Fats are an important energy source for humans and other creatures. Fats are broken down by the enzyme lipase to fatty acids and glycerol. If the cell is short of glucose, glycerol will be converted to glyceraldehyde 3-phosphate, one of the intermediates in the anaerobic phase of glucose breakdown called glycolysis. So you can get G3P from glucose, or from fats. G3P is then converted to pyruvic acid, which in turn enters the aerobic phase (Krebs cycle and electron transport system) of cellular respiration, once it's converted to acetyl CoA. Fatty acids are also converted to acetyl CoA,if the cell is short of pyruvic acid. Acetyl CoA is then broken down to produce ATP (the basic energy molecule). A gm of fat is converted to twice as much ATP as a gram of starch in aerobic respiration. So fats are not converted directly to glucose, but they are converted to intermediates in glucose breakdown.
