

What is the role of NADH in cellular respiration?

Back

NADH serves as an electron carrier, transporting electrons to the electron transport chain for ATP production.

Front

What is the significance of acetyl-CoA in metabolism?

Back

Acetyl-CoA is a key molecule that enters the Krebs cycle and is derived from carbohydrates, fats, and proteins.
