SLS Bio12 Enzyme MM

TermDefinition
Activation Energy Minimum energy required by the reactant species in order for the specific reaction to take place
Biochemical Reaction Transformation inside a cell as one molecule turn into another mediated by enzymes
Coenzyme Necessary for the functioning of an enzyme but a non protein compound
Competitive Inhibitor the inhibitor binding to the active site on the enzyme prevents binding of the substrate (and vice versa) Competitive inhibitors bind reversibly to the active site of the enzyme
Enzyme organic catalyst - usually a protein - speeds up a reaction in cells due to its particular shape
Enzyme Activity a measure of ability of a given enzyme to convert its substrates into products
Enzyme Concentration concentration of enzymes, have a significant effect on how a reaction proceeds
Heavy Metal metal of high density and high atomic weight, able to denature an enzyme
Induced Fit Model substrate and active site aren't an exact fit - active site is induced and undergoes a slight change in shape to accomadate the binding of the substrate
Metabolism Chemical reactions occurring in cells which are fundamental for ATP breakdown and body functioning
Non-competitive Inhibitor An non-substrate binds to the enzyme however not filling the active site, it alters the shape of the active site therefore inhibiting the prior reaction.
pH The concentration of H+ ions in comparison to OH- Acidic is low Basic is high a pH too low or high may denature an enzyme
Substrate reactant in reaction controlled by an enzyme level
Substrate Concentration Concentration of reactants involved in the reaction.
Thyroid Endocrine gland in the neck that produces several important hormones including thryroxine, triiodithyronine, and calcitonin.
Thyroxin Hormone secreted from the thyroid gland that promotes growth and development; in general, it increases the metabolic rate in cells
Vitamins essential organic requirement in the diet, needed in small amounts, often part of co-enzymes.
