Cellular Respiration and Fermentation

Which equation best represents aerobic respiration?

• C6H12O6 + 6CO2 + ATP → 6O2 + 6H2O

• C6H12O6 + 6CO2 → 6O2 + 6H2O + ATP

• C6O2 + 6H2O → C6H12O6 + 6O2 + ATP

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Bacteria that need oxygen to grow are...

• Aerobic

• Anaerobic

• Facultative anaerobic

• Big

The three steps to aerobic cellular respiration are...

• Glycolysis, citric acid cycle, electron transport chain

• Glycolysis, lactic acid fermentation, electron transport chain

• Alcohol fermentation, photosynthesis, glycolysis

• None of the above

The starting carbohydrate that is broken down by glycolysis is...

• Glucose

• Lactose

• Pyruvic acid

• Citric acid

The products of alcohol fermentation include...

• Lactic acid and ethanol

• Carbon dioxide and water

• Lactic acid and carbon dioxide

• Ethanol and carbon dioxide

What is the disadvantage of bacteria fermenting instead of undergoing aerobic respiration?

• It produces 2 ATP instead of 38 ATP

• For some microbes, it produces a waste that is 12% toxic

• Both of these are disadvantages

• Neither of these are disadvantages

Most of the ATPs in a cell are produced by...

• The breakdown of glucose into pyruvic acid

• Electrons that are passed through the electron transport chain

• The breakdown of oxygen in aerobic conditions

• The breakdown of pyruvic acid to acetyl CoA

Yeast produces...

• Lactic acid and CO2

• Ethyl alcohol and CO2

• Acetic acid and H2

• Citric acid and O2

Lactic acid production indicates that this has occurred...

• Glycolysis

• Fermentation

• Kreb cycle

• Any of these

If oxygen is present, which group of reactions will occur?

• Glycolysis, citric acid cycle, electron transport chain

• Glycolysis, conversion of pyruvic acid to lactic acid

• Citric acid cycle, conversion of pyruvic acid to ethyl alcohol

• Only electron transport chain
