That depends on the molecules. They could collide giving a reaction, or nothing could happen.
A combination of many disaccharides will yield a polysaccharaide, such as starch or cellulose
A diagram would show an enzyme (such as alpha-amylase) binding to maltose and two glucose molecules, facilitating the reaction to form maltose. The enzyme would assist in breaking down the bond between the two glucose molecules, allowing them to combine with the maltose molecule. The resulting product would be maltose formed from the combination of one maltose molecule and two glucose molecules.
The smaller unit molecules that combine to form proteins and polypeptides are called amino acids. Amino acids are linked together through peptide bonds to form chains that ultimately fold into functional protein structures.
Blue and yellow combine to make green.
Adenosine, ribose sugar, and a chain of three phosphate groups combine to form an ATP molecule.
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.
When two oxygen molecules combine, they form a molecule of dioxygen (O2), which is the most stable and common form of oxygen found in Earth's atmosphere. This process is called molecular oxygen formation and involves the sharing of electrons between the two oxygen molecules to create a stable O2 molecule.
They form an embryo
When two or more atoms combine, they form molecules. Molecules are the smallest unit of a chemical compound that retains the chemical properties of the compound.
Three molecules of hydrogen will combine exactly with one molecule of nitrogen to form two molecules of ammonia (NH3) in a balanced chemical reaction.
phospholipids and proteins
A synthesis reaction.
"polymerization"
No, atoms combine to form molecules. Molecules are made up of two or more atoms bonded together through chemical bonds. Atoms are the basic building blocks of matter and cannot be broken down into smaller particles, whereas molecules can be broken apart into their constituent atoms.
