| Term | Definition |
|---|---|
| activation energy | the energy required for a reaction to occur |
| biochemical reactions | this is a process where two or more enzymes react with each other usually with the help of an enzyme |
| coenzyme | a molecule that provides the transfer site for biochemical reactions catalyzed by an enzyme. |
| competitive inhibitor | Competitive inhibition is a form of enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa |
| enzyme | Enzymes are complex proteins that cause a specific chemical change in all parts of the body. |
| enzyme concentration | enzyme concentration is the amount of enzyme you can have in a solution |
| enzyme activity | the catalytic effect exerted by an enzyme, expressed as units per milligram of enzyme or as molecules of substrate transformed per minute per molecule of enzyme |
| heavy metal | metal with a high specific gravity, typically larger than 5; e.g., fe, co, cu, Mn, mo, zn, v. |
| induced fit model | A model for enzyme-substrate interaction to describe that only the proper substrate is capable of inducing the proper alignment of the active site that will enable the enzyme to perform its catalytic function. |
| metabolism | the chemical processes that occur within a living organism in order to maintain life. |
| non competitive inhibitor | Non-competitive inhibition is a type of enzyme inhibition where the inhibitor reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate |
| substarte | A substrate is the medium in which a chemical reaction takes place or the reagent in a reaction that provides a surface for absorption. |
| substrate concentration | substrate concentration is the concentration of the molecules an enzyme works on. |
| thyroid | a large ductless gland in the neck that secretes hormones regulating growth and development through the rate of metabolism. |
| thyroxin | the main hormone produced by the thyroid gland, acting to increase metabolic rate and so regulating growth and development. |
| vitamin | any of a group of organic compounds that are essential for normal growth and nutrition and are required in small quantities in the diet because they cannot be synthesized by the body. |
| ph | A measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity. The pH scale commonly in use ranges from 0 to 14. |
