Enzymes MS

QuestionAnswer
Enzymes are substances that cause chemical reactions to occur faster
Enzymes work decreasing the amount of energy needed to activate the chemical reaction
substrates Ribosomes produce specific enzymes to act on specific substances
active sites The folds make pockets
enzyme functions An enzyme’s shape is key to how
If its shape is changed the enzyme may not function as well or at all
temperature and pH can affect the shape of an enzyme’s active sites
enzyme that is essential to the process of transcription RNA polymerase
Molecules of mRNA are transcribed RNA polymerases
Most enzymes are proteins
Enzymes are also important for synthesis of new molecules
Most enzymes have a surface with one or more deep folds
catalyst. Many of the chemical reactions that occur in cells are catalyzed enzymes
Most enzymes are proteins
the enzyme catalase assists in the breakdown of hydrogen peroxide into water and oxygen.
hydrogen peroxide is catalase’s substrate.
Enzymes are also important for the synthesis of new molecules.
RNA polymerase is an enzyme that is essential to the process of transcription
The active sites match folds in the substrate’s surface
particular enzyme fits against its substrate like two adjacent puzzle pieces.
If its shape is changed the enzyme may not function as well or at all.
Molecules of mRNA are transcribed by RNA polymerases and later new protein molecules are synthesized based on the instructions coded in the mRNA
Therefore, enzymes are only able to work properly in a certain temperature and pH range. temperature and pH can affect the shape of an enzyme’s active sites
An enzyme’s shape is key to how the enzyme functions.

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.
