Enzymes

Basics of enzymes

TermDefinition
Metabolism The sum of all the chemical reactions in a cell or organism
Enzyme definition A biological catalast
Biological Catalast Speeds up chemical reactions without getting used up in the reaction
Describe an enzyme’s structure A globular 3D protein
Where enzymes are made The ribosome
How enzymes are made Amino acids are joined together in a specific order.
What happens to the surface when an enzyme is made? When the enzyme is made it folds to form areas on the surface called active sites
Define Substrate The substance the enzyme reacts with/ works on.
Product Substance formed after the enzyme has worked on the substrate
Active site Area on the surface of an enzyme.
Specificity - enzymes One particular enzyme reacts with one particular substrate
Specificity- substrate The shape of the substrate must complement the shape of the active site on the enzyme
Specificity - active site Only complementary substrates fit in or attach to the specific shape of the active site.
Catabolic enzymes Catabolic enzymes speed up catabolic reactions
Anabolic enzymes Speed up anabolic reactions
Example of catabolic enzymes Amylase converts starch to maltose
Example of anabolic enzymes DNA polymerase forms and repairs DNA
Inhibitors Substances that prevent enzymes from working
Example of an inhibitor Antibiotics (penicillin) Aspirin
Main factors that affect enzyme activity 1. Temperature 2. pH 3. Enzyme concentration 4. Substrate concentration 5. Presence if inhibitors

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.
