|---|---|---|---|---|---|
| ATP | Adenosine Tri Phosphate: Energy currency of cell Fully charged energy
🗑
|
||||
| ADP | Adenosine Di Phosphate - Discharged energy molecule
🗑
|
||||
| First Law of Thermodynamics | Energy cannot be created or destroyed; it can be transformed and transferred from one form to another.
🗑
|
||||
| Second Law of Thermodynamics | Energy conversion is inefficient and energy lost as heat disperses and lost.
🗑
|
||||
| Entropy | Measure of energy lost as heat .
🗑
|
||||
| Potential Energy | Energy Available to do work
🗑
|
||||
| Kinetic Energy | Energy at Work
🗑
|
||||
| Anabolic Reaction | Reactions that forms a bond; make a new molecule
🗑
|
||||
| Catabolic Reaction | Reactions that breaks a bond; breaks a molecule
🗑
|
||||
| Endergonic Reaction | Reactions that requires energy - anabolic reactions
🗑
|
||||
| Exergonic Reactions | Reaction that releases energy - Catabolic reactions
🗑
|
||||
| Metabolism | Sum total of all reactions in a body
🗑
|
||||
| Energy | Capacity to do work
🗑
|
||||
| Enzyme | Protein molecule that catalyzes a reaction and make it happen faster.
🗑
|
||||
| Activation Energy | Energy needed to start a reaction
🗑
|
||||
| Substrate | Molecules that take part in a reaction ( associated with enzyme)
🗑
|
||||
| Active Site | Region on an enzyme that binds to the substrate
🗑
|
||||
| Competititve Inhibition | Inhibitor binds to the active site and prevents the enzyme from catalyzing the reaction
🗑
|
||||
| Non-competitive inhibition | Inhibitor changes the active site of the enzyme making it unavailable to catalyze the reaction
🗑
|
||||
| Oxidation reaction | Reaction where a reactant loses electron .
🗑
|
||||
| Reduction Reaction | REaction where a reactant gains an electron.
🗑
|
||||
| Redox Reaction | Coupled reaction where one reactant loses electron and another gains an electron.
🗑
|
||||
| Isotonic Solution | Solute concentration is the same inside and outside of membrane
🗑
|
||||
| Hypertonic Solution | Solute concentration is high in the solution compared to the solute concentration in the cell - water will move out of the cell.
🗑
|
||||
| Hypotonic Solution | Solute Concentration is low in the solution compared to the solute concentration in the cell - water will move in to the cell
🗑
|
||||
| Passive transport | No energy required to move particles across a membrane , movement happens along with the concentration gradient high -. Low
🗑
|
||||
| Active Transport | Energy required to move particles across membrane; movement happens against the concentration gradient -low-> High
🗑
|
||||
| Phagocytosis | Vesicles moving into the cell with large solid substance - cell eating.
🗑
|
||||
| Pinocytosis | Vesicles moving into the cell with fluids - cell drinking
🗑
|
||||
| Exocytosis | Movement of Vesicle out of cell
🗑
|
||||
| Endocytosis | Movement of Vesicle into the cell
🗑

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.
