QuestionAnswer
What fact illustrates that the Krebs cycle is, in fact, a cycle? Oxaloacetate is the starting and ending compound of the cycle.
What is true regarding factors that affect the rate of cell respiration? IncreaseCO2ConcentrationDecreasesRateCellRespiration,ExtremeIncreaseTemperatureCanDecreaseRateOfCellRespirationDueToEnzymeDenaturation,DecreaseInGlucoseDecreasesRateOfCellRespiration,AnIncreaseInTemperatureIncreasesTheRateOfCellRespirationUpToAPoint
What are the products of the Krebs cycle? ATP, carbon dioxide, NADH, and FADH2
The Krebs cycle produces many electron carriers. What are these electron carriers? NADH and FADH2
Human cells can respire anaerobically. What is true regarding this process? Lactic acid is produced, only a small amount of ATP is produced, electrons are not transferred to the electron transport chain, and NADH does not enter the Krebs cycle
What happens during during the link reaction, the stage that links glycolysis to the Krebs cycle? acetyl-CoA is produced
During the_, hydrogen ions flow through_by_to make_by_phosphorylation._is the final electron acceptor and is used to produce water. ETC; ATP synthesis; facilitated diffusion; ATP; oxidative; oxygen
What happens as electrons move down the electron transport chain? Their energy is used to pump hydrogen ions across the mitochondrial inner membrane.
How do hydrogen ions flow through ATP synthase? They move from high to low concentration passively (facilitated diffusion).
The conversion of pyruvate to acetyl-CoA and the release of carbon dioxide is what type of reaction? Decarboxylation
What is a difference between aerobic respiration and anaerobic respiration in yeast? Anaerobic respiration produces ethanol, aerobic respiration does not.
Glucose has how much TOTAL number of products per glucose. 2 pyruvate, 2 net ATP, 2 NADH
Link Reaction has how much TOTAL number of products per glucose. 2 acetyl-CoA, 2 CO2
Krebs Cycle has how much TOTAL number of products per glucose. 6 NADH, 2 FADH2, 2 ATP, regeneration of oxaloacetate
By the time the Krebs cycle is complete, 6 carbon dioxide molecules have been released. Why does this make sense? Glucose has 6 carbons and has been completely broken down by this stage.
What happens during glycolysis, the first stage of respiration? A small amount of ATP is produced, NADH, an electron carrier is produced, Glucose is broken down gradually via several enzyme-controlled steps, and Glucose is split to form two molecules of pyruvate
What does a respirometer measure? The rate of cell respiration
The link between the electron transport chain and ATP synthesis... is a proton gradient
The Krebs cycle produces many electron carriers. Why are these important? They carry electrons to the electron transport chain.
Which of the following is a true statement comparing aerobic cell respiration to anaerobic cell respiration in some organisms? Carbon dioxide is a product of aerobic and anaerobic 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.
