||||
|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
