Cellular respiration

QuestionAnswer
What is cellular respiration?
Write the equation for the formation of ATP.
What is ATP's role within cells?
Describe phosphorylation.
What is the substrate in the first stage of glycolysis?
Name the first phase of glycolysis.
Where does glycolysis take place in the cell?
Describe what happens in the first phase of glycolysis.
Name the second phase of glycolysis.
Describe what happens in the second stage of glycolysis.
Name the enzymes which remove hydrogen ions and electrons from compounds such as glucose.
State the name of the hydrogen acceptor that transports these hydrogen ions and electrons from glycolysis to another stage?
NAD binds with hydrogen ions and electrons to form which molecule?
Name the two phases that make up glycolysis.
What are the products of glycolysis?
What is the name of the second stage of aerobic respiration?
What happens to pyruvate at the start of the citric acid cycle?
During the citric acid cycle, name the molecule which acetyl coenzyme A combines with to form citrate.
Name the three products of the citric acid cycle.
What is the electron transport chain?
Where does the NADH used in the first part of stage 3 of respiration come from?
What does NADH provide stage 3 of respiration with?
During stage 3 of respiration, electrons are used to pump hydrogen ions across a membrane. This flow of ions helps to synthesise ATP. Name the enzyme which powers the reaction to make ATP.
Name the final hydrogen acceptor in respiration.
Name the substance produced in respiration when the final hydrogen acceptor combines with the hydrogen ions and electrons.
State the location of glycolysis.
State the location of the citric acid cycle.
State the location of the electron transport chain.
Name the phase during glycolysis where ATP is used up.
Name the phase during glycolysis where ATP is produced.
Apart from ATP name two other products of glycolysis.
Name the stages that are present in aerobic respiration but not fermentation.
Where does fermentation take place?
Describe fermentation in animals including the substrate(s), product(s) and whether it is a reversible or irreversible reaction.
Describe fermentation in plants and yeast including the substrate(s), product(s) and whether it is a reversible or irreversible reaction.
Describe the role of ATP in the first phase of glycolysis.
Explain how glycolysis results in a net gain of ATP.
Name the product(s) of fermentation in yeast.
Name the product(s) of fermentation in plants.
Name the product(s) of fermentation in animals.
Describe the role of ATP in the transfer of energy.
Describe the role of dehydrogenase enzymes in the conversion of intermediates to pyruvate.
State the conditions required for fermentation.

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.
