Cellular Respiration

Everything you need to know about cellular respiration.

QuestionAnswer
How much ATP is produced in cellular respiration? 4
During what stage or process is ATP produced? Oxidative Phosphorylation
What are the reactants? Oxygen and glucose
What are the products? Carbon dioxide, water, and ATP
What is the chemical equation for cellular respiration? C6H12O2+6O2->6H2O+6CO2+ATP
Does cellular respiration require sunlight? No
What is the basic process of cellular respiration? The body intake of oxygen and glucose to produce carbon dioxide, water, and ATP.
What is the final electron acceptor in cellular respiration? Oxygen
What does the final electron accpetor determine in cellular respiration? Whether the respiration is aerobic or anaerobic.
What happens to carbon dioxide and water in cellular respiration? Nothing, they are the products.
What happens to glucose in cellular respiration? It is broken down into two pyruvates.
What happens to oxygen in cellular respiration? It becomes the final electron acceptor, and it determines whether it is aerobic or anaerobic respiration.
What are the stages in cellular respiration Glycolysis, Krebs Cycle(Citric Acid Cycle), and Oxidative Phosphorylation.
What happens during Glycolysis? Glucose is broken down into two molecules of pyruvate.
What must happen before Glycolysis can switch over to the Krebs Cycle? The oxidation of pyruvates.
What happens during the oxidation of pyruvates? Pyruvates are converted to acetyl Co enzyme A(acetyl CoA).
What carries out the step of oxidating the pyruvates? A multi-enzyme complex that catalyzes three reactions.
What happens during the Krebs Cycle? The break down of pyruvates to carbon dioxide is completed. Organic fuel of pyruvates is also oxidized, generating 1 ATP, 3 NADH, and 1 FADH2 per turn.
How many steps are in the Krebs Cycle? What is the catalyst for each step? There are eight steps, each catalyzed by a specific enzyme.
What happens during the steps of the Krebs Cycle? The first step has the group of acetyl from acetyl CoA combine with oxaloacetate to form citrate. The next seven steps decompose the citrate back to oxaloacetate.
What is produced from the Krebs Cycle? NADH and FADH2
What do the products of the Krebs Cycle do? Relay electrons extracted from food to the electron transport train.
What happens during Oxidative Phosphorylation? Chemiosmosis couples elctron transport to ATP synthesis.
Where does cellular respiration take place? In the mitochondria of animals and humans.
What powers ATP synthase? Hydrogen Ions(H+)
Where does ATP synthesis take place? In the Mitochondria.
What is the electron acceptor in cellular respiration? Oxygen
What is the source of power for the electron transport train(ETC)? Electron doners

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.
