are the only foods derived from animals that contain a significant amount of carbohydrates. Carbohydrates are divided into two groups‚ simple carbohydrates and complex carbohydrates. Simple carbohydrates‚ sometimes called simple sugars‚ include fructose (fruit sugar)‚ sucrose (table sugar)‚ and lactose (milk sugar)‚ as well as several other sugars. Fruits are one of the richest natural sources of simple carbohydrates. Complex carbohydrates are also made up of sugars‚ but the sugar molecules are

Lab 04: Sugar Respiration in Yeast Sugars are vital to all living organisms. The eukaryotic fungi‚ yeast‚ have the ability to use some‚ but not all sugars as a food source by metabolizing sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. The decomposition reaction that takes place when yeast breaks down the hydrocarbon molecules is called cell respiration. As the aerobic respiration breaks down glucose to form viable ATP‚ oxygen gas is consumed and carbon
