That depends on the molecules. They could collide giving a reaction, or nothing could happen.
A compound will form.
The smaller unit molecules which combine to form proteins and polypeptides are called amino acids. The amino acids are joined to each other by peptide bonds.
When atoms become bonded through covalent, ionic, or hydrogen bonds they form molecules.
Hydrogen and enzyme
Ions and molecules move into and out of the cell by two main methods:Passive transport does not require any energy. Molecules wither diffuse into the cell or enter the cell via transporter proteins located on the cell membrane.Active transport requires the use of ATP molecules to move ions or molecules into and out of the cell.
A combination of many disaccharides will yield a polysaccharaide, such as starch or cellulose
Chemical bonds are formed and energy is released.
molecules
The molecules of iron combine with molecules of oxygen to form molecules of iron oxide- or rust.
molecules
Burning is a chemical process by which two atoms or molecules will combine with each other. In burning, the two atoms or molecules will combine and release energy. Usually one of the two molecules is oxygen or something else chemically like it called an oxidizer. When the molecules combine and release energy, it is released in the form of heat and often light.
Not really. Molecules are combinations of atoms formed when they share electrons.
That happens all the time. Smaller molecules combine to form larger molecules; larger molecules break up into smaller molecules.
(Two or more than two ) Atoms or molecules of different elements combine to form compounds, like: Hydrogen(atom) and Chlorine combine to form HCL (an acid) Hydrogen(molecule) and oxygen combine to fom H2O (water)
They form an embryo
