BCHE 5180/6180: Spring Final (Graded A+) 1 3 points Based on what you have learned about the functioning of enzymes and proteins, explain why the pH in the cell has to be buffered. A large group of enzymes show a pH optimum for their activity. This value is normally close to the pH in the cell. When the pH in the cell changes this can lead to a protonation or deprotonation of an amino acid that is important for the enzymatic activity. As a result the activity will decrease. Upon large chan...

Exam (elaborations) TEST BANK FOR The Art of Writing Reasonable Organic Reaction Mechanisms 3rd Edition By Robert B. Grossman (Solution Manual) sp2 hybridization. One of the lone pairs is in a p orbital, and the other is in an sp2 orbital. Only the lone pair in the p orbital is used in resonance. 1.5. (a) No by-products. C(1–3) and C(6–9) are the keys to numbering. (b) After numbering the major product, C6 and Br25 are left over, so make a bond between them and call it the by-product....

1. A decrease in the temperature of a gas sample in a closed container will always result in an increase in the: A. value of the PV / (RT) ratio. kinetic energy of individual gas molecules. C. gas pressure on the container. D. attraction between gas molecules. Correct Explanation: D. Since the temperature of a gas is proportional to the average kinetic energy of its molecules, decreasing the temperature will result in a decrease in kinetic energy. This decrease in kinetic energy will ...

Amino Acids Found in Proteins • Amino acids contain two functional groups, an amino group (-NH2) and a carboxyl group (-COOH) which are formed on a carboxylic acid. o Alpha amino acids are those where both functional groups are attached to the same carbon. o Side chain/R group and hydrogen atom are also attached to alpha carbon.  Side chain determines the properties of amino acids and its functions. Terminology • There are a variety of different types of amino acids, however the MCA...
