krebs cycle

QuestionAnswer
Where does the kreb cycle take place? Mitochondria!!!
What happens between glycolysis and the krebs cycle? 2 Pyruvates turn into 2 Acetyl Coa This results in NAD-> NADH and CO2 is released (oxidation)
Step 1 of kreb cycle Acetly Coa -> citrate Citrate synthesis
Step 2 of kreb cycle Citrate-> isocitrate ISOMERIZATION
Step 3 of kreb cycle Isocitrate->product - OXIDATION -REDUCTION OF NAD->NADH ***CO2 IS PRODUCED***
Step 4 of kreb cycle -OXIDATION -REDUCTION OF NAD->NADH ***CO2 IS PRODUCED***
Step 5 of kreb cycle -HYDROLYSIS -ADP+P -> ATP (Phosphorylation)
Step 6 of kreb cycle -HYDROGENATION -FAD->FADH2
Step 7 of kreb cycle HYDRATION :D
Step 8 of kreb cycle -OXIDATION -NAD->NADH (reduced)
In the electron transport chain, how many ATPs of NADH FADH2 are produced? NADH-> 2.5 ATP FADH-> 1.5 ATP 4 TOTAL!
Produced from the kreb cycle? 3 NADH-> 7.5 ATP 1 FADH2-> 1.5 ATP 1 ATP 10 ATPS TOTAL this turns twice for every glucose molecule, 20 ATP TOTAL!
In step 1, the molecule that enters the citric acid cycle is Acetyl CoA, which has two carbons. Glucose left glycolysis as pyruvate, which had three carbons. Where did the third carbon go? its a CO2 now...wow...im so happy for him...
How many CO2s total per glucose molecule, and per 2 turns? 4
How many ATP total per glucose molecule, and per 2 turns? 2
How many NADH total per glucose molecule, and per 2 turns? 6
How many FADH total per glucose molecule, and per 2 turns? 2
Is each of the following molecules produced from pyruvate under anaerobic or aerobic conditions? a. acetyl CoA b. lactate c. ethanol 1. Aerobic 2. Anaerobic 3. Anaerobic
In reaction 1, the Acetyl group from _____ combines with _____, forming _____ and _____ 1. Acetyl CoA 2. Oxaloacetate 3. Citrate 4. CoA
glucose → 2 pyruvate atp yield 7

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.
