|---|---|---|---|---|---|
| Metabolism | The sum of all chemical transformations taking place in a cell. The overall process by which living systems acquire and utilize energy. The overall network of enzyme catalyzed reaction pathways.
🗑
|
||||
| Metabolic Pathways | Linear Pathway: glycolysis
Branched Pathway: amino acid biosynthesis
Cyclic Pathway: citric acid cycle.
🗑
|
||||
| Network Nature of Metabolism | Initial reactants vs. intermediates vs. final products.
🗑
|
||||
| Metabolic Pathways | Linear Pathway: glycolysis
Branched Pathway: amino acid biosynthesis
Cyclic Pathway: citric acid cycle
🗑
|
||||
| Anabolism | build large molecules, require ATP, divergent pathways
🗑
|
||||
| Pharmacy relevance | Must be spontaneous: thermodynamically favorable, negative delta G
🗑
|
||||
| Oxidizing Agent | removes electrons from another reactant in a redox reaction. the oxidizing agent is reduced.
🗑
|
||||
| Redox Reactions | An oxidizing agent (also called an oxidant, oxidizer or oxidiser) can be defined as a substance that removes electrons from another reactant in a redox chemical reaction. The oxidizing agent is reduced. Having electrons taken away.
🗑
|
||||
| delta G prime | standard free energy when all components = 1.0M at pH7, 25C 1 atm.
🗑
|
||||
| delta G | actual free energy change under cellular conditions.
🗑
|
||||
| Free energy changes during chemical reactions | negative delta G: spontaneous
positive delta G: need coupled reactions, Hess' Law
zero delta G: Lechatelier's Principle.
🗑
|
||||
| large Keq | spontaneous, large -deltaG or very negative delta G.
🗑
|
||||
| phosphoryl group transfer details | special role of ATP as the energy currency that links catabolism and anabolism. use ATP to drive: anabolism, mechanical motion, & active transport.
🗑
|
||||
| Reverse Reactions | Same absolute value just change the sign.
🗑
|
||||
| Importance of ATP intermediate phosphoryl transfer potential | It is in the middle and may drive other reactions.
🗑
|
||||
| Regulation of metabolic pathways | catabolic pathways are only activated when it is needed.
🗑
|
||||
| phosphocreatine during exercise | 100m sprint fast-twitch muscle uses phosphocreatine to generate ATP.
marathon- slow-twitch muscle uses slow and steady process of nutrient catabolism/oxidative phosphorylation(mitochondria)
🗑

||||
| Fats | Most Energy; fatty acids.
🗑

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.
