is the solute concentration of potatoes? We can determine this by conducting an experiment in which involves the process of osmosis. Potatoes are full of sucrose used for energy storage in plants. Sucrose is a carbohydrate found in food. It is a disaccharide‚ with a combination of fructose and glucose. Consumers break sucrose down into two monosaccharides so they can be absorbed more easily into the blood. Sucrose is too large of a molecule to diffuse through a semi-permeable membrane‚ and therefore

saliva‚ where it begins the chemical process of digestion. Foods that contain starch like rice and potatoes. Amylase turns some of their starch into sugar in the mouth. The pancreas makes amylase (alpha amylase) to hydrolyze dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Alpha amylase in this lab is used to hydrolyze starch to break it down into maltose. Purpose of this lab is to show that both pH temperature affect

Cell respiration takes place in the mitochondria of animals and in the cytoplasm of plants. The formula for aerobic cellular respiration is: c6H12O6+ 6O2→6CO2+6H2O Aerobic respiration occurs when oxygen is present‚ while anaerobic respiration occurs when

Biological Molecules contain specific chemical structures called functional groups‚ which can be distinguished by biochemical tests‚ such as Benedict’s Iodine‚ and Sudan III/IV. The Benedict’s test identifies reducing sugars (monosaccharide’s and some disaccharides)‚ which have free ketone or aldehyde functional groups). The groups reduce CuSO4‚ a component of Benedicts‚ resulting in a color change in the benedicts solution from a turquoise to a brick to rusty-brown color. Another class of carbohydrates
