What is the active site of an enzyme binds the products of enzyme catalyzed reactions and holds them there with weak chemical bonds? Enzymes: The chemical molecules found in the body that enhances the rate of biochemical reactions are ref...
This is called catalysis, so enzymes are catalysts. How do enzymes work An enzyme is a large molecule but only a small part of the molecule is involved in catalysis. This part is called the active site. Each enzyme has a specific function; to break down a specific substance. This is ...
(a) What is the structure of myosin? (b) What is the structure of actin? The Sarcomere: The smallest contractile unit of the muscle is called the sarcomere. This structure is composed of actin and myosin filaments that bind and shorten during muscle contraction. These filaments have e...
Penicillin, for example, is a competitive inhibitor that blocks the active site of an enzyme that many bacteria use to construct their cell… …the substrate usually combines (competitive inhibition) or at some other site (noncompetitive inhibition). What drugs are competitive inhibitors? An example...
ST elevation myocardial infarction". The ambulance attendant tells him that he is having a large heart attack which is potentially life-threatening and is being caused by an acute blockage of a major coronary artery by a blood clot that had formed on top of an unstable blockage of cholesterol...
Skincare ingredients such as vitamin C, liquorice, azelaic acid and kojic acid, which all inhibit the action of an enzyme called tyrosinase. These help to stop the skin from making so much pigment in the first place, as this enzyme is vital to the process. ...
A genetic mutation in the viral genome can produce an altered version of this active site. The drug may then not be able to bind to the site and block the enzyme. Another HIV drug resistance mechanism is to alter the structure of a drug to render it useless. For example, a drug may ...
What is the structure of an enzyme? Enzymes structure are made up of α amino acids which are linked together via amide (peptide) bonds in a linear chain. This is the primary structure. The resulting amino acid chain is called a polypeptide or protein. What is the purpose of an enzyme?
What enzyme catalyzes DNA synthesis? Key is to lock as what is to enzyme? What are the constituent parts of proteins? Which enzyme breaks down maltose? What kind of organic molecule is an enzyme? What type of macromolecule is an enzyme?
Briefly describe the three types of chemical inhibition of enzyme activity. Which of these are used in the cell to control enzymatic activity and why? What is an enzyme reaction? What are the characteristics of enzymes? What is the reactant of an enzyme-catalyzed reaction called?
