enzymes =D

unit 1, biology

QuestionAnswer
How do enzymes catalyze reactions? by lowering the activation energy required for the reaction to occur
True or False: Enzymes start chemical reactions. FALSE. Enzymes don't start reactions- they SPEED UP reactions that would occur eventually.
Substrate The reactant that an enzyme acts on
The enzyme binds to its substrate, forming what? Enzyme-substrate complex
What is the active site? The active site is the region on the enzyme where the substrate binds.
True or false: Enzymes fit with any shape of molecules. FALSE. Each substrate/reactant has a unique shape. The have a specific substrate the work on
An enzyme's activity can be affected by what three factors? Temperature, pH and Concentration of the Substrate
Each enzyme has an optimal _________ and _________ in which it can function. Temperature / pH
The names of enzymes mostly end in " ASE" ex) Protease
Activation Energy The energy required to initiate a reaction.
Optimal Enzyme Temperature Graph The temperature at which each enzyme specifically works at. In this graph it is 37 degrees C or 98.6 degrees F.
Denature (verb) The protein no longer functions due to a change in shape. Caused by extreme temperature and changes in pH.
Lock and Key Model Enzymes are specific. The only work on the substrate that they "fit." Just like a lock has a specific key to open it.
Enzyme Substrate Complex Know this diagram (just like the one we reviewed in class.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
