Only the enzyme will fix the substrate because of the active sites on the enzyme. Once locked together, the enzyme can break down the substrate (Hudon-Miller, 2012c). An example of this is Sucrose. Sucrose is considered a regular table sugar. It is composed of two monosaccharaides: glucose and fructose.
Calculate the number of grams of glucose needed to prepare 100mL of a 280 msm/L glucose solution. (280mOsm/L)*(1L/1000mL)(100/1)*(120mg/1mosm)*(1g/1000mg)=5.04g Based on your calculation a 0.812% NaCl solution (w/w) and a 5.04% glucose (w/w) solution are isotonic to normal human cells. In medical professions clinicians consider a 0.9% NaCl and a 5% glucose solution is isotonic to normal human
P2: Describe the characteristics of nutrients and their benefit to the body. Answer: Characteristics of nutrients and their benefit to the body are carbohydrates, starch and non-starch polysaccharides, sugar substitutes and sugar. Carbohydrates are one of the main types of food. Sugar and starch are main types of carbohydrates these carbohydrates provide energy for the body. Liver breaks down carbohydrates into glucose which the body uses for sugar.
12: Hydrolysis reactions ARE EXOTHERMIC 13: If a molecule is described as "organic," this means it CONTAINS CARBON AND HYDROGEN 14: Glucose is a sugar with six carbons. This makes it a HEXOSE Hexoses (sugars with six carbons), such as glucose, play a vital role in the metabolism of all cells. 15: A proton is an atomic particle with a POSTIVE CHARGE 16: Pasteur made major contributions to the study of which of the following? FERMENTATION 17: Which of the following is NOT associated with the structure of fats? PEPTIDE BONDS 18: Members of which of the following groups are
Sucrose is used to sweeten foods, and provide short term energy. In sodas such as the orange soda and clear soda used during this lab, the sugar is used to sweeten the drink. Density can be used in order to find the sugar concentration in a particular solution. Density is known as the amount of mass that will fit into a certain volume. For this lab, the density of water will be 1 gram/cubic centimeter.
The Role of Fat and it's importance in our diet !1 LIPIDS • Lipids are non soluble molecules that include fats, waxes, sterols, & phospholipids. Lipids main function is storing energy, sending chemical messages in cells, and are components in cell membranes. Lipids make up adipose tissue which is a connective tissue that is made up of lipid cells called adipocytes. Lipids can also be metabolized leading to a large amount of ATP (energy in the body) production. When Lipids are broken down they are broken into a glycerol molecule and fatty acids.
* Cellulose as a source of chemicals – starch, another polymer of glucose, can be used as an alternative source for petrochemical products but there is more cellulose produced in plants than starch. Each glucose unit of cellulose has 6 carbons atoms joined together, a good starting point in making petrochemicals e.g. ethylene (2 C atoms). However, it is more difficult to break cellulose into glucose than starch due to the many hydrogen bonds in the long near-linear chains of cellulose forming compact fibres. There are two processes to break cellulose into
Lactase Buffer solutions 4,7,9 Enzymes are organic catalysts that control the rate of chemical reactions in cells while not being permanently altered themselves. In general, enzymes speed up the rate of reaction by lowering the activation energy required to start reactions. Lactase is an enzyme used by the body to hydrolyze lactose, a disaccharide unique to mammalian milk, into the monosaccharaides, glucose and galactose. Lactose has been shown to aid in the absorption of several minerals, including calcium, magnesium, and zinc. .
Ionic Bond 13) Name the four main classes of biological molecules and their monomers First main class of biological molecules is carbohydrates, monomers are energy, glucose and structure. Second class is lipids, monomers high energy, storage, cell membrane, butter vegetable oil and cholesterol Third is proteins, monomers structure, enzymatic and amylase and Fourth main biological class of molecules are Nucleic acids, monomers nucleotides, hereditary code ,energy carrier, DNA and ATP 14) Briefly describe the following types of bonds: * Covalent Bond Covalent Bond is the stronger bond in nature. What happens in covalent bond is that the atoms are sharing electrons so each shell has the maximum numbers of electrons that they need. * Ionic Bond Ionic Bond does not share electrons like covalent bond it transfer the electrons to an another atom so it can reach the maximum number of electrons in the shell. * Hydrogen Bond Hydrogen Bond is the attraction between partial charges it holds the biological molecules together.
The three more significant forms of sugar are sucrose, glucose, and fructose. Sucrose, mass-produced by processing sugar cane or beet sugar, is the white table sugar that people add to various foods or drinks to increase their sweetness. Glucose can be recognized more frequently than either sucrose or fructose because of its involvement in diabetes which hampers the production of the hormone, insulin, a chemical messenger that is used to regulate glucose levels in the bloodstream. Additionally, glucose is not significantly dangerous on its own; it only becomes problematic for patients suffering from diabetes or dental cavities which are holes in one’s teeth. And without a doubt the real problem with sugar lies with fructose, it is metabolized just like the fructose in fruit, but with some significant differences.
