U4CWPQ2 - Partner Quiz 2: Energy Pathways Video

What is the role of mitochondria in respiration?

• To transport oxygen from the lungs
• To metabolize simple sugars into ATP.
• To absorb blue and red light from the sun
• To break down carbohydrates

Which of the following is NOT a product of respiration?

• Water
• Carbohydrates
• Oxygen
• Carbon dioxide

Why do plants release more oxygen during photosynthesis than they use during respiration?

• Because oxygen is a product of photosynthesis and a reactant (input) in cell respiration
• Because they need more carbon dioxide for photosynthesis
• Because they require oxygen to run cellular respiration
• Because they need more water for photosynthesis

What is the main difference between chlorophyll and enzymes?

• Chlorophyll absorbs light, while enzymes use light
• Chlorophyll is a pigment, while enzymes are catalysts
• Chlorophyll is found in plants, while enzymes are found only in animals
• Chlorophyll is used in respiration, while enzymes are used in photosynthesis

Where is the energy used in photosynthesis originally found?

• The Sun
• Simple sugars
• Enzymes
• Oxygen

What is the main similarity between photosynthesis and respiration?

• Both reactions use enzymes
• Both reactions produce oxygen
• Both reactions occur in plants and animals
• Both reactions require energy

What is the process of breaking down carbon dioxide and releasing oxygen called?

• Photosynthesis
• Respiration
• Combustion
• Synthesis

Which is NOT a difference between photosynthesis and respiration?

• Photosynthesis produces carbohydrates, while respiration breaks them down
• Photosynthesis requires sunlight, while respiration does not
• Photosynthesis occurs in ONLY plants, while respiration occurs in ONLY animals
• Photosynthesis releases oxygen, while respiration uses oxygen

What is the main purpose of photosynthesis?

• To break down carbohydrates
• To produce energy for living processes
• To release oxygen into the environment
• To capture solar energy in the bonds of glucose and other carbohydrates

What is the main purpose of cellular respiration?

• To break down carbohydrates
• To produce energy for living processes in the form of ATP
• To capture carbon for plant growth
• To release oxygen into the environment
