Summary Introduction
To write:
The difference between assimilatory and dissimilatory nitrate reduction.
Introduction:
Nitrogen is the basic component of DNA and proteins. Nitrogen exists in two oxidation states, five and three, which are interconverted in the nitrogen cycle. In this process of interconversion, bacteria play a very crucial role. There also occurs incorporation of ammonia into DNA and proteins.

implicated in the biosynthesis of tryptophan and would not grow on
minimal medium. When these bacterial mutants were tested on minimal
medium to which one of four compounds (indole glycerol phosphate,
indole, anthranilic acid, and tryptophan) had been added, the growth
responses shown in the following table were obtained.

L-lysine is being produced by Corynebacterium glutamicum in a bioreactor using glucose as the carbon source, ammonia as the nitrogen source. The bacteria grow aerobically in a continuous process at steady-state. All streams of this process are aqueous. In the inlet stream, 8 grams of glucose is included per 100 grams of stream liquid, which flows at a rate of 500 kg/h. The flow rate of glucose in the outlet steam is 1 kg/h. The reaction occurs at 25 °C.What is the mole percentage of glucose that was consumed during cell growth inside the bioreactor?Does the growth of Corynebacterium glutamicum cells inside this bioreactor release or absorbheat? Should heat be supplied to the bioreactor, or removed from, to maintain the operation temperature?

- Triclosan is a broad-spectrum antibacterial agent used in many household products. It is structurally similar to polychlorobiphenylol, a substrate that binds to the active site of the enzyme sulfotransferase. Based on these facts, you can conclude that triclosan most likely: lowers the activation energy of chemical reactions. functions as an enzyme when sulfotransferase is absent. is a competitive inhibitor. acts as a noncompetitive inhibitor.arrow_forwardUnder cellular conditions, dATP can be oxidized to its 2-hydroxy form, which is a substrate for an enzyme that converts 2-OH-dATP to 2-OH-dAMP + PPi.
