Cell Metabolism


What is Cell Metabolism? the sum of All Chemical Reactions in a cell
What determines Reation Direction/Law of Mass Action? INCREASES in Reactant --> INCREASES in Product formation
What are some of the determinants of Reaction Rates? 1. Chemical Concentrations of Reactants; 2. Temperature; 3. Activation Energy; 4. Catalysts
How does Heat determine Reaction Rates? 1. provides high impact collisions need to impart Activation Energy
What is Activation Energy? Kinetic Enregy NECESSARY to start a Chemical Reaction
What is the function of Catalysts? SPEEDS up Reaction, but is not consumed
Whata re Enzymes? metabolic Catalysts
What are the functions of Enzymes? 1. SPEED Reactions w/o being altered themselves; 2. DON"T CAUSE Reactions that would otherwise occur
What is a Substrate? Reactant: any Organic Molecule BOUND To or ACTED on by an Enzyme
What is an Enzyme? 3-Dimensional Protein Catalyst
What is an ES-Complex? Substrate ADSORBED onto the surface of Enzyme, forming TEMPORARY Chemical Association
What is Geometric Specificity? one Enzyme reacts with only Specific Substrates
What is an Active Site? area of an Enzyme molecule that fits the Geometric Configuration of a Specific Substrate
What is the basic scheme of Metabolic Reactions? Enzyme + Substrate --> <-- ES-Complex --> <-- Products + Enzyme
What is the fuction of Enzyme Action? LOWERS Activation Energy requirements
How does Enzyme Action LOWER Activation Energy? 1. WEAKENS/distorts existing bonds within a substrate or changes its shape; 2. promtes new bonds by properly ORIENTING 2 Substrates

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.
