Enzymes

QuestionAnswer
What is an enzyme made out of? Proteins.
What are enzymes? Substances that speed up chemical reactions.
Enxymes can also be known as _____. Catalysts.
To decrease the energy thats needed for a chemical reaction enzymes _______. Catalyze the chemical reactions.
What would happen if enzymes didn't exist? Some chemical reactions would not perform fast enough to support life.
Because enzymes are proteins they are made in the cell's ______. Ribosomes.
The substances that enzymes act on are called _____. Substrates.
Enzymes are very _____ on the substrates that they catalyze. Specific.
How can you tell if you are talking about the name of an enzyme? Suffix -ase.
An enzyme _____ a substrate or catalyzes it. Breaks down.
Catalase, polymerase, and lactase are all examples of _____. Enzymes.
Why are enzymes important? Because they perform all types of jobs that help an organism survive by catalyzing reactions.
What is the shape of an enzyme? Enzymes each have a specific shape because they work on different parts of the body.
The surface of an enzyme that has a lot of folds makes holes or ___. Pockets.
What are active sites? The pockets on an enzyme.
What happens on the active site? The enzyme breaks down or catalyzes the substrate.
The active site is where the enzyme's folds ___ the substrate's folds. Fit.
Why are enzymes and substrates like puzzle pieces? Because they have a specific spot where they match together, and the enzyme breaks down the substrate.
What would happen if the shape of the enzyme didn't match with the substrate? The enzyme wouldn't be able to function and break down the subtrate during the reaction.
What example can be used to describe how an enzyme and a substrate fit together? Lock-and-key.
When an enzyme catalyzes a substrate which of the two breaks? The substrate breaks down.
How many times can an enzyme catalyze chemical reactions? Enzymes can be used over and over again and keep functioning with no problem.
What happens after an enzyme catalyzes a substrate? It leaves it and continues to find another substrate to catalyze.
What two things can affect the shape of an enzyme? Temperature and pH.
If the temperature and pH changes where an enzyme is working, what will happen to the enzyme? The rate at which the enzyme works will decrease or maybe the enzyme will stop working.

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.
