Cellular Respiration & Photosynthesis Review (Sp25)

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O
• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

What process is found in both aerobic and anaerobic metabolism?

• the Kreb's cycle

• oxidative phosphorylation

• the citric acid cycle

• glycolysis

Organisms make energy readily available by transferring the chemical bond energy of organic molecules to which of the following substances?

• ADP

• light energy

• ATP

• mineral salts

What statement BEST compares the biochemical processes of photosynthesis and cellular respiration?

• Photosynthesis is the bacterial process of creating energy while cellular respiration is the eukaryotic process of releasing energy.

• Photosynthesis is the process of trapping the energy of the Sun and storing it in glucose. Cellular respiration is the process of releasing the energy stored in the chemical bonds of glucose.

• Photosynthesis is the plant process of releasing and utilizing energy while cellular respiration is the animal process of releasing and utilizing energy.

• Photosynthesis is the process of trapping the energy of glucose. Cellular respiration is the process of releasing the energy stored in the bonds of the cell.

The table shows the direction and function of substances in a chemical reaction that takes place in the chloroplasts of plant cells. The table is missing a title and information at W, X, and Y. What is the direction, X, and function, Y, for the sugar molecules?

• . Direction X is out; function Y is to provide chemical energy for the plant cell.

• Direction X is in; function Y is to provide heat energy for the plant cell.

• Direction X is out; function Y is to form more chlorophyll for the plant cell.

• Direction X is in; function Y is to form large sugar molecules for the plant cell.

Which statement BEST describes anaerobic respiration?

• It requires oxygen and can produce lactic acid and alcohol.

• It does not require oxygen and produces oxygen and glucose as forms of stored energy.

• It produces fewer ATP molecules per reaction than aerobic respiration and generates less energy

• It produces more ATP molecules per reaction than aerobic respiration and generates more energy

A student designs a set-up to investigate germinating seeds. He lls a jar with seeds that have soaked in water. In the jar, he places a beaker that contains a solution of bromothymol blue. Bromothymol blue turns green in the presence of carbon dioxide. He will record his observations on Day 1, wait 24 hours, and record his observations again on Day 2. The experimental set-up is shown below

• Do germinating peas release carbon dioxide in the process of respiration?

• Do germinating peas release water in the process of photosynthesis?

• Do germinating peas release oxygen in the process of respiration?

• Do germinating peas absorb water in the process of photosynthesis?

Sugar is a complex molecule made of

• sodium, hydrogen, and nitrogen.

• carbon, hydrogen, and oxygen

• sodium and nitrogen, only.

• carbon and oxygen, only

Which question would help explain how photosynthesis and cellular respiration are connected?

• How does cellular respiration help animals?

• Does photosynthesis use glucose for energy?

• Are the products of cellular respiration used during photosynthesis?

• Do photosynthesis and cellular respiration convert the same materials?

When an individual exercises vigorously for more than 15 minutes, the muscle cells are unable to obtain oxygen from the blood quickly enough. As a result, the muscle cells

• stop functioning properly, resulting in cramps.

• pull oxygen through the skin in order to continue working.

• send signals to the brain telling it to shut the muscles down.

• start anaerobic respiration, producing lactic acid buildup.
