5. a) What is enzyme is responsible for nitrogen fixation? What are the components of the enzyme complex involved? What is the function of these components? Nitrogenase is the enzyme involved. It is inactive in the presence of O2. b) Nitrogenase is extremely sensitive to oxygen and requires an anaerobic environment. Yet, S. meliloti is an obligate aerobe and the plant tissue needs oxygen. How is this requirement achieved in the Rhizobium:legume symbiosis?

(a) Explain the importance of enzymes in biological systems. (b) What chemical transformations are catalyzed (i) by the enzyme catalase, $(i i)$ by nitrogenase? (c) Many enzymes follow this generic reaction mechanism, where $\mathrm{E}$ is enzyme, $\mathrm{S}$ is substrate, ES is the enzyme-substrate complex (where the substrate is bound to the enzyme's active site), and $\mathrm{P}$ is the product: 1. $\mathrm{E}+\mathrm{S} \rightleftharpoons \mathrm{ES}$ 2. $\mathrm{ES} \longrightarrow \mathrm{E}+\mathrm{P}$ What assumptions are made in this model with regard to the rate of the bound substrate being chemically transformed into bound product in the active site?
Enzyme A is a multisubunit protein (i.e multiple polypeptide chains in a stable complex) that transforms substrate molecule X into product molecule Y. Part A. Enzyme A is inhibited by normal cellular metabolites B and C. B is chemical similar to X and inhibits the enzyme by competing with X for binding to the active sit. C inhibits the enzyme by binding to a "regulatory" subunit in the complex that has no catalytic activity. Are these examples of allosteric regulation? Explain, for each, why or why not. Part B. Enzyme A is also regulated by phosphorylation. When it is phosphorylated its Km is increased by a factor of 3. Assuming that the concentration of the substrate in the cell is close to the Km for the unphosphorylated enzyme, does phosphorylation activate, or inhibit, the enzyme?
