Cellular Respiration

QuestionAnswer
What is the purpose of cellular respiration? to turn food into ATP energy for cells
What kind of organisms do cellular respiration? plants and animals
Where do animals get the raw materials to do cellular respiration? glucose: from the food they eat oxygen: from breathing the air (O2 produced by plants)
Where do plants get the raw materials to do cellular respiration? glucose: produced from photosynthesis oxygen: produced from photosynthesis
what are the 3 reactions of cellular respiration? 1. glycolysis 2. krebs cycle 3. electron transport chain
What happens in glycolysis? glucose is split into 2 molecules of pyruvic acid. This requires 2 ATP and converts NAD+ into NADH
Where does glycolysis happen? in the cytoplasm
What happens in Krebs Cycle? Pyruvic acid is transported into the mitochondria and broken down. This releases CO2 as a waste product and the electron carriers NADH and FADH2
Where does the Krebs Cycle happen? mitochondria
What happens in the Electron Transport Chain? Electron carriers are used to make ATP, H+ ions combine with O2 to make water. This is the main ATP production step
Where does electron transport chain occur? Mitochondria
How many overall USABLE ATP are made from one glucose molecule going through cellular respiration? 36 ATP: 2 net from glycolysis 2 from Krebs cycle 32 from Electron Transport Chain
If oxygen is not available, how can organisms make energy? lactic acid fermentation (animals) alcoholic fermentation (yeast and microorganisms)
How does exercise affect your rate of cellular respiration? it causes cellular respiration to increase (more CO2 output)
What is the chemical formula for cellular respiration? C6H12O6 + 6O2 ----> 6CO2 + 6H2O + ATP ENERGY
what is the difference between aerobic and anaerobic respiration? aerobic requires oxygen (Krebs cycle and ETC) anaerobic does not require oxygen (glycolysis and fermentation)
What is the difference between a Calorie and a calorie? a calorie is the energy needed to raise the temperature of 1g of water by 1 degree Celsius. A Calorie is 1000 calories. Calorie is reported on food labels
What is calorimetry? Burning a portion of food to calculate the amount of heat gained by a known amount of water in order to calculate the number of Calories in the food
What is fermentation? making energy from food when there is no oxygen available
Is fermentation aerobic or anaerobic? Anaerobic:does not require oxygen
What are the 2 different kinds of fermentation? alcoholic respiration: done by yeast and microorganisms lactic acid fermentation: done by animals

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.
