QuestionAnswer
NADH An electron carrier, donates electrons in cellular processes
NAD+ An electron carrier, accepts electrons in cellular processes
FADH2 An electron carrier,donates electrons in cellular processes
FAD+ an electron carrier, accepts electrons in cellular processes
active transport the movement of substances through a membrane against a concentration gradient using membrane-bound carrier proteins and energy from ATP
sodium-potassium pump an active-transport mechanism that pumps sodium and potassium ions into and out of a cell
aerobic cellular respiration The set of reactions that takes place in the cell in the presence of oxygen and releases energy stored in glucose
anaerobic cellular respiration the set of reactions that takes place in the cell in the absence of oxygen and releases energy stored in glucose
glycolysis a process for harnessing energy in which a glucose molecule is broken into two pyruvate molecules in the cytoplasm of a cell
mitochondrion a eukaryotic cell organelle in which aerobic cellular respiration occurs
mitochondrial matrix the fluid that fills the interior space of the mitochondrion
intermembrane space the fluid-filled space between the inner and outer mitochondrial membranes
krebs cycle a cyclic series of reactions that transfers energy from organic molecules to ATP,NADH, and FADH2,and removes carbon atoms as CO2
oxidative ATP synthesis the production of ATP from a series of oxidation reactions
alcohol fermentation a form of fermentation occurring in yeast in which NADH passes its hydrogen atoms to acetaldehyde,generating carbon dioxide,ethanol, and NAD+
lactic acid fermentation a form of fermentation occurring in animal cells in which NADH transfers its hydrogen atoms to pyruvate,regenerating NAD+ and Lactic Acid
lactic acid threshold the value of exercise intensity at which lactic acid production increases

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.
