QuestionAnswer
Enzyme Biological catalyst made of amino acids.
Substrate Reactant an enzyme catalyzes
Active Site structure on the enzyme
Reactants The molecules needed for a chemical reaction to occur
Products Molecules that are made when a chemical reaction is over
Activation Energy The amount of energy needed for a reaction to occur.
Heat of Reaction The difference in energy between the reactants and products of a chemical reaction
catalyst A substance that speeds up a chemical reaction without being "used up" in the reaction.
coenzymes Metal ions or organic compounds that help enzymes.
inhibitors Substances that block an enzyme's activity.
competitive inhibitor An inhibitor that takes the place of a substrate in the active site.
non-competitive inhibitor An inhibitor that alters an enzyme's function by changing its shape.
chemical reaction A process that changes one set of chemicals into another set of chemicals
spontaneous reaction Term used to describe a reaction that will occur without additional energy
reactant Element or compound that enters into a chemical reaction.
product A chemical substance formed as a result of a chemical reaction.
lock and key Model of enzyme activity that explains how a particular enzyme will only fit with one particular type of substrate.
hydrolysis Breaking down complex molecules by the chemical addition of water.
denature A change in the shape of a protein (such as an enzyme) that can be caused by changes in temperature or pH (among other things).
law of conservation of mass States that atoms are neither created nor destroyed in a chemical reaction.
Iodine A solution that can be used as a starch indicator. Turns from amber color to dark purple/black in the presence of starch.
Bile Produced by the liver to mechanically increase the surface area of fat by breaking it into small droplets

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.
