A covalent bond is formed when two atoms share electrons to achieve a stable electron configuration.
Carbohydrates, such as glucose, are the primary energy source because they are quickly metabolized during cellular respiration.
A neutral solution has a pH of 7, which means the concentration of H⁺ ions is equal to that of OH⁻ ions.
Proteins are composed of amino acids linked together by peptide bonds.
Carbon's ability to form four covalent bonds makes it the backbone of organic compounds.
