SLS Bio 12Enzyme(SA
| Question | Answer |
|---|---|
| Activation Energy | Energy that must be added to cause molecule to react with one another. |
| biochemical reaction | Process in which two or more molecules interact with help of an enzyme and make a product. |
| coenzyme | nonprotein organic molecule that aids the action of the enzyme to which it is loosely bound |
| competitive inhibitor | Form of enzyme Inhibition, where an inhibitor binds to the active site so that the substrate will not fit in the active site properly there for will ont work. |
| enzyme | organic catalyst, usually a protein, that speeds up reation in cell due to its particular shape |
| 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 | Effects the rate of product formation during an enzyme reaction. The higher the concentations, the higher the rate. |
| heavy metal | Are inhibitors to an enzymes. They disrupt the normal distribution of electorns in the enzyme. Therefor decreasing enzyme activity. |
| induced fit model | Change in the shape of an enzymes active site that enhances the fit between the enzymes active site and its substrates |
| metabolism | All of the chemical changes that occur within a cell controled by enzymes. |
| non-competitive inhibitor | A non-competative inhibitor is something that changes the shape of the enzyme temporarly. They bond to a spot that changes the active site shape there for it can not function. |
| pH | Measurement of the amount of hydrogen ions in a solution.Measuring them as a base if they are bigger that 7 and an acid if they are lower than 7. |
| substrate concentration | The amount of substrates in a solution where enzyme activity occurs. Effects the rate of formation, rate increased. |
| thyroid | Located in the neck region, produces thyroxin. |
| thyroxin | Hormone that accelerates cell metabolism. People with low thyroxin are overweight and have little energy. |
| vitamins | Asssists enzyme functions. There are many types that will effect and help different enzymes. They are absorbed with food nutrients. |
