Cellular_Respiration

Questions on the Ch.9 study guide; Biology- Prentice Hall

QuestionAnswer
When is energy released from ATP? When it has a phosphate group removed; during Cellular Respiration
Write the stages of cellular respiration in order. **THIS IS WHEN OXYGEN IS PRESENT!** Glycolysis, Krebs Cycle and Electron Transport Chain
How many ATP molecules will be produced from one molecule of glucose? 38 ATP molecules
Cellular respiration requires energy by breaking down what? Glucose
Where in the cell do each of the following take place? 1. Glycolysis 2. Krebs Cycle 3.Electron Transport Chain 1. Cytoplasm 2. Matrix of Mitochondria 3. Inner-membrane of Mitochondria
What is the net gain of ATP molecules from the process of glycolysis? Two ATP molecules
What is the purpose of NADH? Energy Transporter
What are the two types of fermentation? Alcoholic fermentation and latic acid fermentation
Where does latic acid fermentation take place? Cytoplasm
What is one cause of muscle soreness? Lactic acid fermentation
What process is used to convert milk into yogurt? Lactic acid fermentation
The conversion of pyruvic acid into lactic acid requires what? NADH
What is the difference between aerobic and anaerobic processes, mainly? Anaerobic processes do not require oxygen and aerobic processes do
What organism is NOT likely to carry out cellular respiration? Bacteria, (anaerobic bacterium)
What is the starting molecule for the Krebs cycle? Either/or answers! acetyl-CoA or pyruvic acid
What passes high-energy electrons into the electron transport chain? NADH and FADH2
Each pair of high-energy electrons that move down the electron transport chain provides enough energy to do what? Convert ADP molecules into ATP molecules
Why do you breathe heavy after running a race? Oxygen debt must be repaid
When the body needs to exercise for longer then 90 seconds, it generates ATP by carrying out? Lactic acid fermentation
How are cellular respiration and photosynthesis almost opposite processes? They have the same chemical equations and reactions but reversed; photosynthesis STORES energy and cellular respiration RELEASES it.
What are the products of glycolysis? Two molecules of pyruvic acid, a net gain of two ATP molecules and 2 molecules of NADH
What is generated during lactic acid fermentation? Lactate, ATP, and NAD+
Where do the electrons moving along the inner membrane come from? Proteins
Where do the electrons moving along the inner membrane end up? ATP Synthase

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.
