BIOD 171 ESSENTIAL MICROBIOLOGY FINAL EXAM 183 PRACTICE QUESTIONS AND ANSWERS BIOD 171 ESSENTIAL MICROBIOLOGY FINAL EXAM GRADED A What various functions do proteins have in a cell Proteins may facilitate the movement of materials in or out of a cell. Some can act as enzymes that catalyze, or speed up, biochemical processes. Others play a structural role while other proteins, such as filaments, enable movement. What are the main morphologies of bacteria? Bacteria can be described as coc...

What is cellular metabolism? - a controlled set of biochemical reactions that occur in living organisms in order to maintain life What is an enzyme? - a protein, or group of proteins, that catalyze (speed up) chemical reactions What is unique about enzymes? - the enzyme is not consumed during the reaction and can be used repeatedly by the cell What is a cofactor? - a small chemical component, usually metal ions, that assist enzymes during the catalysis reactions Do cofactors serve as regu...

van der Waals correct answer: -weakest (short lives) but lots could strengthen the bond -furthest distance -form as a result of hydrophobic interactions -strength depends on the size of the atoms and the distance between them -cannot be closer than the Van der Waals contact distance or else positively charged nuclei will repel each other (energy= 0) Proteins correct answer: main action molecule of the cell (Most chemical processes of the body are carried out by proteins) -classified in...

cellular metabolism a controlled set of biochemical reactions that occur in living organisms in order to maintain life enzyme a protein, or group of proteins, that catalyze (speed up) chemical reactions/is not consumed during the reaction and can be used repeatedly by the cell cofactor a small chemical component, usually metal ions, that assist enzymes during the catalysis reactions/serve as regulators of chemical reactions: in their absence, enzymes are inactive while in its presence enzy...

UNIT 1 - Quizzes and Exam, UNE medical biochemistry Unit 1 Test Correctly Answered To Score A+ Which of the following amino acid would not be commonly found in the middle of a an α-helical domain? Proline. It is considered a 'helix breaker' and would not be found in an alpha helix; all other residues are nonpolar hydrophobic and could reside in a transmemebrane domain. Changes in the physiological variables listed below can alter the affinity of hemoglobin for oxygen. Which of the fol...
