Cellular Respiration and Fermentation

What is the purpose of oxygen in cellular respiration?

• To break down glucose

• To produce ATP

• To act as an electron acceptor

• To convert NADH to NAD+

What is the role of ATP in cellular processes?

• To power many cellular processes

• To convert glucose into pyruvate

• To regenerate NAD+

• To produce carbon dioxide

What is the product of glycolysis?

• Carbon dioxide

• Ethanol

• Lactate

• Pyruvate

Which type of fermentation produces ethanol?

• Alcoholic fermentation

• Lactic acid fermentation

• Aerobic respiration

• Anaerobic respiration

What happens to NADH in fermentation?

• It is converted to NAD+

• It is converted to ATP

• It is converted to pyruvate

• It is converted to carbon dioxide

Which organisms can perform anaerobic respiration on a regular basis?

• Bacteria and archaea

• Plants and animals

• Yeast and fungi

• Muscle cells and nerve cells

What is the waste product of alcoholic fermentation?

• Carbon dioxide

• Lactate

• Pyruvate

• Ethanol

What is the purpose of fermentation?

• To produce ATP in the absence of oxygen

• To convert glucose into pyruvate

• To regenerate NADH

• To break down ethanol

What is the end product of lactic acid fermentation? Remember it makes your muscles sore!

• Carbon dioxide

• Ethanol

• Lactate

• Pyruvate

What is the main difference between aerobic cellular respiration and fermentation?

• The presence of oxygen

• The production of ATP

• The involvement of NADH

• The formation of carbon dioxide
