|
|
|
If oxygen is present, what stage follows glycolysis?
|
Krebs Cycle
|
|
|
Why is cellular respiration called aerobic respiration?
|
requires oxygen
|
|

|
|
|
What organisms can you find the electron transport chain in?
|
eukaryotes and prokaryotes
|
|
|
What are the electron carriers that power the elctron transport chain?
|
high energy electrons in NADH and FADH2 from the Krebs cycle
|
|
|
What is the energy of electrons in ETC used for?
|
Waste from cellular respiration such as low energy electrons and hydrogen ions.
|
|
|
Breathing heavy after running a race is your body's way of repaying what?
|
Replacing oxygen for energy to repay the ATP used
|
|
|
How does your body generate ATP after exercising for more than 10 minutes?
|
through celluar respiration
|
|
|
If you want to lose weight, how long should you exercise aerobically for each day?
|
more than 15-20 minutes (about 30) because your body stores enough glycogen for 14-20 minutes.
|
|
|
Energy to win a 2-minute foot race is produced by what process?
|
Muscle cells produce ATP by lactic acid fermentation
|
|
|
Why must well-conditioned athletes pace themselves?
|
Cellular respiration produces energy more slowly than fermentation, so athletes have to give their body time enough to produce it.
|
|
|
What are 3 sources of energy during exercise?
|
ATP in muscles
Carbohydrate glycogen Fats The last two are used in cellular respiration |
|
|
In eukaryotes, where is the elctron transport chain?
|
in the inner membrane of the mitochrondria
|
|
|
In the electron transport chain, each pair of high-energy electrons provides energy to produce what molecules?
|
water molecules
|
|
|
How are photosynthesis and cellular respiration almost opposite processes?
|
Photosynthesis makes energy and cellular respiration uses it.
Photosynthesis removes carbon dioxide from air and cellular respiration puts it back Photosynthesis releases oxygen and cellular respiration uses it to release energy from food |
|
|
What organelle does celluar respiration take place in?
|
Mitochrondria
|
|
|
What type of cells does celluar respiration take place in?
