Biology CP

Chapter 7

QuestionAnswer
Aerobic respiration process that produces large amounts of ATP
2 stages of Aerobic respiration Krebs cycle and Electron Transport Chain
Krebs Cycle First stage of Aerobic Respiration; It is a biochemical pathway that breaks down acetyl CoA
Products of Krebs cycle co2, H atoms, and ATP
How many ATP molecules are made in CR? maximum ATP made=38
Glycolysis pathway in which two molecules of pyruvic acid are produced
When cells break down food molecules, energy is temporarily stored in ATP molecules
ATP is essential for a cell to perform all the tasks necessary for life
a substance produced during photosynthesis that is used for completion of cellular respiration is oxygen
when glycolysis occurs, a molecule of glucose is split, two molecules of pyruvic acid are made, and some ATP is produced
the name of the process that takes place when organic compounds are broken down in the absence of oxygen fermentation
When muscles are exercised extensively in the absence of sufficient oxygen, lactic acid is produced
pyruvic acid three-carbon product of glycolysis
NADH is a/an an electron carrier
Anaerobic means without oxygen
alcoholic fermentation... makes ethyl alcohol
kilocalorie unit of energy
cytosol location of glycolysis
NAD+ electron acceptor
cell membrane location of electron transport chain in prokaryotes
yeast cells produce alcohol and carbon dioxide in the process of alcoholic fermentation
in cellular respiration, glycolysis immediately precedes the krebs cycle
in CR, more energy is transferred in.. the electron transport chain, than in any other step
The breakdown of organic compounds to produce ATP is known as cellular respiration
An important molecule generated by both lactic acid fermentation and alcoholic fermentation is NAD+
The energy efficiency of CR is approximately 39 percent
The krebs cycle occurs in the Matrix
mitochondrial matrix the space inside the inner membrane of a mitochondrion
citric acid six-carbon molecule in the Krebs cycle
NAD+ electron carrier molecule that is oxidized when G3P is reduced
FAD electron carrier molecule similar to NAD+
oxaloacetic acid four-carbon molecule that combines with acetyl CoA

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.
