ET 3.7 Stages of Cellular Respiration 12/4/24

Front

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration that breaks down glucose into two molecules of pyruvic acid, producing a net gain of 2 ATP.

Front

What are the main products of glycolysis?

Back

The main products of glycolysis are 2 pyruvic acids and 2 ATP (net).

Front

What are the inputs required for glycolysis?

Back

The inputs for glycolysis are 1 glucose molecule, 2 ATP, and 2 NAD⁺.

Front

What is the end product of glycolysis?

Back

The end product of glycolysis is pyruvic acid.

Front

Which stage of cellular respiration requires oxygen?

Back

The electron transport chain requires oxygen.

Front

What is the role of NAD⁺ in glycolysis?

Back

NAD⁺ acts as an electron carrier, accepting electrons during glycolysis to form NADH.

Front

How many ATP molecules are produced in glycolysis?

Back

Glycolysis produces a total of 4 ATP, but the net gain is 2 ATP after accounting for the 2 ATP used.

Front

What happens to pyruvic acid after glycolysis in the presence of oxygen?

Back

In the presence of oxygen, pyruvic acid is converted into acetyl-CoA and enters the citric acid cycle.

Front

What is the citric acid cycle also known as?

Back

The citric acid cycle is also known as the Krebs cycle.

Front

What are the main products of the citric acid cycle?

Back

The main products of the citric acid cycle are NADH, FADH₂, ATP, and carbon dioxide.
