Terms like: Enzyme - Answer: A protein that catalyzes (speeds up) biological reactions Active site - Answer: An area on an enzyme where the substrate binds during a reaction; The part of an enzyme where the chemical reaction occurs. Substrate - Answer: The reactant of an enzyme-catalyzed reaction

BIO 173 Quiz 1 UMich Actual Exam/ 114 Q&A/ . Terms like: Denaturing agents - Answer: High temperatures or strong acids cause untwisting and disorganization of the protein. Common factors that affect protein conformation are temperature, pH, and the ionic composition of the solution Non-competitive inhibitor - Answer: A substance that reduces the activity of an enzyme by binding to a location remote from the active site, changing its conformation so that it no longer binds to the substrate...

BIO 173 Quiz 1 UMich Actual Exam/ 114 Q&A/ . Terms like: Cofactor - Answer: Organic molecules or metal ions attached to the active site; extra substances that are necessary for the reaction catalyzed by the enzyme Logarithmic Graph - Answer: A logarithmic graph depicts decreasing returns. In a Vmax/substrate concentration graph, as substrate concentration increases, the velocity continues to increase by a smaller amount until the velocity increase is negligible. This velocity "halt" is ...

What is a microorganism (microbe)? -microscopic unicellular organisms -not just bacterial -exist in all 3 domains (eukaryotic, bacteria, archaea) -viruses also considered microbes eukaryotes -protists and fungi -extensive membrane-bound organelles -DNA enclosed in a membrane-bound nucleus -cells are generally larger and more complex -18S rRNA Prokaryotes -bacteria and archaea -no extensive membraine bound organellses (but some bacteria still have membrane bound organelles) -no nucleus -diverse...

Microbes Microscopic single-cell organisms Can exist as a single cell or in various types of colonies or multi-cellular formations that exhibit cellular differentiation - Self-replicating bioconversion machines - drivers of many chemical conversions Why is genetic diversity important? Genetic diversity-->gene diversity-->enzyme diversity-->biochemical diversity-->biological funciton diversity Enzyme biological catalyst - lowers activation energy - not modified as a result of the re...

Microbial genomes consist of one or more DNA chromosomes Circular or linear, chromosomes or plasmids Usually one circular DNA chromosome Genome All genetic info that defines an organism Genes Contiguous packets of info encoded on chromosomes A structural gene produces a functional RNA, which usually encodes a protein DNA control sequence Regulates expression of structural gene Doesn't encode an RNA or protein Includes promoters & binding sites for regulatory proteins Ways genome is pac...
