Does wood have moving molecules? Yes it does - molecules move in all substances. The motion depends on the nature of the substance (solid, liquid or gas) at a particular temperature and pressure. Wood is solid and the molecules are strongly cross-linked to each other so at room temperature and normal pressure, they do not move very much.

When wood burns, oxygen and sugar molecules disappear, and they are replaced by carbon dioxide and water molecules. Molecules are not conserved in chemical reactions. However, the same atoms that make up the reactant molecules form the product molecules. Thus, atoms are rearranged in different molecules.

It is apparent, however, that one Oxygen molecule is not sufficient to burn one Methane molecule. Methane contains 5 atoms (1 C and 4 H). The C atom needs 2 O atoms to form one CO 2 molecule. A couple of H atoms needs one O atom to form one H 2 O molecule, and there are two such couples. Summing up, the methane molecule requires 4 O atoms, that are found in 2 oxygen O 2 molecules.

Seeds, roots, stems (wood and bark of woody plants): storage of calories and N 3. Enzymes catalysts: speed up chemical reactions but are not consumed or changed by the reaction As enzymes, proteins are responsible for all metabolic reactions and the synthesis of all of the other molecules found in organisms (pigments, hormones, etc.)
