Traditionally, simple carbohydrates are believed to be absorbed quickly, and therefore to raise blood-<answer>glucose</answer> levels more rapidly than complex carbohydrates. This, however, is not accurate. Some simple carbohydrates (e.g., fructose) follow different metabolic pathways (e.g., fructolysis) that result in only a partial catabolism to <answer>glucose</answer>, while, in essence, many complex carbohydrates may be digested at the same rate as simple carbohydrates. Glucose stimulates the production of insulin through food entering the bloodstream, which is grasped by the beta cells in the pancreas.
When simple carbohydrates undergo metabolic pathways, what do they result in after partial catabolism?
glucose
