Cellular Respiration Study Guide

QuestionAnswer
Write the equation for cellular respiration. C6H12O6 + 6O2 + Enzymes -> 6H20 + 6CO2 + Energy
What is the first stage of cellular respiration? Glycolysis
What is broken down in Glycolysis? Glucose
What is Glucose broken down into? 2 molecules of G3P
How many ATP’s are produced during the 1st stage of cell respiration?(net gain) 2 ATP
What is the name of the 2nd stage of cellular respiration if oxygen is present? Kreb's Cycle
What is used in the Kreb’s Cycle of cellular respiration from the 1st stage? Pyruvate
What is Pyruvate broken down into? Acetyl CoA
What is the name if the 2nd stage after Glycolysis if no oxygen is present? Fermentation
What is the total number of ATP’s produced in Fermentation? 2 ATP
How many carbon dioxide molecules are produced during the Kreb’s Cycle? 6 CO2
Explain the role of NAD+. To make electrons
How many ATP’s are produced during the ETC of cellular respiration? 34 or 32
What else is produced during the ETC? It is going to make more electrons
____Net ATP from Glycolysis ____ATP from the Kreb’s Cycle ____OR____ from the Electron Transport Chain (Using all the NADH or FADH2) ____=MAXIMUM number of ATP 2;2;34 OR 32;38
What makes oxidative respiration different from anaerobic respiration? 1 has oxygen and 1 does not
What is the function of Fermentation? produce ATP without O2
Name the two types of Fermentation. Lactic Acid and Alcoholic
Where and when does lactic acid occur? Cytoplasm in Mitochondria
What does lactic acid Fermentation produce? lactic acid
Is ATP produced during the lactic acid fermentation, if so, how many? yes and 2
Where does alcohol fermentation occur? Cytoplasm in Mitochondria
What does alcohol fermentation produce? Ethyal Alcohol
When organisms can perform both Aerobic and Anaerobic Respiration it is called? Facultative
What acts as an on/off switch for WHOLE process- in Glycolysis? Phosphofructokinase
It occurs in bacteria and Yeast (fungus) and Beer, wine, and bread is made from it. What is it? Alcoholic Fermentation

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.
