Misc.
I feel inhibited (or stimulated)
But I need help
Is energy really free?
100

A substance that speeds up a reaction but is not consumed during the reaction

What is a catalyst?
100

When there is more substrate available than can be processed, the rate of the reaction is at this. 

What is Vmax ? (maximum velocity). 

100

A molecule that binds the active site and prevents the substrate from entering

What is a competitive inhibitor?

100

A non-protein molecule that is needed for an enzymatic reaction to occur

What is a cofactor? (sometimes "coenzyme," though more properly a "co-substrate). 

100

Processes that break complex molecules in to simpler molecules with lower chemical PE.

What is catabolism (or a catabolic process)?

200

While almost all enzymes are proteins, a few very important ones are made of this

What is RNA

200

The concentration of substrate that yields ½ of the maximum rate

What is the Km?

200

A molecule that binds to an enzyme somewhere other than the active site and slows down the reaction

What is a non-competitive inhibitor?

200

Many cofactors needed by enzymes are known as these

What are vitamins?

200

A process that build more complex, higher-energy molecules out of simpler ones.

What is anabolism (or anabolic processes)?

300

The "reactant" in a reaction involving an enzyme

What is the substrate?

300

Energy will distribute evenly in the space available to it-OR-for any spontaneous process, the entropy of the universe will increase

What is the second law of thermodynamics

300

A protein or other molecule binds an enzyme away from the active site and activates it.

What is allosteric activation

300

A series of catalytic steps, each catalyzed by different enzymes, that result in the production of an important product

What is a metabolic pathway?

300

Energy needed to initiate a reaction

What is activation energy?

400

The place on an enzyme where the substrate binds

What is the active site?
400

Many cofactors are derivatives of the building blocks of this macromolecule

What is RNA

400

When a reaction is spontaneous, this value is negative.

What is 

\DeltaG^0?

500

Catalysts work by lowering this

What is the Activation Energy?

500
When a product of a multi-step pathway inhibits an earlier step in the pathway

What is feedback inhibition? 

500

A negatively charge functional group that, when added to a protein, can change its shape and function (usually activate it). 

What is a phosphate

500
Energy available to do work when a reaction occurs 

What is free energy?
