TermDefinition
Molecule The smallest unit of a compound that still maintains the properties of that compound.
Compound two or more atoms chemically combined
Equilibrium a state in which a molecule is evenly spread out
Endocytosis he active transport of large molecules through the cell membrane. The membrane surrounds the material and forms a package that enters the cell.
Atomic Number The number of protons in the nucleus of the atom
Protein compounds made up of amino acids that are used to build cell parts and control chemical reactions in the body
Element a specific type of atom with a certain number of subatomic particles and specific properties
Facilitated Diffusion The diffusion of glucose by a way of carrier proteins in the cell membrane (moving glucose)
Neutron a subatomic particle with no charge
Atom the building block of matter
Organic Compound Any compound with hydrogen and carbon
Carbohydrate compound that is a primary source of energy
Electron A subatomic particle with negative charge
Inorganic Compound any compound that does not contain carbon
Active Transport the movement of materials that requires cell to use energy
Proton subatomic particle with a positive charge
Selective Permeability/ Semipermeable The membrane that allows some things but not all things do
Atomic Mass The number of protons and neutrons in an atom
Exocytosis The movement of large molecules out of the cell. The Golgi bodies package proteins that are removed from the cell by this process.
Lipids compounds that break down to store large amounts of energy
Passive Transport The movement of molecules that does not require the cell to use its own energy
Osmosis the diffusion of water
Diffusion when molecules go from a higher concentration to a lower concentartion
Enzyme protein that speeds up chemical reactions in the body
Nucleic Acids compounds that store information
Monosaccharide one sugar (carbohydrate)
Disaccharide two sugars (carbohydrate)
Polysaccharide three or more sugars (carbohydrate)
Amino Acid base unit; amnio acid chain- polypeptide
Peptide one protein
dipeptide two protiens
polypeptide three or more proteins
DNA deoxyribonucleic acid original blueprint
RNA Ribonucleic acid; copy of blueprint
hydrolysis adding water to break down a compound
hypertonic causes the water to leave the cell
hypotonic (hippo) causes the water to enter the cell
isotonic causes the water and the solution to be equilibrium; no net movement
dehydration synthesis take out water to build
maltose glucose+glucose
sucrose glucose+fructose
lactose glucose+galactose

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.
