Explain your answer. Name an example of a molecule that is covalently bonded but is not polarized. Name an example of two molecules that are held together by hydrogen bonding. Considering the energy levels of the reactants and the energy levels of the products of reactions, name two types of chemical reactions. All catalysts are enzymes.
All enzymes are catalysts.
All enzymes are composed of proteins. True or False Proteins are used only as enzymes. An atom is the smallest part of an element that still retains the properties of that element. If we break the atom apart, the parts will no longer have the properties of that element. A molecule is a particle formed by the chemical bonding of two or more atoms.
