Portage Learning Microbiology Module 2 Exam Questions And Answers Metabolism - ANS A controlled set of biochemical reactions that occur in living organisms in order to maintain life. Enzyme - ANS A protein, or group of proteins, that catalyze (speed up) chemical reactions. It is not consumed during the reaction and can be used repeatedly by the cell. Cofactor - ANS Assist enzymes in the catalysis of reactions. Metal ions are an example. They regulate the specificity and fun...

Principles of Microbiology – Exam Questions with Correct Answers Autotrophs - Answer-Synthesize own energy (self feeders) ex: plants Heterotrophs - Answer-Ingests organic molecules (consumers) ex: animals with food Chemotrophs - Answer-Obtain carbon from inorganic substances Phototrophs - Answer-organisms that get energy from light Chemoheterotrophs - Answer-An organism that must consume organic molecules for both energy and carbon. Cause most infectious diseases - most micro...

What do cells need access to build macromolecules? carbon, nitrogen, phosphorus, sulfur, and oxygen What else do microbes need for growth? micronutrients What are micronutrients? metal ions such as zinc, cobalt, molybdenum, copper and manganese How do cells incorporate nutrients from their surroundings? assimilation What is assimilation? cells import a molecule and incorporate it into cellular constituents How do autotrophs obtain carbon? assimilate carbon from inorganic sources via carbon ...
