|
|
||||
|---|---|---|---|---|---|
| Passive Transport | movement across the cell membrane that does not require energy from the cell
🗑
|
||||
| Concentration Gradient | A difference in the concentration of a substance across a space
🗑
|
||||
| Equilibrium | A condition in which the concentration of a substance is equal across a space
🗑
|
||||
| Diffusion | The movement of substance from an area of high concentration caused by the random motion of particles of the substance
🗑
|
||||
| Osmosis | the diffusion of water through a selectively permeable substance
🗑
|
||||
| Hypertonic | when water diffuses out of the cell, and causes the cell to shrink
🗑
|
||||
| Hypotonic | water move in, it causes the cell to swell because of osmosis
🗑
|
||||
| Isotonic | No net water movement, a solution that produces no change in cell volume because of osmosis (cytoplasm) and the fluid outside the cell have the same concentration of free water molecules
🗑
|
||||
| Covalent Bonds | Sharing of electrons
🗑
|
||||
| Hydrogen Bonds | an negative molecule connects to a postive molecule, creating a partially charged molecule
🗑
|
||||
| Ionic Bonds | a stealing of electrons
🗑
|
||||
| Non-polar covalent | an equal sharing of electrons
🗑
|
||||
| Polar Covalent | non-equal sharing of electrons
🗑
|
||||
| Name the Four life molecules | Lipids, Carbohydrates, Proteins, and Nucleic Acids
🗑
|
||||
| Hydrocarbon | long strands of carbon and hydrogen surrounding it
🗑
|
||||
| Metabolism | I eat, I break it down, I use it (energy)
🗑
|
||||
| Carbohydrates | Carbon, Hydrogen, and oxygen 1:2:1 ratio
🗑
|
||||
| Complex carbohydrates | cellulose, starch and glycogen
🗑
|
||||
| Lipids | Major energy storer used in cell membrane men and women store it differently
🗑
|
||||
| Protein | Copy dan, they contain nitrogen, made of amino acids, held together by peptide bonds, Sub groups: enzymes, antibodies, and protein hormones
🗑
|
||||
| Nucleic Acids | Dna, Rna, nucleotides
🗑
|
||||
| Active Transport | diffusion from low to high concentration using energy
🗑

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.
