Answer:
A
Explanation:
An organic matter would be something made from a living organism and has carbon in it- if you look the only answer that would properly fit these criteria would be A: Sugar because it can be made from plants and it does include carbon.
Answer:
Pyruvate helps in the production of ATP.
Explanation:
The molecule of pyruvate converted into acetyl CoA. Then each molecule which is produced during glycolysis loses electron and carbondioxide releases. After the breakdown of pyruvate, the electrons loses by pyruvate are transferred to NAD+ in order to produce NADH, which will be used by the cell to produce energy molecule such as ATP. So we can say that pyruvate plays a vital role in the formation of ATP molecule.
It is quite possible to combine the same two elements to form two different compounds. An example would be carbon dioxide CO2 and carbon monoxide CO. Thus, two elements can form different types of bonds and end up with completely different compounds. Like, Hydrocarbons are compounds made of Hydrogen and Carbon only, and there are many different hydrocarbons. There is a limited number of elements, but a larger number of compounds because of the example demonstrated above.
