Question 1
In a Utah forest ecosystem, lodgepole pine trees photosynthesize to convert radiant solar energy into chemical energy. Which balanced chemical equation accurately represents the primary inputs and products of photosynthesis?
Correct Answer:
6 CO2 + 6 H2O + light energy -> C6H12O6 + 6 O2
Question 2
During the light-dependent reactions in a plant thylakoid membrane, water molecules are split (photolysis). What are the immediate products of this water-splitting event?
Correct Answer:
Oxygen gas, hydrogen ions (protons), and electrons
Question 3
The Calvin cycle takes place in the stroma of chloroplasts. Which enzyme catalyzes the initial carbon fixation step by combining CO2 with a 5-carbon sugar?
Correct Answer:
Ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO)
Question 4
A bioenergetics researcher measures gas exchange in plant tissue in the dark. Which process explains why the tissue consumes O2 and releases CO2?
Correct Answer:
Aerobic cellular respiration
Question 5
Glycolysis is the initial pathway of cellular respiration occurring in the cytoplasm. What is the net yield of ATP and electron carriers per molecule of glucose oxidized in glycolysis?
Correct Answer:
2 ATP and 2 NADH
