BIO CH 6: Metabolism: Energy and Enzymes
|Active Site|| |
Small part of enzyme fits with substrate/s (site undergoes small change in shape)
|ADP (adenosine diphosphate)||Factors in producing ATP|
|ATP (adenosine triphosphate)||Common energy currency of cells|
|Coupled Reactions||Occur in the same place, same time, in a way that an energy-releasing (exergonic) reaction drives an energy requiring (endergonic) reaction|
|Enzyme||Protein that functions as an organic catalyst to speed a chemical reaction w/o being affected by the reaction|
|Enzyme inhibition||When a molecule (the inhibitor) binds to an enzyme and decreases its activity|
|1st Law of Thermodynamics||(Law of conservation of energy) Energy cannot be created/destroyed, but it can be changed from one form to another|
|2nd Law of Thermodynamics||Energy cannot be changed from one form to another w/o a loss of usable energy|
|Metabolism||Sum of all the chemical reactions that occur in a cell|
