Cells break down fat molecules primarily during a state of fasting, low carbohydrate intake, or intense exercise. In these conditions, the body activates lipolysis, the process where triglycerides stored in fat cells are converted into free fatty acids and glycerol for energy. Hormones such as glucagon and epinephrine play a key role in signaling this breakdown. Additionally, conditions like ketosis, often associated with ketogenic diets, also promote fat metabolism.

Ultra violet radiation does this all the time to DNA molecules. Thymine dimers are the result of this radiation on epidermis cells.

I believe that is fermentation.
When living cells break down food molecules, energy is released in the form of ATP (adenosine triphosphate). This process is known as cellular respiration and occurs in the mitochondria of the cell. ATP is the main energy currency of the cell and is used to power various cellular processes.

Enzymes are the special proteins that can break down large molecules into smaller molecules. These biological catalysts speed up chemical reactions in cells by lowering the activation energy required for the reaction to occur.
