BIOCVOC9

Biology I Chapter 9 vocab

TermDefinition
photosynthesis the process some organisms are able to use by which they convert light energy to chemical energy
Calvin cycle the main method photosynthesizing organisms use for carbon dioxide fixation
Krebs cycle a set of chemical reactions that break down pyruvate, producing electron carriers for an electron transport chain that powers ATP production
cellular respiration the process cells use to produce energy from carbohydrates
pigment a substance that absorbs some wavelengths of light and reflects others, giving something its color
chlorophyll the green substance that absorbs light and provides energy for photosynthesis
thylakoid disc-shaped sacs in chloroplasts in which photosynthesis takes place
electron transport chain the series of molecules in the inner membranes of chloroplasts and mitochondria down which excited electrons pass, releasing energy for ATP production
fermentation process by which NAD+ is recycled under anaerobic conditions in order to continue the break down of carbohydrates to supply energy for producing ATP
ATP adenosine triphosphate; a substance that stores and releases energy for most cell processes
aerobic describes a process that requires oxygen
anaerobic describes a process that does not require oxygen
glycolysis the process by which glucose is broken down into pyruvate in the absence of oxygen, producing a small amount of ATP
ATP synthase the enzyme that aids in the productions of adenosine triphosphate and which also acts as a carrier protein for hydrogen ions in active transport across a membrane

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.
