TermDefinition
metabolism sum of all chemical reactions in the body
catabolic reaction complex molecule is broken down into simpler ones with the release of energy
anabolic reaction convert smaller particles into more complex ones requiring energy
enzyme organic, chemical, metabolic, biological, catalyst that speeds up or slows down the rate of reaction w/o being used up in the reaction itself
catalyst a substance that speeds up a reaction w/o being used up in the reaction itself
shape of enzyme globular (highly folded)

product is the substance(s) the enzyme forms
factors that effect enzyme activity temp and ph
denatured enzyme an enzyme that has lost its shape and cannot carry out its function anymore
optimum what is works best at

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.
