Unit #4 Review

Cellular Respiration can have two pathways: Anaerobic vs Aerobic. The presence or absence of which of the following will determine the path of respiration?

• Water

• Carbon

• Oxygen

• Glucose

Cellular Respiration does not capture all of the energy stored in food. Some of the energy that is not transferred to cells is used to -

• maintain the organism's body temperature

• convert small molecules into larger ones

• join hydrogen and oxygen to create water

• transport proteins to all parts of the body

What is the purpose of ATP in both cellular respiration and photosynthesis?

• To breakdown glucose to release energy

• To work as an enzyme

• To absorb electrons from water

• To transfer energy from one molecule to another

What occurs inside of a cell while it is performing the process of photosynthesis?

• Sugar is broken down to generate adenosine triphosphate (ATP) molecules that are used for energy

• The negative charge inside of the cell is used to increase the concentration chemicals inside of the cell

• Light reactive chemicals combine carbon dioxide (CO2) and water to form glucose molecules that are stored as food

• The cell membrane forms around air bubbles to create a vacuole that is used to separate the oxygen from the rest of the air

Which of the following statements describes a process that occurs during photosynthesis, but not during cellular respiration?

• ATP is produced that stores energy

• Chemical energy is converted to light energy

• Reactions occur in the mitochondria of the cell

• Light energy is converted to chemical energy

In light reaction of photosynthesis, the products include -

• light energy and carbon dioxide

• chemical energy and oxygen

• water and carbon dioxide

• oxygen and nitrogen

Anything ending with -ase is classified as what?

• Carbohydrate

• Enzyme

• Lipid

• Nucleic Acid

In general, the rate of photosynthesis will increase if which of the following factors are present?

• Decreased temperature

• Increased presence of enzymes

• Increased light intensity

• Decreased carbon dioxide concentration

Yeast are single-celled fungi that contain many mitochondria, but chloroplasts are absent. Which gas will the yeast produce?

• Carbon dioxide will be produced due to cellular respiration

• Carbon dioxide will be produced due to photosynthesis

• Oxygen will be produced due to cellular respiration

• Oxygen will be produced due to photosynthesis

What occurs inside of a cell while it is performing the process of respiration?
