Total questions: 10
Worksheet time: 3mins
What is the process whereby light energy is captured by plant, algal, or bacterial cells and is used to synthesize organic molecules from CO2 and H2O (or H2S)?
Protein Synthesis
Hydrolysis
Photosynthesis
Chemical Synthesis
It is the first of two stages in the process of photosynthesis. During the light reactions, photosystem II and photosystem I absorb light energy and produce ATP, NADPH, and O2
Light Dependent Reaction
Light Independent Reaction
Cellular Respiration
Glycolysis
It is an energy intermediate that provides the energy and electrons to drive the Calvin cycle during photosynthesis
NADP+
ATP
NADPH
NAPDH
A distinct complex of proteins and pigment molecules in chloroplasts that generates oxygen from water during the light reactions of photosynthesis
Carotenoid
Photosystem II
Photosystem I
Chlorophyll c
The combined action of photosystem II and photosystem I in which electrons flow in a linear manner to produce
Cyclic electron flow
Noncyclic electron flow
Cyclic proton flow
Noncyclic proton flow
The molecule in which a high-energy electron from an excited pigment molecule such as P680* is transferred during photosynthesis
Cytochrome Complex
Primary electron acceptor
Plastoquinone
Plastocyanin
NADPH2 and ATP produced by the light-dependent reactions are used to reduce what?
Carbon Dioxide
Carbon Monoxide
Oxygen
Hydrogen
Where is the site of the light-dependent reactions?
Stroma
Thylakoid membranes
Chlorophyll
Chemiosmosis
It is the movement of ions across a semipermeable membrane-bound structure, down their electrochemical gradient. An example of this would be the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis
Chemiosmosis
ETC
Diffusion
None of the above
Which of the following is NOT a product of Light Dependent Reaction?
ATP
Glucose
O2
NADPH
