Chapter 7 Biology Pe

Cellular Respiration

QuestionAnswer
Alcoholic fermentation Yeast uses this process to convert pyruvic acid to ethyl and carbon dioxide
Pyruvic acid Three-carbon product of gycolysis
Acetyl CoA Two-carbon; Pyruvic acid reacts with coenzyme A
Aerobic respiration Process that produces large amounts of ATP
Anaerobic respiration Does not require oxygen
NADH Reduced electron carrier molecule formed in glycolysis
Oxaloacetic acid Four-carbon molecule that combines with acetyl CoA
Citric acid Six-carbon molecule in the Krebs cycle
NAD+ Electron carrier molecule that is oxidized when G3P
Cellular respiration The process in which cells make ATP by breaking down organic compounds
Mitochondrial matrix The space inside the inner membrane of a mitochondrion
FAD (flavin adenine dinucleotide) Electron carrier molecule similiar to NAD+
Glycolysis Pathway in which two molecules of pyruvic acid are produced
Krebs cycle Pathway that breaks down acetyl CoA, producing CO2, hydrogen atoms, and ATP
Fermentation The recycling of NAD+ under anaerobic conditions
Kilocalorie Unit of energy = 1000 calories
Lactic acid fermentation An enzyme converts pyruvic acid into 3-carbon compound called lactic acid
Cristae Folds in the inner membrane of the mitochondrion
Electron transport chain A series of moleculesin a membrane that transfers electrons from one molecule to another
Redox reaction One reactant is oxidized (loses electrons) while another is reduced (gains electrons)
Cellular respiration steps Glycolysis and Aerobic respiration

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.
