Metabolism

QuestionAnswer
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.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
