chlorophyll a Response Feedback: Electrons are funneled to a central chlorophyll a molecule, referred to as the reaction center. Question 6 0.5 out of 0.5 points The light-harvesting complexes of a chloroplast are located in the ______; the enzymes of the Calvin cycle reactions are located in the _________. Answer Selected Answer: thylakoid membrane; stroma Response Feedback: The photosystems are located in the thylakoid membrane; the Calvin cycle reactions occur within the semifluid stroma of the chloroplast. Question 7 0.5 out of 0.5 points Which of the following correctly describes CO 2 fixation in a C3 plant? Answer Selected Answer: Rubisco combines CO 2 with RuBP to form a 6-carbon compound that then breaks down into two 3-carbon compounds. Response Feedback: Carbon dioxide is continually fed into the process by rubisco at the beginning of the Calvin cycle reactions. Question 8 0 out of 0.5 points The light reactions produce __________, which are used in the Calvin cycle. The Calvin cycle produces __________, which are in turn used in the light reactions. Answer Selected Answer: ADP and NADH; ATP and NADPH Response Feedback: The products of the light reactions, ATP and NADPH, supply energy and reducing power to the Calvin cycle. The by-products of the Calvin cycle, ADP, inorganic P, and NADP, are returned to the light reactions.

Question 9 0.5 out of 0.5 points The enzyme-rich solution found within the chloroplast is called the ________. Answer Selected Answer: stroma Response Feedback: Among other things, the stroma contains enzymes that participate in the Calvin cycle reactions. Question 10 0.5 out of 0.5 points RuBP carboxylase (rubisco) is able to bind with both Answer Selected Answer: Carbon dioxide and oxygen. Response Feedback: Rubisco has an affinity for both oxygen and carbon dioxide. It is the affinity of rubisco that leads to the need for C4 and CAM photosynthesis.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
