In an experiment, Stephanie placed a potted plant under a bell jar, completely sealing the jar to the table top. After placing a box over the bell jar for 24 hours, she measured the concentrations of oxygen and carbon dioxide in the gas in the jar. Which statement best describes the measurements she would find in the jar, compared with the concentrations of oxygen and carbon dioxide in the classroom air?

Back

Oxygen concentration increased; carbon dioxide concentration decreased.

Front

A diagram of cellular processes is provided. Which of the following lists of terms correctly identify the missing labels? Options: 1 = Chemical energy, 2 = Carbon dioxide, 3 = Respiration; 1 = Light energy, 2 = Carbon dioxide, 3 = Respiration; 1 = Light energy, 2 = Diatomic oxygen, 3 = Oxidation; 1 = Heat energy, 2 = Carbon dioxide, 3 = Respiration

Back

1 = Light energy, 2 = Carbon dioxide, 3 = Respiration

Front

A test tube is filled with water and a green plant called elodea. When the plant is exposed to sunlight, it begins to produce bubbles. What is the most likely identity of the gas in the bubbles?

Back

Carbon dioxide

Front

Which equation shows the process of photosynthesis?
Options:
C6H12O6 + 6H2O + light energy → 6CO2 + 6O2
C6H12O6 + 6O2 + light energy → 6H2O + 6CO2
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
6CO2 + 6O2 + light energy → 6H2O + C6H12O6

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Front

Which description in the table correctly identifies characteristics of aerobic and anaerobic respiration? Options: 1, 2, 3, 4

Back

1

Front

Why did Alexis Woods experience muscle pain after intense sprints?

Back

When the muscle cells do not receive enough oxygen to generate energy (ATP) through aerobic respiration, they undergo anaerobic respiration which results in the production of lactic acid. Lactic acid accumulates in the muscle cells and causes pain.

Front

Which of the following statements is true of the production of energy from matter?

• Photosynthesis creates energy from CO2 and H2O.
• Photosynthesis creates energy from carbohydrates.
• Cellular respiration creates energy from CO2 and H2O.
• Cellular respiration creates energy from carbohydrates.

Back

Cellular respiration creates energy from carbohydrates.

Front

Cellular respiration can be expressed by which of the following equations?
Options:
C6H12O6 + CO2 → 2 C2H5OH + 2 CO2
CH4 + 2 O2 → CO2 + 2 H2O + energy
6 H2O + 6 CO2 → C6H12O6 + 6 O2
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ~38 ATP

Back

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ~38 ATP

Front

What is the relationship between photosynthesis and cellular respiration?

Back

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