| Question | Answer |
|---|---|
| Enzymes | are substances that cause chemical reactions to occur faster. |
| how do enzymes work? | Enzymes work by decreasing the amount of energy needed to activate the chemical reaction. |
| because of the reason enzymes work they are called.. | catalyst |
| without enzymes catalyzing metabolic reactions, cells would not be able to... | perform metabolism quickly enough to support life. |
| how are enzymes produced? | cell ribosomes |
| Ribosomes produce specific enzymes to act on specific substances what are they called? | substrates |
| enzymes are also important for? | the synthesis of new molecules |
| RNA polymerase is a? | enzyme that is essential to the process of transcription |
| Molecules of mRNA are ________ by RNA _______ and later new protein molecules are synthesized based on the instructions coded in the ____. | Molecules of mRNA are transcribed by RNA polymerases and later new protein molecules are synthesized based on the instructions coded in the mRNA. |
| The shape of an ______ determines how it works. | The shape of an enzyme determines how it works. |
| Most enzymes have a surface with.. | one or more deep folds |
| the folds make pockets which are called..? | active sites |
| An enzyme’s shape is ___ to how the enzyme _________. | An enzyme’s shape is key to how the enzyme functions. |
| what happens if the shape is changed? | it wont work |
| can the temperature and pH affect the shape of the enzyme's | yes |
| Therefore, enzymes are only able to work properly in a certain ______ and __ range. | Therefore, enzymes are only able to work properly in a certain temperature and pH range. |
| RNA ________ is an enzyme that is essential to the process of _________. | RNA polymerase is an enzyme that is essential to the process of transcription. |
| Can you overdose on enzymes? | uncertain |
| Enzymes are protein molecules which carry a vital energy factor needed for every ______ _______ and reaction that occurs in our body. | Enzymes are protein molecules which carry a vital energy factor needed for every chemical action and reaction that occurs in our body. |
| Again, every organ, every tissue, and all the 100 trillion cells in our body depends upon the _____ of enzymes and their energy factor. | Again, every organ, every tissue, and all the 100 trillion cells in our body depends upon the reaction of enzymes and their energy factor. |
| Again, every organ, every tissue, and all the ___ ______ _____ in our body depends upon the reaction of enzymes and their energy factor. | Again, every organ, every tissue, and all the 100 trillion cells in our body depends upon the reaction of enzymes and their energy factor. |
| energy _____ is separate and distinct from the ______ make-up of the enzymes itself. | This energy factor is separate and distinct from the chemical make-up of the enzymes itself. |
| Every organ, every tissue, and all the 100 trillion cells in our body _____ upon the reaction of _______ and their energy factor. | Every organ, every tissue, and all the 100 trillion cells in our body depend upon the reaction of enzymes and their energy factor. |
| Nutrition cannot be ______ without describing the part that _______ play. | Nutrition cannot be explained without describing the part that enzymes play. |
