Cellular Respiration

QuestionAnswer
cellular respiration is the complex process i nwhich cells make adenosine triphosphate (ATP) by breaking down organic compounds
pyruvic acid a three-carbon compound that is produced duting glycolysis and needed for both the aerobic and anaerobic pathways of cellular respiration that follow glycolysis
NAD+ an organic molecule that serves as an electron carrier by being oxidized to NAD+ and reduced to NADH
anaerobic glyoclysis is this process because it does not require the presence of oxygen
aerobic respiration if oxygen is present in the cell's environment, pyruvic acid is broken down and NADH is used to make a large amount of ATP through a process known as ________
glycolysis is a biochemical pathway in which one six-carbon molecule of glucose is oxidized to produce two three-carbon mosecules of pyruvic acid. It is a series of chemical reactions catalyzed by specific enzymes. All of the reactions of this take place in cytosol
NAD+ an organic molecule that accepts electrons during redox reactions
fermination the combination of glycolysis and these additional pathways, which regenerate NAD+.
latic acid fermentation an enzyme converts pyruvic acid made during glycolysis into another three-carbon compound, called lactic acid.
alcoholic fermentation some plant cells and unicellular organisms,such as yeast, use this process to convert pyrucic acid ito ethyl alcohol.
kilocalories a unit of energy equal to 1,000 cal
mitochondrial matrix mitochondrion. contains the enzymes needed to catalyze the reactions of the Krebs cycle
acetyl CoA a compound that is synthesized by cells and that plays a mojor role in metabolism
Krebs cycle is a biochemical pathway that breaks down acetyl CoA, producig Co2 hydrogen atoms, and ATP.
oxaloacetic acid
citric acid a sis-carbon compound formed in the Krebs cycle
FAD a compound that acts as a hydrogen acceptor in dehydrogenation reactions

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.
