Cellular Respiration

Use this to learn the steps of Cellular Respiration in the correct order

Step 1 of Glycolysis 2 ATP's are spent splitting a 6 carbon glucose to form two, 3-carbon G3P molecules
Step 2 of Glycolysis the G3P's are rearranged to form two 3-carbon pyruvate molecules. 4 ATP's and 2 NADH molecules are produced.
Step 1 of the Krebs Cycle Acetyl Co-A is added to a 4 carbon molecule (oxaloacetate) to make a 6 carbon molecule (citrate)
Step 2 of the Krebs Cycle 1 carbon is removed to form CO2 and produces 1 NADH (5 carbons left)
Step 3 of the Krebs Cycle Another carbon is removed and forms CO2. This prodcues 1 NADH and 1 ATP molecule (4 carbons left)
Step 4 of the Krebs Cycle 1 FADH2 and 1 NADH are produced turning the molecule back into 4 carbon oxaloacetate
Step 1 of the Electron Transport Chain NADH and FADH2 drop off their electrons at the electron transport chain
Step 2 of the Electron Transport Chain As electrons pass down the chain hydrogen is pumped into the inter membrane space creating a concentration gradient
Step 3 of the Electron Transport Chain Oxygen acts as a final electron receptor and bonds with 2 hydrogen ions to form water (waste product)
Step 4 of the Electron Transport Chain Hydrogen passes back into the matrix via ATP synthase. The energy produced by this passing allows ATP synthase to make 34 ATP molecules.
Transition step before the Krebs Cycle Pyruvate is changed into Acetyl Co-A by removing 1 carbon. This produces 1 NADH and 1 CO2.
Step 5 of the Krebs Cycle Oxaloacetate is added to another Acetyl Co-A and the krebs cycle turns a second time.

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.
