In the chromatography of the reaction mixture, water absorbed on cellulose functioned as the stationary phase. What was the principal factor determining the migration of individual components in the sample? A.Hydrogen bonding B.Solute concentration C.Stationary phase concentration D.Thickness of paper B and D are dumb options. Knock them out. hydrogen bonding to the stationary phase will determine the relative rate of migration of the various components in the sample. When thinking ...

BCHE 5180 / 6180 FINAL EXAM | Graded A 1 3 points Based on what you have learned about the functioning of enzymes and proteins, explain why the pH in the cell has to be buffered. A large group of enzymes show a pH optimum for their activity. This value is normally close to the pH in the cell. When the pH in the cell changes this can lead to a protonation or deprotonation of an amino acid that is important for the enzymatic activity. As a result the activity will decrease. Upon large ch...

FSHN 101 Final Exam Study Guide Section 1: Nutrition and Health 1. Intro 2. Food: Evolution Through the Ages I. The evolution of the food system in society A. Obtaining food is a fundamen tal activity of human life B. Early humans obtained food by hunting wild animals and gathering the edible parts of plants 1. Hunters and gatherers typically lived in egalitarian (i.e., there were no social status distinctions) bands of 20-50 people 2. They spent an estimated 20 to 30 hours per week obtaining fo...
