Acetyl CoA
Acetyl-CoA
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
When there is less amount of oxygen in muscle cells the Pyruvate (6 carbon molecule) is converted into lactic acid i.e another 3 carbon molecule therefore sudden activities change Pyruvate (6 carbon molecule)to lactic acid causing cramps and strains
Glucose is broken down to pyruvate during oxidative phosphorylation.
After a physical change the molecule remain intact.After a chemical change the molecule is modified.
Chemical change: the structure of the molecule is modified. Physical change: the structure of the molecule is not modified.
the strarch molecule binds to an enzyme
Chemical change: the structure of the molecule is chenged. Physical change: the structure of the molecule is not changed.
because you dont change the molecule. H2O IS THE SAME MOLECULE as water, ice or steam
what is the difference between a physical change and a physical property
A physical change doesn't modify the chemical nature of the molecule.A chemical change transform the molecule A in another molecule B.
It splits into a two-carbon acetyl group, which is added to Coenzyme A to make Acetyl-CoA, and a CO2.
