Cell Energy Quizs

What is fermentation?

• An aerobic process that converts glucose to energy with oxygen.

• A process that occurs only in plants to produce oxygen.

• An anaerobic process that converts glucose to energy without oxygen.

• A method of preserving food using high temperatures.

Where does cellular respiration take place?

• In the mitochondria of eukaryotic cells.

• In the chloroplasts of plant cells.

• In the nucleus of prokaryotic cells.

• In the cytoplasm of all cells.

What is the equation for cellular respiration?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + energy.

• C6H12O6 + 3O2 → 3CO2 + 3H2O + energy.

• C6H12O6 + 6O2 → 3CO2 + 3H2O + energy.

• C6H12O6 + 6O2 → 6CO + 6H2O + energy.

What is the role of chlorophyll in photosynthesis?

• It captures sunlight energy.

• It absorbs carbon dioxide from the air.

• It releases oxygen into the atmosphere.

• It converts glucose into starch.

What is the purpose of cellular respiration?

• To convert glucose to usable energy.

• To produce oxygen for photosynthesis.

• To store energy in the form of starch.

• To break down proteins into amino acids.

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration requires oxygen; anaerobic does not.

• Aerobic respiration occurs in the absence of oxygen; anaerobic requires oxygen.

• Aerobic respiration is faster than anaerobic respiration.

• Aerobic respiration produces less energy than anaerobic respiration.

Do plants complete cellular respiration?

• Yes, they need to complete cellular respiration to transform the chemical energy stored in the bonds of glucose to ATP, the energy currency of the cell.

• No, plants only perform photosynthesis and do not require cellular respiration.

• Yes, but only during the night when photosynthesis is not occurring.

• No, plants do not require any form of respiration.

How do plants obtain the carbon dioxide needed for photosynthesis?

• Through small openings in their leaves called stomata.

• By absorbing it through their roots.

• From the air through their flowers.

• By converting sunlight into carbon dioxide.

What is the role of the mitochondria?

• It is the powerhouse of the cell where cellular respiration occurs.

• It is responsible for protein synthesis.

• It stores genetic information.

• It regulates the cell's water balance.

What is the relationship between photosynthesis and cellular respiration?

• The products of one reaction are the reactants of the other.

• Both processes occur in the mitochondria.

• Photosynthesis occurs only at night, while cellular respiration occurs during the day.

• Photosynthesis produces carbon dioxide, while cellular respiration produces oxygen.
