MICROBIOLOGY PORTAGE LEARNING EXAM 2 QUESTIONS WITH COMPLETE SOLUTIONS What is metabolism? A controlled set of biochemical reactions that occur in living organisms in order to maintain life. What are enzymes? Enzymes are proteins that catalyze chemical reactions. What is a cofactor? A cofactor is a small chemical component that assists an enzyme during the catalysis reactions. A cofactor is usually metal ions. Define anabolism. Anabolism is the process of building up or biosynthesis of...

PORTAGE MICROBIOLOGY EXAM #3 QUESTIONS WITH COMPLETE SOLUTIONS VERIFIED GRADED A+ What is the total magnification of a sample imaged with a 60x objective and a 10x eyepiece? (short answer) 60 x 10 = 600x magnification True or False: A cell that is adherent, flat, and unstained is easily identified using bright field microscopy False. Adherent, flat cells are almost invisible due to the limits on both resolution and contrast Which of the following could be seen clearly by the unaided eye? (m...

MICROBIOLOGY - PORTAGE MODULE 5 PATHOGENIC MICROBES EXAM QUESTIONS WITH COMPLETE SOLUTIONS VERIFIED GRADED A+ When must universal precautions be taken? When an unknown biological sample arrives in the lab for assessment and further characterization Define the practice of universal precautions. The practice of universal precautions means any and all samples, whether known or unknown, are to be treated as potentially hazardous (or pathogenic) materials. What must you use when you are prac...
