Ways of regulating enzymes - ANSWER-allosteric effector competitive inhibition noncompetitive inhibition cooperativity Competitive inhibition - ANSWER-substance the enzyme by occupying the active site Noncompetitive inhibition - ANSWER-substance inhibits the enzyme by binding to a location other than the active site and changes the shape of the enzyme Cooperativity - ANSWER-enzyme becomes more receptive to additional substrates Ribosomes are manufactures in the... - ANSWER-nucleus...

FA EMBALMING CHEMISTRY (FSE-114-0901) MODULE 5- FINAL EXAM REVIEW QUESTIONS AND ANSWERS, GRADED A+/ The active site of an enzyme and the substrate alter their shape to form an enzyme-substrate complex. This is called induced fit model Feedback inhibition regulates a metabolic pathway Enzymes will work on only one substrate. This means enzymes are specific Pepsinogen is converted to pepsin by stomach acid How do enzymes speed up chemical reactions? they lower activation energy The...

Biochemistry Questions and Answers with Verified Solutions How do cofactors assist enzymes in catalysis? Cofactors are non-protein molecules that bind to the enzyme and assist in catalyzing reactions, often by stabilizing the transition state. What is the function of the electron transport chain in cellular respiration? The electron transport chain transfers electrons through a series of protein complexes, creating a proton gradient that drives the synthesis of ATP. What are the buildi...
