PS II is an old system
Another ETC?
What an RPP-off
100

Organisms like us, which must consume high-energy molecules from other organisms in order to keep living.

What are heterotrophs?

100

This term refers to the idea of light as a particle -- a particle of electromagnetic radiation.

What is a photon?

100

These are the two major parts of a photosystem.

What are the light-havesting complex and the reaction center?

100

This is the photosystem that we consider to be first in the light reactions.

What is photosystem II?

100

These are the three major steps of the Calvin Cycle.

What are carbon fixation, reduction, and regeneration (of the starting material)?

200

This term refers to the set of cells (tissue) within the middle of a leaf, the cells of the leaf that do most of the photosynthesis.

What is mesophyll?

200
This term refers to the distance traveled by light, as it goes through one complete cycle of electromagnetic oscillation.

What is wavelength?

200

This is a photosynthetic pigment that is useful for gathering energy for photosynthesis, but also for protecting chlorophyll by absorbing photons that have so much energy that they would damage it.

What are carotenes? or

What is beta-carotene?

200

This component of the light reactions moves H+ across the thylakoid membrane.

What is the cytochrome complex?

200

This is the five-carbon molecule that is one of the starting materials of the Calvin cycle.

What is RuBP? or 

What is ribulose bisphosphate?

300

This term refers to the openings, primarily found in the bottom side of a leaf, where O2 and water exit to the atmosphere and CO2 comes in from the outside.

What are stomata?

300

A photon with a short wavelength would be also said to have this, which refers to how fast it is going through its electromagnetic oscillations.

What is a high frequency?

300

This is the place within a photosystem where a special pair of chlorophyll molecules exist.

What is the reaction center?

300

This is the location where H+ are moved to, as electrons are passed along the light reactions' ETC.

What is the thylakoid lumen?

300
This is the molecule that is made as a product of the carbon fixation step.

What is 3PG? or

What is 3-phosphoglycerate?

400

This term refers to the space inside the chloroplast where the Calvin cycle takes place.

What is the stroma?
400

These are two types of electromagnetic radiation that have less energy per photon than visible light photons do.

What are (any two of): radiowaves, microwaves, infrared, or possibly other answers?

400

This is what the special pair of chlorophyll a molecules do, after they receive energy.

What is to pass electrons to a primary electron acceptor?

400

This is the molecule that accepts electrons from PS I, and which can do a couple of different things with those electrons.

What is Fd? or

What is ferredoxin?

400

These are the total numbers of NADPH and ATP, respectively, used in the Calvin Cycle for every three carbon fixations.

What are 6 NADPH and 9 ATP?

500

This is the name of the other type of autotrophs, such as the bacteria that get their energy by oxidizing Fe(II) into Fe(III) at iron mountain mine.

What are chemo-autotrophs?

500

These are two types of electromagnetic radiation that have longer wavelengths than visible light.

What are (any two of): radiowaves, microwaves, infrared, or possibly other answers?

Ha ha!

500

This is where photosystem II gets its electrons to replace those that it lost.

What is water? or

What is the water-splitting reaction?

500

This is the final destination for all electrons that start out in the light reactions.

What is NADPH?

500

This is the fraction of all the glyceraldehyde-3-phosphate formed in the Calvin Cycle that can actually be used to make glucose.

What is 1/6?
