Respiration lab

In the pea germination lab, which condition will show the highest rate of respiration?

• glass beads

• germinated peas

• non-germinated peas

• cooked peas

In the pea/cellular respiration lab, why won't the plant be undergoing photosynthesis?

• They were in the dark.

• They were just germinating and had no photosynthetic leaf tissues

• They were developed under artificial conditions

• They were mutant strains of peas.

In the pea germination lab, what is the purpose of KOH (potassium hydroxide)? 

• to absorb the oxygen, so you can measure CO2 production
• to absorb the CO2, so you can measure oxygen consumption

As oxygen is consumed, what will happen to the water in the pipet tubes?

• It stays in the same place.

• It moves out of the tube.

• It moves into the bottle.

• It moves into the tube.

In the pea germination experiment, what would you expect to happen to the rate of cellular respiration as the temperature cools down?

• It will be unchanged because the metabolic processes are independent of temperature. 
• It will speed up because enzymes work faster in cooler conditions. 
• It will slow down because enzymes slow down in cooler conditions. 
• It will speed up and then slow down as the enzymes run out of substrate. 

Where does aerobic respiration take place?

• Cytoplasm
• Mitochondria
• Stroma
• Thylakoid

Which type of respiration occurs in the presence of oxygen?

• Aerobic
• Anaerobic

What are the two reactants of cellular respiration?

• C₆H₁₂O₆ & 6CO₂
• 6 CO₂ & 6H₂O
• C₆H₁₂O₆ & 6O₂
• 6CO₂ & 6O₂

What are the two produces of aerobic respiration?

• Glucose & oxygen
• Carbon dioxide & water
• Lactic acid
• Carbon monoxide 

A process by which the cells of an organism release the energy stored in food.

• synthesis

• digestion

• cellular respiration

• hydrolysis
