Total questions: 15
Worksheet time: 15mins
The Calvin Cycle occurs in the
Thylakoid
Grana
Inner membrane of chloroplast
Stroma
5 carbon sugar that combines with CO2 in the Calvin Cycle
3-PGA
G3P
RuBP
Glucose
Which of the following is true of the Calvin Cycle?
carbon dioxide and energy (ATP and NADPH) are used to make organic compounds
energy is absorbed from sunlight and converted to chemical energy stored in ATP and NADPH
Occurs in the thylakoid
Occurs in the cytoplasm
Increasing carbon dioxide can increase photosynthesis, but only to a maximum rate because
There are not enough RuBP molecules
Oxygen cannot leave fast enough
Large amounts of CO2 cannot fit in the chloroplast
Calvin cycle can only go as fast as the light reactions
In the Calvin Cycle, ________ and ________ from the light dependent reactions convert PGA into G3P
O2, ATP
CO2, H2
ADP, NADPH
NADPH, ATP

3
6
1
12
The 5-Carbon molecules that the Calvin Cycle starts and ends with, is called _____________.

G3P
RuBP
RuDp
After 12 G3P molecules are created, 10 are used to regenerate _________, while the other 2 are used to create __________.
RuBP, C6H12O6
Glucose, CO2
ATP, Glucose
Glucose, RUBP
The CO2 used in the Calvin Cycle originates from ___________.
The light phase
The breakdown of the remaining G3P's
Diffusion through the stoma
Lumen of the Thylakoid
True or False: The Calvin Cycle returns ADP and NADP to the light dependent phase.
True
False
The enzyme responsible for Carbon Fixation in C3 Photosynthesis is
RuBisCo
PEP Carboxylase
Hexokinase
Pyruvate DeHydrogenase
The first molecule formed after CO2 is added to the Calvin Cycle is:
RuBP

Which molecule is regenerated at the end of the Calvin Cycle to accept new carbon dioxide molecules?
ATP
NADPH
RuBP
G3P
During the Calvin Cycle, ATP and NADPH are used to convert 3-PGA into which molecule?
