<span>When sunlight excites electrons in chlorophyll the energy of the electrons increases. After the electrons gain energy they are taken by carrier molecules from chlorophyll to other molecules.</span>
<em>Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble.</em>
