The fluid-filled interior compartment of the thylakoid network is referred to as the:
In plants and algae, _____ is the source of the electrons needed for photosynthesis.
In plants and algae, which of the following is a by-product of photosynthesis?
Which of the following is TRUE concerning the Calvin cycle and light-harvesting reactions of photosynthesis?
they take place in different compartments of the same organelle
Which of the following does NOT happen in the Calvin cycle of photosynthesis?
reduction of NADP+ to NADPH
Which of the following CORRECTLY describes the role of rubisco in the Calvin cycle?
Rubisco incorporates CO2 from the atmosphere into an organic molecule
Which step of the Calvin cycle would be affected first by a lack of NADPH?
In photosynthesis, the reduction of 3-phosphoglycerate to form carbohydrate requires:
ATP and NADPH
Carbon enters the Calvin cycle in the form of:
Where are the chlorophyll molecules located in plant cells that carry out photosynthesis?
in the thylakoid membranes
In a thylakoid membrane, absorbed light energy is passed from one chlorophyll molecule to another until it is:
passed to the reaction center
As electrons flow from one photosystem to another, the amount of energy present in the electrons decreases. How does the plant cell use the energy lost by the electrons?
The energy is used to create and maintain a proton gradient.
Chloroplast ATP synthases are powered by the flow of protons from the:
thylakoid lumen to the stroma
In the light-dependent reactions of photosynthesis, light energy is captured and stored as potential energy. In which of the following is this energy stored in the light-dependent reactions?
NADPH, ATP, and an electrochemical gradient
