Module 10 Set 6

QuestionAnswer
apoenzyme protein component of an enzyme
cofactor nonprotein component of an enzyme
prosthetic group firmly attached
coenzyme loosely attached
holoenzyme apoenzyme + cofactor
a typical exergonic reaction A + B → ABt → C + D
transition-state complex resembles both the substrates and the products
enzyme speeds up reaction by lowering Ea
activation energy energy required to form transition-state complex
lock-and-key model: only the substrate (key) fits into the active site (key hole) of the enzyme (lock)
induced-fit model: only the proper substrate is capable of inducing the proper alignment of the active site for the enzyme to perform its catalytic function
how enzymes lower Ea: By increasing concentrations of substrates at active site of enzyme
how enzymes lower Ea: By orienting substrates properly with respect to each other in order to form the transition-state complex
isoenzymes different enzymes that catalyze same reaction
each end product regulates the initial pacemaker enzyme
each end product regulates its own branch of the pathway
feedback inhibition also called end product inhibition
inhibition of one or more critical enzymes in a pathway regulates entire pathway
pacemaker enzyme catalyzes the slowest or rate-limiting reaction in the pathway

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.
