When a molecule absorbs a photon, it is said to be excited, or at a higher‑energy state. The excited molecule can return to its ground state when the absorbed energy is dissipated, a process that can occur by several mechanisms. Each phrase describes a mechanism by which the excited molecule releases its energy and returns to its ground state. Determine whether each phrase describes heat, fluorescence, exciton transfer (resonance energy transfer), or photooxidation.
1. The energy that has been converted to a potentially unusable form is lost as .
2. An excited molecule is oxidized and an acceptor molecule is reduced during
3. Absorbed light given off as a lower-energy photon is
4. Absorbed energy may be passed on to another molecule in a process called
