Portage Learning Microbiology Module 2 Exam Questions And Answers

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 function of some enzymes. Anabolism - ANS Building up or biosynthesis of macromolecules from smaller molecular units into much larger complexes. Catabolism - ANS Process of breaking down larger molecules into useful energy sources. Which metabolic process is involved during the growth and repair phases of the cell? - ANS Anabolism ATP vs ADP energy transfer - ANS ATP has the energy to donate a phosphate group while ADP can accept energy in the form of a phosphate group. ATP transfers energy from catabolic reactions to be used for anabolism. Phototrophs - ANS Microbes that acquire energy from photons of light to generate ATP from ADP. Chemotrophs - ANS Microbes that acquire energy from preformed chemicals in the environment (further divided into organotrophs and lithotrophs) Organotrophs - ANS Remove electrons from organic molecules (such as glucose) Lithotrophs - ANS Re
