Light Pig, Photosyn

Light and Pigment, Chemistry of Photosynthesis

QuestionAnswer
Travels as a wave but energy is carried in packets called: photons
We perceive different wavelengths of light as different colors
The colors we see are what is: reflected
primary photosynthetic pigment (blue-green) Chlorophyll a
yellow-green pigment Chlorophyll b
absorb energy and transfer to chlorophylls: accessory pigments
yellow accessory pigment Xanthophylls
orange accessory pigment Carotenes
red accessory pigments Phycobilins, Anthocyanins
Chloroplast structure includes a __________ __________ enclosed organelle double membrane
stacks of thylakoid membrane Grana
dense fluid surrounding grana Stroma
unit of several hundred chlorophyll molecules working together: Photosystem
A method of separating mixtures based on their solubility in a solvent system Chromotography
6CO₂ + 12 H₂O ----> C₆H₁₂O₆ + 6O₂ + 6 H₂O photosynthesis
Where do light-dependent reaction occur? in the thylakoid membrane stacks called grana
light-dependent reactions require: sunlight
light-dependent reactions consist of Photosystem I and II
During these reactions energy from sunlight is trapped and ATP and NADPH are produced. These products will be used in the: Calvin Cycle
Light-Independent Reactions are also known as Calvin Cycle or C₃ pathway
Where do Light-Independent Reactions occur? stroma
Light-Independent Reactions do NOT require: sunlight
ATP and NADPH from the light reactions are used to fix CO₂ into: glucose (C₆H₁₂O₆)
The Calvin Cycle begins and ends with the: 5-carbon sugar RUBP
What captures sunlight? chloroplasts
In photosynthesis, captured energy is transferred to the stable bonds of: glucose
during the process of photosynthesis, water is split to provide a source of electrons at which point ___________ is released oxygen
What is the ultimate food? glucose
6CO₂ + 12 H₂O ----> C₆H₁₂O₆ + 6O₂ + 6 H₂O ... what is the name of the first and second part of this equation? reactants, products

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.
