QuestionAnswer
Light Reactions Absolutely needs light, in the thylakoid of the chloroplast, coverts solar energy to short-term chemical energy (happen first)
Dark Reactions/Calvin Cycle May or may not use light, in the Stroma of the Chloroplast, mainly responsible for Carbon Fixation (happens second)
Carbon Fixation Performs reduction reactions (adding electrons) to CO2
Pigment Material that changes the color of reflected/transmitted light as a result of wavelength absorption
Chlorophyll Green pigment in algae, cyanobacteria, and plants essential for photosynthesis. It is part of the reaction center for PSI and absorbs certain wavelengths of light (esp. blue and red)
Accessory Pigment Helper pigments, not necessary, but helpful, use up quite a few wavelengths
Action Spectrum Graph rate of photosynthesis at various wavelengths
Antennae Complex/Light-Harvesting Complex Pigments are arranged in a complex, array of hundred of different pigment molecules
Reaction Center 2 Special Chlorophyll A molecules
Plastoquinone- A quinone (type of organic compound) mobile electron carrier in photsynthesis A quinone (type of organic compound) mobile electron carrier in photsynthesis
Plastocyanin Mobile electron carrier in photosynthesis, a protein containing Copper
Ferredoxins Iron-sulfer proteins that mediate electron transfer
Oxidative Phosphorylation Pathway that uses Proton gradient as energy source
Carboxylase Enzyme in Dark Reactions that adds CO2
Oxygenase Enzyme in Dark Reactions that can react with oxygen

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
