1. You are considering the following biological reactions that are catalyzed by specific enzymes as shown below. In reaction #1, enzyme El catalyzes the conversion of compound A to compound B in a truly reversible reaction in which the reverse reaction is just as likely as the forward reaction. In reaction #3, enzyme E2 catalyzes an energy requiring reaction that uses compounds C and D as substrates to produce compound E. In reaction #3, enzyme E3 catalyzes an energy producing...

2. Enzymes are important biological molecules and they act as catalysts for specific chemical reactions. Their biological function is determined by their 3 dimensional shape and the functional groups present in the active site. (a) What are the main mechanisms by which an enzyme increase the rate of a reaction? (b) What is a cofactor in an enzyme mediated reaction? (c) Give the name of a cofactor (structure if possible) and indicate the type of reaction that it facilitates. 3....

13. Describe 2 mechanisms whereby ATP is generated during cellular respiration Mechanism 1: Mechanism 2: 14. Indicate the MAIN molecules that enter and exit each of these processes? Molecule(s) IN Process Molecule(s) OUT Glycolysis Pyruvate Oxidation Citric Acid/Krebs Cycle ETC Photophosphorylation Calvin Cycle 15. Isocitrate is a 6 carbon molecule that is oxidized to a-ketoglutarate (a 5 carbon molecule) by the enzyme isocitrate dehydrogenase. What happens to the extra carbon atom in this reaction and in which process (listed in...
