Answer 2

What do u think it should be ?

Answer 3

Well, if in cellular respiration: Oxygen and Glucose, or C6H12O6, are broken down and used to produce ATP, adenosine triphosphate, CO2, and water.

Answer 4

Then the answer should be.......?

Answer 6

Glycolysis -> Kreb's Cycle -> Electron Transport Chain -> Chemiosmosis

Glycolysis: Glucose + 2 ATP -> 2 Pyruvate + 4 ATP+2 NADH
Glucose is ingested by the organism and brought into the cell through active transport. The Glucose molecule is phosphorylated, that is a phospate group is attached to both ends, and pulled apart. The phosphate group is then detatched from the split glucose and attached to ADP by an enzyme, forming ATP and Pyruvate.


Kreb's Cycle: 2 Pyruvate+ 2 H2O -> 8 NADH + 2 FADH2 + 2 ATP + 4 CO2
Pyruvate is oxydized to form Acytl-CoA which is inserted into the Kreb's Cycle. This action produces 2 NADH molecules. When in the Kreb's Cycle, the Acytl-CoA is changed, removing 2 Carbon atoms in the form of CO2, and generating 1 ATP for each pyruvate that entered the cycle. Hydrogen atoms are removed during this cycle and attached to the electron carriers NAD and FAD for use in the Electron transport Chain.

Electron Tranasport Chain and Chemiosmosis: 10 NADH + 2 FADH2 + 3 O2 -> 34 ATP + 6 H2O
NADH and FADH2 are put through a series of enzymes where the Hydrogen atoms are removed to form an Electron Gradient. This gradient drives movement through a proton 'pump' that produces energy from the flow of the atoms. Each NADH that enters the ETC will produce 3 ATP molecules. Each FADH2 will produce 2 ATP.

@Abhisar thats a much better face than that other creepy one (sorry, but the other one scares me)
