Ch 7 quiz
1. The light reactions occur in the ________, while the Calvin cycle occurs in the
________. (1 point)
A) stroma . . . thylakoid membranes
B) stroma . . . nucleus
C) cytoplasm . . . stroma
D) cytoplasm . . . thylakoid membrane
E) thylakoid membranes . . . stroma
2. How are thylakoids and granum related?
Granum are stacks of thykaloids
3. CO2 enters and O2 escapes from a leaf via
A) stomata.
B) thylakoids.
C) grana.
D) stroma.
E) central vacuoles.
4. What does a photon of light do in a light reaction?
Excites chlorophyll and energizes an electron
5. What are the input and outputs of the Calvin cycle?
Input- CO2, ATP, NADPG. Output- G3P
6. What is a CAM plant?
A plant that divides photosynthesis between day and night. During the night a CAM plant
forma a 4-C compound that fixes CO2 for storage and use in the calvin cycle during the
day. Stomata are only opened at night
7. The electron transport chains of the light reactions
A) are located in the stroma.
B) are very different from those of cellular respiration.
C) shuttle electrons along in a series of redox reactions.
D) provide energy for the Krebs cycle.
E) are found on the inner membrane of chloroplasts.
8. Outline the Calvin Cycle. Include the inputs, Carbon Fixation, Number of
ATP/NADPH used, and outputs
3 CO2 are fixed to RuBP using Rubisco. Forms 6 3-PGA. Addition of 6 ATP and 6
NADPH for form 6 G3P. 1 G3P is used to make glucose. 5 G3P are converted back into 3
RUBP for use again
