Patterns of Electron Flow through Light Reaction Events

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
