Ch 16 #1: Please answer the following about the Primary versus Secondary Response Which response would be more affected by a lack of memory B and memory T cells: the primary or the secondary immune response? Definitely the Secondary response. During the Primary immune response when the B cells and T cells are activated from an encounter with an antigen‚ plasma cells release antibodies to destroy the antigen. During the proliferation phase some of the cells produced stay dormant and act as

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

4-nitroaniline had a percent recovery of 18.67% and naphthalene had a percent recovery of 80%. Naphthalene had a relatively high percent recovery‚ and the loss of product can be explained by error inherent. The low percent recovery of 4-nitroaniline is mainly due to the fact that anhydrous sodium sulfate was accidently added to the flask. Therefore‚ some product was lost as the aqueous solution with the protonated 4-nitroaniline reacted with the drying agent. However‚ more errors to explain the results

unimolecular dissociation step‚ a proton from one of the adjacent carbons is captured to reform the acid catalyst‚ and the elimination reaction is complete with the formation of the double bond. Water is distilled out of the reaction to promote a high yield of 4-methylcylohexene. By removing water‚ the reaction is forced in the forward direction due to Le Châtelier’s Principle.

Results and Discussion: A reaction involving two bond formation was employed for the preparation of 3‚5-disubstituted 1‚2‚4-triazole as nucleobase analog. The hydrazides 2a‚b were allowed to react with the heteroaryl substituted acetonitrile derivatives 1a-c using catalytic amount of K2CO3 and n-butanol as a solvent to afford the disubstituted 1‚2‚4-triazoles 3-7 bearing benzothiazole‚ benzotriazole‚ quinoloxymethyl and benziimidazole ring systems in moderate yields.
