Mutations That Result In Single Amino Acid Substitutions In An Enzyme

A) can have no effect on the activity or properties of the enzyme B) will almost always destroy the activity of the enzyme C) will often cause a change in the substrate specificity of the enzyme D) may affect the physicochemical properties of the enzyme such as its optimal temperature and pH E) may, in rare cases, cause the enzyme to run reactions in reverse

D) ? Mutation-->permanent change in a gene, can result in a protein with one or more changed amino acids. If the changed amino acid is in the active site or a crucial region, then the altered enzyme might have a novel activity or might bind to a different substrate, when this happens and it benefits the organism under environmental conditions natural selection will favor the mutated form of the gene Activity of an enzyme (how efficiently the enzyme functions) is effected by environmental factors such as temperature and pH and chemicals that specifically influence that enzyme

About the flashcard:

This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group. The cards are meant to be seen as a digital flashcard as they appear double sided, or rather hide the answer giving you the opportunity to think about the question at hand and answer it in your head or on a sheet before revealing the correct answer to yourself or studying partner. Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers. Simply reveal the answer when you are ready to check your work. Absolutely no cheating is acceptable.
