Most schools don't let you use wiki as a source. Just scroll down and use the sources at the bottom of the page...MunztaTronSir wrote: » -

i lol'd
i put wrong things about the subject we were doing in history class on wiki,
4 people had that info on their report. -
C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
There are 3 steps in this process.
The first step is glycolysis, this converts sugar to pyruvate, a 3 carbon compound. This process also occurs in other organisms that do not use oxygen. In the presence of O2, pyruvate is converted to acetyl CoA and enters the next process which is Citric acid cyce or Kreb's cycle. In the absent of O2, pyruvate enters the fermentation process.
The second step is Kreb's cycle, in this process, acetyl CoA is converted to many organic compounds to oxaloacetic acid, which is recyled and used again in converting pyruvate to acetyl CoA. During this process, lot of electron is released, and these electrons are transferred to many electron acceptors such as NADH or NADPH,FADH.
Electron acceptors enter then to the next process, Electon transport chain coupled by oxidative phosphorylation. This process is involved in the massive production of ATPs, and the final electron acceptor is oxygen.
In conclusion, cellular respiration converts chemical energy to electrical energy back to chemical energy (ATPs) that will fuel cellular activities, thus converting it to heat energy.
I have the calvin cycle,citric acid cycle, C4 plant cycle and the photosynthesis cycle If you need anymore help -

Instead of wasting your time trolling, be useful in society please. Or act normal unlike what you do IRL.#2 student in michigan my ass.
Anyhow, a link and a pic for you.

Don't mess, Zifan Zhang. lol. -
Good info. Helped a lot. I already know the Calvin/C4/Photo cycle.robotgopher wrote: »C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy

How much ATP is produced and used throughout each process? -
Good info. Helped a lot. I already know the Calvin/C4/Photo cycle.

Tomorrow I am going to investigate this, and hopefully I will be able to give you some helpful input. If not, I am sure gonna ROK you. So good night my friend, and sleep safe in the knowledge that you got "DUKE" on the case:) -

I'm just gonna read from my notes.
Glycolosis 4 produced but the cell uses 2 ATP molecules during the process the same with the krebs cycle.
Glycolosis
2 pyruvic acid are produced
-net gain of 2 ATP molecules
-NAD+ is reduced to NADH
-reaction:C6 H12 O6 + 2 ATP = 2 pyruvic acids + 4 ATP
Electron transport chain- uses the high-energy electrons from the Krebs cycle to convert ADP omto ATP
-takes place in the mitochondria
-H2O (water) formed
-32 ATP produced
Krebs-pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
-takes place in the mitochondria
- pyruvic acid is broken down in acetyl coenzyme A, which goes into the Krebs cycle
-carbon is removed to produce CO2
-NAD+ amd FAD accept hydrogen ions and electrons and are therefore reduced to NADH and FADH2
-2 ATP are produced
FERMENTATION- releases energy from food molecules by producing ATP in the absence of oxygen
ALCOHOLIC FERMENTATION- In yeast cells, pyruvic acid gets turned into ethyl alcohol and carbon dioxide (CO2)
36 ATP per molecule of glucose. -
