Detailed Study of Respiration

What is produced during glycolysis?

• ATP

• NADH

• Pyruvic acid

• All of the above

What happens to pyruvic acid if oxygen is present?

• It enters the mitochondrion

• It is converted to lactic acid

• It is broken down in the cytosol

• It is converted to ethanol

What is the main aim of the electron transport system?

• To produce ATP

• To produce NADH

• To release carbon dioxide

• To form water

What is oxidative phosphorylation?

• The production of ATP

• The breakdown of glucose

• The conversion of NADH to NAD+

• The formation of lactic acid

What is the result of anaerobic respiration?

• Production of ATP

• Production of ethanol

• Production of lactic acid

• Both B and C

What is the test for the presence of carbon dioxide?

• Limewater turns clear to milky

• Iodoform test

• Potassium dichromate test

• None of the above

What is the effect of cyanide on the electron transport system?

• It enhances ATP production

• It prevents ATP production

• It has no effect

• It increases oxygen consumption

What is the role of NADH in respiration?

• To carry electrons

• To produce ATP

• To release carbon dioxide

• To form glucose

What is produced when NADH breaks down?

• NAD+

• ATP

• Pyruvic acid

• Lactic acid

What is the temperature controlled at during the experiment?

• 30°C

• 25°C

• 35°C

• 40°C
