Glycolysis and Fermentation

Multiple Choice

What is the equation for photosynthesis?

• 6O2 + light energy -> 6CO2 + C6H12O6
• 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
• C6H12O6 + 6O2 -> 6CO2 + 6H2O
• 6CO2 + 6H2O -> C6H12O6 + 6O2

Multiple Choice

Where does cellular respiration take place?

• Mitochondria

• Endoplasmic reticulum
• Ribosomes
• Nucleus

Multiple Choice

How is chemosynthesis different than photosynthesis?

• Photosynthesis produces carbon dioxide, while chemosynthesis produces oxygen.
• Chemosynthesis occurs only in plants, while photosynthesis occurs in animals.
• Chemosynthesis uses chemical energy, while photosynthesis uses solar energy.
• Chemosynthesis is a process that requires sunlight, while photosynthesis does not.
