Question

3 pts. 35) With respect to the properties of an enzyme, how does the active site differ from an allosteric 8 pts 35) The following diagram depicts the stractural organization of a gram negative bacterium. Name each of the structures identified in this figure c. D. H. 6 Bacteria are capable of utilizing a varicty of carbohydrates as carbon and energy sources You are studying the properties of an obligate anacrobe, and wish to determine its energy generating capabilities, when grown on a variety of carbon sources. You have characterized its electron transport chain and determine that this obligate anacrobe can only use SO,- as a terminal electron accepsor. You also learn that its electron transport chain is less efficient than one found in an acrobic organism, in that it is only able to generate 2 molecules of ATP for each NADH that is oxidized, and I molocule of ATP for cach FADH is oxidized. 4pts Predict how many ATP this anacrobe would generate from I molecule of glacese? Use the table on the last page to help you through the metabolic pathways pts Could this organism grow anacrobicaly with succinate in the growth medium as a sele carbon and eergy source? Justify your answer.

Explanation / Answer

Ans 35 :

Active site is the region in the enzyme wherein substrate binds to the enzyme and undergoes a chemical reaction.

Substrate binds to this site and forms an enzyme-substrate (ES) complex, which can eventually be converted into product molecule and enzyme is released free .

The allosteric site is the site of enzyme , where the molecule binds so that the confuguration of active site changes , and enzyme is no longer effective for catalysis.
