Module 11 Set 1

QuestionAnswer
total of all chemical reactions occurring in cell metabolism
breakdown of larger, more complex molecules into smaller, simpler ones; energy is released and some is trapped and made available for work catabolism
synthesis of complex molecules from simpler ones with the input of energy anabolism
most respiration involves use of an electron transport chain
in _____, final electron acceptor is oxygen aerobic respiration
in _____, final electron acceptor is different exogenous acceptor such as NO3-, SO42-, CO2, Fe3+ or SeO4(2-); organic acceptors may also be used anaerobic respiration
as electrons pass through the electron transport chain to the final electron acceptor, a _________ is generated and used to synthesize ATP proton motive force
Use inorganic electron source, can be aerobic or anaerobic organism (mostly aerobic) Chemolithotroph
uses an endogenous electron acceptor fermentation
usually an intermediate of the pathway used to oxidize the organic energy source e.g., pyruvate endogenous electron acceptor
does NOT involve the use of an electron transport chain nor the generation of a proton motive force fermentation
in fermentation ATP is synthesized only by substrate-level phosphorylation
what stage of aerobic catabolism does large molecules (polymers)->small molecules (monomers) 1st stage
what stage of aerobic catabolism does initial oxidation and degradation to pyruvate 2nd stage
what stage of aerobic catabolism oxidation and degradation of pyruvate by the tricarboxylic acid cycle (TCA cycle) 3rd stage

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.
