Bio 12 Enzymes
| Term | Definition |
|---|---|
| Activation Energy | The least amount of energy needed for a chemical reaction to take place. Some elements and compounds react together naturally just by being close to each other, and their activation energy is zero. |
| biochemical reaction | Chemical reactions taking plce in biological systems - animals and plants are called biochemical reactions. They follow all the laws of chemistry but are generally very fast and more efficient than reactions done in lab. |
| coenzyme | a non protein compound that is necessary for the functioning of 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 | a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. |
| enzyme activity | the catalytic effect exerted by an enzyme, expressed as units per milligram of enzyme (specific a.) or as molecules of substrate transformed per minute per molecule of enzyme ( |
| enzyme concentration | Enzyme concentration is the level of enzymes in the body |
| heavy metal | A metal of relatively high density (specific gravity greater than about 5) or of high relative atomic weight.Any element with an atomic weight greater than twenty (twenty times the weight of hydrogen) |
| 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 | a non protein compound that is necessary for the functioning of an enzyme. |
| non-competitive inhibitor | 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. |
| pH | a measure of the hydrogen ion concentration of a solution |
| substrate concentration | a substance or layer that underlies something, or on which some process occurs. |
| thyroid | a two-lobed endocrine gland found in all vertebrates. |
| thyroxin | principal function is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues in the body |
| vitamins | A vitamin is an organic compound required by an organism as a vital nutrient in limited amounts. |
