Module 11 Set 4

QuestionAnswer
TCA cycle oxidation steps form NADH and FADH2
TCA cycle completes substrate-level phosphorylation
TCA cycle energy drives condensation of acetyl group with oxaloacetate
TCA cycle oxidation and decarboxylation steps form NADH + H+ and CO2
TCA cycle performs complete oxidation and degradation
TCA Cycle step 1: Cycle begins by adding C2 acetyl group to C4 molecule, forming citrate; also called the citric acid cycle.
TCA Cycle step 2: Acetyl group is then oxidized to two molecules of CO2.
TCA Cycle step 3: During the oxidation process, most electrons (e) are accepted by NAD+ and NADH is formed.
TCA Cycle step 4: In one instance, electrons are taken by FAD, which becomes FADH2.
TCA Cycle step 5: NADH and FADH2 carry these electrons to electron transport system.
TCA Cycle step 6: Some energy released is used to synthesize ATP by substrate-level phosphorylation
for each acetyl-CoA molecule oxidized, TCA cycle generates 2 molecules of CO2
for each acetyl-CoA molecule oxidized, TCA cycle generates 3 molecules of NADH
for each acetyl-CoA molecule oxidized, TCA cycle generates one FADH2 and GTP

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.
