Cellular respiration is defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka‚ Diaz and Villa‚ 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates‚ such as glucose‚ is a fundamental part of cellular respiration (Mader‚ 2009). As a catabolic process‚ it may or may not require the presence of oxygen. The process that requires oxygen is called aerobic

glucose‚ sucrose‚ and lactose. Glucose is a monosaccharide and is used in the first step of glycolysis in order to help create pyruvates‚ which are then used to create ethanol as long as there is no mitochondria or oxygen present. Sucrose is a disaccharide‚ commonly referred to as sugar‚ it’s used worldwide‚ and mainly harvested from sugarcanes. Sucrose is composed of two

atom and one oxygen atom. They are necessary for the body to function properly because they provide the fuel that burns to produce energy. Carbohydrates come in the class of either a monosaccharide‚ disaccharide‚ or polysaccharide. Monosaccharides are the simplest form of a carbohydrate‚ disaccharides are made up of two monosaccharides and‚ polysaccharides are made up of three or more monosaccharides. Common foods we consume contain each of these classes of carbohydrates. Milk and fruit contain natural

Indicate whether each of the following statements about triglycerides is true or false. Indicate whether each of the following statements about triglycerides is true or false. 1. A triacylglycerol is composed of 3 glycerol molecules joined to a fatty acid. 2. The hydrocarbon chains of fatty acids vary in length as well as in the number and location of double bonds between the carbon atoms. 3. Fatty acids with one double bond in their hydrocarbon chain are called monounsaturated‚ while those with

many people in third world nations. Potatoes are full sucrose used for energy storage in plants. Sucrose is a carbohydrate or sugar found in food. It’s a combination of fructose and glucose two simple sugars‚ making it a disaccharide. Consumers break down sucrose a disaccharide into two monosaccharide‚ so they can be absorbed easier and quicker into the blood. Without being broken down sucrose is too large of a molecule to diffuse through semi permeable membrane and wouldn’t be able move in and out
