Sir Safar Lecture 2 Finals Pentose Phosphate Pathway (S. 70) Alternative pathway for glucose oxidation. Similar to glycolysis‚ but instead of having pyruvate as the end product it is diverted to other pathways. Supplier of energy to the cell in the form of NADPH (a reducing power for biosynthesis). It is also referred to as hexose monophosphate shunt. *Fate of glucose 6-phosphate (G 6-P) IN THE PPP (S. 71) Taken out from glycolysis and converted into Ribulose 5-phosphate. With the conversion

Living organisms are composed of part water and part chemicals. The chemicals that help make up life are constructed mainly of carbon. A compound that has carbon in its composition is called an organic compound. Organic compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size

Chemistry questions COPY AND PASTE INTO A WORD DOCUMENT 1. What information would you need to calculate the atomic mass of an atom? The atomic number‚ the number of neutrons and add the numbers together. This is the atomic mass. 2. What information would you need to determine the atomic number of an atom? The number of protons in the nucleus of the atom. 3. Chlorine (Cl) has 17 electrons‚ 17 protons‚ and 18 neutrons what is the atomic mass of Cl? 34 4. What is the charge of the

These food molecules‚ after its been broken down‚ will diffuse away from your small intestines and into your bloodstream which will have steep concentration gradient. The blood compared to the nutrients like glucose‚ amino acids‚ fatty acids and glycerol will have a higher concentration. Diffusion can happen thoroughly as possible because of the villi that can be found on small intestine that gives it a more larger surface

added to it. B. How would you determine the melting of a substance whose melting point is higher than 100°C? *Another substance other than water in the beaker would have to be used to see melting point that would be higher than 100 ⁰ C such as glycerol or silicon oil. C. What would be the effect of increasing the amount of crystals in the capillary tube? *There would be no difference if the amount of crystals were in the capillary tube because the melting point is still at the same temperature

PNGase F Procotol Reactions may be scaled-up linearly to accommodate larger amounts of glycoprotein and larger reaction volumes. Optimal incubation times may vary for particular substrates. Typical reaction conditions are as follows: Denaturing Reaction Conditions: 1. Combine 1-20 µg of glycoprotein‚ 1 µl of 10X Glycoprotein Denaturing Buffer and H2O (if necessary) to make a 10 µl total reaction volume. 2. Denature glycoprotein by heating reaction at 95°C for 5 minutes. 3. Chill denatured glycoprotein
