Anatomy and Physiology 1 Chemical Bonding and Reactions

QuestionAnswer
Electron Shell a layer of electrons that encircle the nucleus at a distinct energy level
Valence Shell The outermost shell in any atom which contains electrons
Valence shells are stabilized when they are closed identify how many electrons are needed in order for the first shell to closed? 2
Valence shells are stabilized when they are closed identify how many electrons are needed in order for the second shell to closed? 8
Valence shells are stabilized when they are closed identify how many electrons are needed in order for the third shell to closed? 8
Molecule two or more atoms covalently bonded together
Ion electrically charged particle with an overall negative or positive charge
Cation positively charged particle
Anion negatively charged particle
One important fact you should know about electrical charges Opposites attract / Sames repel
How is an ion formed when an atom donates an electron and another atom receives it
ionic bond the attraction between two oppositely charged atoms
Covalent Bond the attraction between two atoms resulting from sharing valence electrons which ends in the result of molecules
Polar Covalent Bond Covalent bond that forms as a result of unequal sharing of valence electrons
Nonpolar Covalent Bond Covalent bond that forms as a result of equal valence electron sharing
Hydrogen Bonds are individually ________ and __________. Weak, transient
Hydrogen Bonds attraction between hydrogen containing polar molecules (an intermolecular force)
Chemical Reaction Processes in which chemical bonds are broken and/or formed as starting substances is/are converted into ending substances
Reactants starting substnaces
Products ending substances
decomposition reaction a larger number of smaller product molecules are generated from a smaller number of larger reactant molecules
Synthesis Reaction a smaller number of larger product molecules are generated from a larger number of smaller reactant molecules
Catabolic Reaction/ Catabolism decomposition reaction
Anabolic Reaction/ anabolism synthesis reactions occurring in cells
hydrolysis Reaction decomposition reaction when cells consume Water
dehydration Reaction when water is removed during the synthesis reaction
Exchange reaction atoms or groups of atoms are swapped between molecules
Define Reversible in terms of chemical equilibrium a chemical reaction is said to be reversible when the products of a reaction can be converted back into the original reactants
Chemical Equilibrium when two reactions occur at the same rate
Redox Reaction energy in the form of electrons is transferred from the substance that is oxidized to the substance that is reduced
Activation Energy The "threshold" level of energy needed to break bonds in the reactants
Endergonic chemical reactions that absorb more energy than they release
Exergonic chemical reactions that release more energy than they absorb
Catalyst a substance that increase the rate of chemical reaction without itself undergoing any change
Receptor sensitive to change or detects the change in the variable
Control Center sent a chemical signal by the receptor which then in turn sends a signal to the effector organ
Effector affects the variable by sending a signal to alter said variable by some type of action
Negative Feedback involves reversing the stimulus; the response should then be the opposite of the stimulus
Set-Point the value about which a physiological variable in maintained homeostatically

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.
