BIO QUIZ

QuestionAnswer
Energy capacity to cause change( in KE and PE)
Kinetic Energy Energy of motion
Thermal energy type of KE with random movement of atoms or molecules (passing from one object to another is HEAT)
Potential energy energy matter posses bc of its location or structure
Chemical energy potential energy available for release in a chemical reaction
thermodynamics study of energy transformations
1st (law of energy conservation) energy is constant, cannot be created or destroyed, just transferred
Cellular resoiration Chemical energy stored in organic molecules is used to produce atp (O2 is broken down to CO2 and H2O to release ATP)
entropy measure of disorder or randomness
second law every energy conversion increases the entropy
exergonic reaction releases energy
endergonic require net input of energymand stop products rich in PE (energy inward)
Metabolism total of an organisms chemical reactions
Metabolic pathway chemical reactions that builds or breaks down a complex molecule
energy coupling use of energy from an exergonic reaction to drive an endergonic reaction
atp powers nearly all forms of cellular work
phosphorylation transfer of phosphate group from atp to another molecule
kilocalories measure the quantity of heat
redox reaction transfer of one electrons from one molecule to another
oxidation loss of electrons from one substance
reduction addition of electrons to a substance

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.
