Cellular respiration
Storyboard Text
- Ana
- The three stages are Glycolysis, Kreb's cycle, and ETC.
- Marie
- Isn't the Kreb's Cycle aerobic and does not require energy to occur and takes place in mitochondria?
- Pedro
- There is a lot to know about cellular respiration.
- It uses CO2 in ETC to produce ATP.
- Glody
- That sounds fun, what is there to know about cellular respiration?
- There is a lot to know about cellular respiration.
- First, what is cellular respiration?
- Cellular respiration is the process that releases energy from food in the presence of oxygen.
- Don't cellular respiration have three stages? The the three stages are Glycolysis,Krebs Cycle,and ETC?
- Correct and in fact Glycolysis occurs in the cytoplasm of the cell. It's also anaerobic and is a pyruvic acid.
- Isn't the Krebs cycle aerobic and requires oxygen to occur and takes place in the mitochondria?
- I'm going to join in and tell you about ETC. ETC occurs in the mitochondria and is aerobic. It also requires energy and produces water as a waste product and makes a lot of energy for the cell of ATP.
- Correct, The Krebs cycle also uses carbon dioxide as a waste product.
- Wow that's a lot. Thanks for the good facts about cellular respiration. Thanks Mike for the information about ETC too.
- Your welcome
- Together,glycolysis, the krebs cycle and ETC generate 36 molecules of ATP per molecule and glucose used. That's a lot of energy!
