Chapter 4 Cells and Energy Photosynthesis and Cellular Resp

TermDefinition
ATP molecule that carries energy that cells can use, adenosine triphosphate, has 3 phosphate groups
ADP lower energy molecule, adenosine diphosphate, has 2 phosphate groups
chemosynthesis process by which some organisms us chemical energy to make food
photosynthesis process by which plants capture energy from sunlight and store it as chemical energy in the form of sugar
chlorophyll molecule in cholorplasts that absorbs sunlight and makes plants appear green
thylakoids shaped like coins, contain chlorophyll, where the light dependent reaction happens
light dependent reaction captures sunlight, breaks down water and releases oxygen
light independent reaction uses energy from light dependent and carbon dioxide to make sugar, happens in the stroma
stroma fluid outside the thylakoids where light indepedent reaction takes place
cellular respiration using oxygen to produce ATP by breaking down carbon based molecules, happens in the mitochondria
aerobic needs oxygen to happen
glycolysis breaks glucose into 2 molecules that each have 3 carbons
anaerobic means it does not need oxygen to happen
Krebs cycle produces a small amount of ATP and other molecules to the next part of cellular respiration, give off carbon dioxide as a waste product,happens in the matrix
electron transport chain energy is moved through a chain of proteins and a large number of ATP are produced, oxygen enters and is used to make water molecules as a waste produce, happens in inner membrane
fermentation does not make ATP, but allows glycolysis to continue, products are pyruvate, ATP and NADH
lactic acid no oxygen present after glycolysis happens, produced in your muscles
alcoholic fermentation happens in yeast and produces carbon dioxide, important in the baking industry

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.
