Fermentation

Fermentation involves

• aerobic respiration
• anaerobic respiration 

Yeast is a(n)

• autotroph
• producer
• heterotroph
• plant

Why is yeast used to bake bread? 

• The waste gas, CO_2, makes bread rise
• The alcohol produced makes bread dangerous
• The yeast consumes O₂, causing bread to rise

What is a disadvantage of fermentation as a process? 

• It produces too much ATP
• It only produces 2 ATP
• It occurs in the absence of oxygen
• It is only for quick bursts of energy

What cells in the body may undergo lactic acid fermentation during exercise? 

• Muscle cells
• Fat cells
• Liver cells
• Skin cells

Lactic acid fermentation occurs in your muscles after a workout because your cells are struggling to get

• Glucose
• Sunlight
• Oxygen
• Water

Fermentation is cellular respiration without which molecule?

• CO₂
• O₂
• C₆H₁₂O₆

The process carried out by yeast that causes bread to rise is

• alcoholic fermentation
• lactic acid fermentation
• cellular respiration
• yeast mitosis

After intense activity, your muscles feel sore because of 

• the accumulation of NAD+
• the accumulation of lactic acid 
• the accumulation of ATP
• the accumulation of carbon dioxide

Which of the following is NOT made by fermentation

• Sauerkraut
• Bread
• Olive oil
• Yogurt
