Multiple Choice

What are the two main types of fermentation?

• NAD+ fermentation & ATP fermentation

• alcohol fermentation & lactic acid fermentation

• glucose fermentation & carbon dioxide fermentation

• ADP fermentation & ATP fermentation

Multiple Choice

Fermentation releases energy from food despite the lack of

• ATP

• carbon dioxide

• oxygen

• NADY

Multiple Choice

The process represented by the equation Pyruvic acid + NADH -> Alcohol + CO₂ + NAD⁺¹ is

• lactic acid fermentation

• glucose fermentation

• pyruvic acid fermentation

• alcoholic fermentation

Multiple Choice

Why is aerobic exercise an effective way to lose body fat?

• Aerobic exercise induces lactic acid fermentation, which reduces body fat

• aerobic exercise reduces the amount of glucose available for storage as body fat

• aerobic exercise burns stored fat for energy

• aerobic exercise starves muscles & causes oxygen debt

Multiple Choice

Runners breathe heavily after a race because their bodies need oxygen to

• help clear lactic acid from their systems

• get rid of pyruvic acid

• convert glucose to lactic acid

• perform fermentation
