Chapter 9, AP Bio

Cellular Respiration and Fermentation

QuestionAnswer
What are examples of energy storing macromolecules? Carbohydrates, Lipids, and Proteins
What is fermentation? The partial break down of sugar when no oxygen is available.
What does cellular respiration release more of? Energy to make ATP.
Where does cellular respiration occur? In the cytoplasm and mitochondria.
What is the equation for cellular respiration? C6H12O6 + 6O2 -> 6CO2 + 6H2O + 36-38ATP
What is oxidation? The loss of electrons.
What is the equation for redox reactions and energy transfers? Na + Cl -> Na+ + Cl-
What is NAD+? Nicotinimide Adenine Dinucleotide. Common coenzyme oxidizing agent in cellular respiration.
Explain what happens when NADH transfers an electron. NADH will transfer an electron to an electron transport chain where energy will be released slowly to form ATP and at the end of the chain it will join 1/2 O2 and 2H+ to form water.
What are the 3 steps in cellular respiration? What is released here? Glycolysis in cytosol, citric acid cycle, and electron transport chain in mitochondria. CO2 is released.
What are the two different processes to make ATP? Oxidative phosphorylation and substrate level phosphorylation.
What is glycolysis? Splitting glucose.
What is made when glycolysis occurs? 2 pyruvates + 2H2O + 2ATP + 2NADH
What happens to NAD+ and glucose in glycolysis? NAD+ is reduced and glucose is oxidized.
In glycolysis, what is the overall energy gain? 2 ATP and 2 NADH

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.
