Question 1

The two steps in photosynthesis are the light-dependent reactions and the Calvin cycle.
Which of the following is true regarding these two steps?
a
The light-dependent reactions use ATP from the Calvin cycle, and the Calvin cycle uses energy from absorbed sunlight.
b
The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma.
c
During the light-dependent reactions, carbon dioxide is fixed to produce sugars that form glucose.
d
The Calvin cycle converts water molecules into oxygen gas as a byproduct of its reactions.
Question 2
A cell in the leaf of a green plant performs both photosynthesis and cellular respiration, often at the same time. Which statement best describes how these processes are related to each other?

a
Thermal energy from one process is used as the primary energy source for the other process.
b
Both processes require energy directly from the Sun.
c
Products of one process are used as some of the reactants for the other process.
d
Both processes produce carbon dioxide.
Question 3
Which molecule, synthesized by plants and other photoautotrophs, is a major source of energy for cellular processes in both plants and animals?

a
Chlorophyll
b
Glucose
c
Wax
d
Nucleic acid
Question 4
What happens when ATP is converted to ADP?

a
Energy is stored in bonds.
b
Energy remains in the same.
c
