• Model showing sugars, oxygen, ADP + P_i, mitochondria, carbon dioxide, water, X ATP

• Model showing sugars, oxygen, ADP + P_i, mitochondria, carbon dioxide, water, decreased ATP concentration

• Model showing sugars, oxygen, ADP + P_i, mitochondria, X carbon dioxide, water, increased ATP concentration

Why is Cellular Respiration so important to the body? (LS1.9 Cellular Respiration)

• It isn’t, Cellular Respiration only occurs in plants

• Cellular Respiration breaks down one molecule of glucose, in the presence of oxygen, to create 36 ATP. This is the best way our body receives energy.

• Cellular Respiration breaks Water and Carbon Dioxide to make Glucose.

• Cellular Respiration breaks down one molecule of glucose, in the absence of oxygen, to create 4 ATP

What can be concluded from the diagram? (LS1.8 Photosynthesis)

• Light energy is converted into chemical energy in photosynthesis.

• Light energy is converted into chemical energy in cellular respiration.

• Cellular respiration utilizes ATP to release energy in the form of heat.

• Photosynthesis releases oxygen and ATP that are used in cellular respiration.

The energy released from the anaerobic respiration of a glucose molecule is less than that released from the aerobic respiration of a glucose molecule because (LS1.9 Cellular Respiration)

• fewer bonds of the glucose molecule are broken in anaerobic respiratio than in aerobic respiration.

• more enzymes are required for anaerobic respiration than for aerobic respiration.

• anaerobic respiration occurs 24 hours a day, while aerobic respiration can only occur at night.

• anaerobic respiration requires oxygen but aerobic respiration does not require oxygen.

The cell membrane is described as highly selective, because it bars the passage of most but not all substances. What structural feature of the membrane acts like gates that allow certain substances, including water, to pass through the membrane?

• Permanent gaps in the lipid bilayer

• Proteins that temporarily dissolve regions of the lipid bilayer

• Channels in transmembrane proteins embedded in the lipid bilayer

• Channels in phosphate groups at the outer edges of the lipid bilayer

Which most accurately describes the differences in ATP production between aerobic respiration and anaerobic respiration?

• Aerobic respiration produces more ATP than anaerobic respiration.

• Anaerobic respiration produces more ATP than aerobic respiration.

• Only aerobic respiration produces measurable amounts of ATP.

• Anaerobic and aerobic respiration produce the same amount of ATP.

Estella spilled tomato sauce on her shirt. When she washed her shirt, she noticed that the detergent she used contained enzymes. Enzymes are added to detergents to break down proteins from food and other substances that may stain clothing. Which would MOST likely inhibit the ability of the enzymes to remove the stain on her shirt?

• the amount of dissolved minerals in the water

• the type of fibers from which her shirt was made

• the temperature of the water

• the fragrances in the detergent

Inhibitors prevent a substrate from interacting with the enzyme. How do inhibitors act upon an enzyme?

• Increase the rate of enzyme activity.

• Decrease the rate of enzyme activity.

• Increase enzyme activity rate initially, and then decrease the activity rate.

Which statement about photosynthesis is true?

• Photosynthesis occurs only during the day.

• Oxygen is consumed during the Calvin Cycle.

• Glucose is produced in the light-dependent reactions.

• The Calving Cycle does not require light.
