between 3-7 carbohydrate molecules attached together to form a chain. Two monosaccharides can be combined to form a larger carbohydrate molecule called a disaccharide. Polysaccharides are the largest of all the three combinations of carbohydrate molecules. Glucose and fructose are two examples of monosaccharides‚ and sucrose (table sugar) is a disaccharide because it can be formed by the combination of glucose and fructose molecules. Glycogen and starch are

that when put together create carbon compounds‚ and polymers are molecules that consist of repeated units. b. Functional groups are made of clusters of atoms‚ while macromolecules are large polymers. c. A monosaccharide is a simple sugar‚ but a disaccharide is known as a double sugar‚ or two monosaccharaides. d. Long chains of amino acids are called polypeptides‚ and proteins are composed of one or more of them. e. Nucleic acids are composed of thousands linked monomers called nucleotides. 2) a.

lactase which is an enzyme that catalyzes the hydrolysis of lactose sugar into glucose and galactose as shown in the following reaction: C12H22O11 + H2O C6H12O12 + C6H12O12 Lactose is the disaccharide found in milk‚ and it requires lactase enzyme for proper digestion. To study lactase kinetics: first‚ we constructed a standard curve for Ortho- Nitrophenyl (ONP)‚ by plotting the absorbance vs number of moles in the standard samples. Then‚ we

enzymes amylase is denatured by temperatures above 60°C. The enzyme used in this lab exercise is amylase‚ which is commonly found in saliva and germinating seeds. It catalyzes the breakdown of starch. When amylase reacts with starch‚ it cuts off the disaccharide maltose (two glucose molecules linked together). As the reaction progresses‚ less starch will be present and more sugar (maltose) will be present. In lab‚ the activity of amylase was observed by using iodine. Remember‚ iodine reacts with starch

Final Biology Exam Review Unit One: Cellular Processes Definitions: Apoptosis – Known as cell suicide‚ lysosomes break open and decompose the entire cell. Triglyceride – A lipid molecule composed of glycerol and three fatty acids. Simple diffusion – Movement of particles from an area of high concentration to an area of low concentration. It goes through the phospholipid bilayer. Facilitated diffusion – Diffusion of particles through the cell membrane‚ assisted by transmembrane proteins

We hypothesized that coconut milk would contain all four types of macromolecules‚ karo syrup would only contain simple sugars which are monosaccharides and/or disaccharides‚ potato chips would contain starches and fats‚ peanut butter would contain sugars‚ fats‚ and proteins‚ and banana baby food would consist of sugars and starch. Each macromolecule test consisted of five test tubes of the food item individually
