Microbiology Exam 2 Study Set - Rio Salado Test Questions And Answers Verified 100% Correct what is found in the retro-viridae family? - ANSWER -reverse transcriptase Denature - ANSWER -unraveling of protein Glycolipid - ANSWER -acts as an identification tag Ester linkage - ANSWER -bond found in fats Amino - ANSWER -functional group found in proteins Metabolism - ANSWER -refers to the total of all reactions occurring in a cell Exergonic reaction - ANSWER -release of energy through catabolism which fuels endergonic reactions Endergonic reactions - ANSWER -consume energy to synthesize polymers to monomers Energy - ANSWER -capacity to do work Mechanical work - ANSWER -any form of movement ranging from the movements of the entire organism or movement of molecules in the cell Chemical work - ANSWER -breaking and building of molecules which involve the rearrgning of atoms Transport work - ANSWER -movement of a molecule across a membrane Catabolic - ANSWER -metabolic, process of doing work, ATp becomes ADP, breaking polymers to monomers, energy producing reactions breaking down of molecules; a process releasing hydrogen and electrons that determine the final acceptor of these at the end of a process. Anabolic - ANSWER -metabolic, building polymers from monomers, formation og atp, storing energy for work, energy using reactions cellular respiration - ANSWER -oxygen is consumed, carbon dioxide is expelled. The purpose is to bank as much ATP as possible Chemiosmosis - ANSWER -requires: hydrogen ions, ATP synthease enzyme, and a membrane. ATP synthase is an enzyme that cataluze the reaction of phorphrlating the ADP, creating ATP. Electron transport chain: - ANSWER -protein channels used to pump hydrogen ions from inside to the outside of the membrane True or False: cellular respiration is a series of oxidation-reduction reactions. - ANSWER -True Glycoloysis - ANSWER -first step in oxidation of glucose to relase hydrogen and electrons. - Acetyl CoA: a modifcation of pyruvate that will enter the krebs cycle Kreb cycle: - ANSWER -results in the compete oxidation of glucose Anaerobic - ANSWER -process that does not require oxygen NAD and FAD - ANSWER -molecules that carry electrons and hydrogens to the ETC Enzymes - ANSWER -control chemical reactions Catalyst - ANSWER -ignitor that gets processes started Active site: - ANSWER -where the activity of action on the substrate is going to occur Substrate - ANSWER -the molecule that is going to be acted upon and made the change for the reaction to occur Activation energy: - ANSWER -energy required to make these molecules become unstable ad react with another molecule or breakdown Coenzymes - ANSWER -organic enzyme helpers that are vitamins Cofactors - ANSWER -inorganic enzyme helpers are minerals Feedback inhibition: - ANSWER -the product of an enzymatic pathway will temporarily inhibit its pathway by becoming a noncompetitive inhibitor Competitive inhibitor - ANSWER -will permanently out-compete the substrate for the active site, which will stop the production of the product Exoenzymes - ANSWER -secreted from the cell hydrolyze large polymers into smaller polymers that can pass into the cell Amylase - ANSWER -amly= starch, the enzyme that breaks starch into smaller saccharides Lipase and protease: - ANSWER -enzymes hydrolyze lipids and proteins Oxygenic photosynthesis: - ANSWER -a byproduct of photoautotrophic organisms providing oxygen Chemoautotrophs - ANSWER -make their food using chemical energy Heterotrophs - ANSWER -feed on organisms that make their own good
