|---|---|---|---|---|---|
| Energy | Energy is the capacity to do work, either actively( kinetic energy) or stored for later use (potential energy). energy is transferred with electrons. Oxidation is the loss of electron. Reduction is the gain of one.
🗑
|
||||
| exergonic | an energy yielding process; this can be exothermic ( a heat yielding process) or exophotic (a light yielding process)
🗑
|
||||
| endergonic | an energy requiring process; this can be endothermic (a heat yielding process) or endophotic (a light requiring process)
🗑
|
||||
| entropy | a measure of randomness in a system; it takes energy input to maintain a complex organized system (hence why you "decay" when you die and no longer have energy to maintain your organized state).
🗑
|
||||
| free energy | energy which is available to do work( that is, what you want to do) because it is not already in some designated form, such as heat or light.
🗑
|
||||
| Gibbs free energy exchange | the change in heat content minus the change in entropy multiplies by the absolute temperature
🗑
|
||||
| oxidation | loss of electron; electron is moved to a lower energy level and therefore energy is released during oxidation; does not always involve oxygen
🗑
|
||||
| reduction | gain of an electron; electron is moved to higher energy level and this requires an input of energy; this energy is stored, so a molecule or compound like methane is full of potential energy.
🗑
|
||||
| metabolism | the sum of all energy exchanges that occur through chemical reactions in a living cell; equal to anabolism+catabolism
🗑
|
||||
| anabolism | all chemical reactions involved in biosynthesis
🗑
|
||||
| catabolism | all chemical reactions involved in the degeneration of larger molecules
🗑
|
||||
| enzymes | global water soluble proteins which lower the activation energy of chemical reactions in living cells, thereby speeding up the chemical reaction; act as a catalyst b facilitating reaction without being altered, can be reused as needed.
🗑
|
||||
| cofactors | most enzymes require additional substances called cofactors in order to function properly; cofactors are divided into inorganic ions and organic coenzymes. Cofactors can change the shape of enzymes to help them fit and process there substrate.
🗑
|
||||
| Phosphorylation | the process of making ATP
🗑
|
||||
| photophosphorylation | The use of light to make ATP
🗑
|
||||
| oxidative phosphorylation | the use of oxygen to make ATP.
🗑

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.
