Respiration

QuestionAnswer
Location of glycolysis cytoplasm
State what happens during glycolysis glucose is converted into an intermediate which is converted into pyruvate
State what is meant by energy investment 2 ATP required to phosphorylate glucose
State what is meant by energy payout 2 ATP in but 4 ATP out OR net gain of 2 ATP
Does glycolysis require oxygen no
Does NAD go to NADH during respiration yes
Are dehydrogenases found in glycolysis yes
Define dehydrogenase removes H ions and electrons and pass to NAD to form NADH
Define NAD accepts H ions and electron to go from NAD to NADH Takes H ions and electrons to go to the electron transport chain
Location of citric acid cycle matrix of mitochondria
State what happens to pyruvate in aerobic conditions forms acetyl
Describe the citric acid cycle acetyl joins with oxaloacetate to form citrate and through a series of enzyme controlled steps oxaloacetate is regenerated
Are dehydrogenases found in citric acid cycle yes
Is pyruvate to acetyl part of the citric acid cycle no
Which substance is released when pyruvate goes to acetyl carbon dioxide
Which 3 substances are released by the citric acid cycle CO2, ATP and NADH
Which stage of respiration occurs in the cristae of the mitochondria Electron transport chain
Are dehydrogenases found in the electron transport chain No
State the first step of the electron transport chain NADH goes back to NAD releasing H ions and electrons
Which substance passes along the proteins in the cristae electrons
Hydrogens are pumped across the cristate by active transport. Which substance provides the energy for this. electrons
Explain how ATP is produced in the electron transport chain The return flow/diffusion of H ions across ATP synthase causes ADP + Pi to make ATP
The final hydrogen and electron acceptor is oxygen
Name the products of the electron transport chain ATP, water and NAD
Is carbon dioxide found in the electron transport chain No

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.
