|---|---|---|---|---|---|
| Active Transport | Moves solutes against their concentration gradient.
🗑
|
||||
| Primary Active Transport | Required energy comes directly from ATP hydrolysis.
🗑
|
||||
| Secondary Active Transport | Required energy is obtained indirectly from iconic gradients created by primary active transport.
Energy stored in gradients is used indirectly to drive transport of other solutes.
🗑
|
||||
| Vesicular Transport | Involves a large particles, macromolecules and fluids cross membrane in membranous sacs called Vesicles.
🗑
|
||||
| Endocytosis | Transport into cell
🗑
|
||||
| Exocytosis | Transport out of cell
🗑
|
||||
| Phagocytosis | type of endocytosis that is referred to as cell eating.
🗑
|
||||
| Pinocytosis | type of endocytosis that is referred to as cell drinking or fluid phase endocytosis.
🗑
|
||||
| Receptor Mediated Endocytosis | involves endocytosis and transcytosis of specific molecules.
🗑
|
||||
| Secretory Vesicle | Substance being ejected is enclosed in this
🗑
|
||||
| Resting Membrane Potential | Electrical potential energy produced by separation of oppositely charged particles across plasma membrane in all cells.
Maintained by through action of the Na+-K+ pump, which continuously ejects 3Na+ out of cell and brings 2K+ back inside.
🗑
|
||||
| Cell Adhesion Molecules | every cell has thousands of sticky glycoprotein CAM's projection from membrane.
🗑
|
||||
| Plasma Membrane Receptors | Membranes receptor proteins serve as binding sites for several chemical signals.
🗑
|
||||
| Contact Signaling | Cells that touch recognize each other by each cells unique surface membrane receptors.
🗑
|
||||
| Chemical Signaling | Interaction between receptors and ligands that cause changes in cellular activities. Activated G protein.
🗑

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.
