All recently named enzymes have names that end with the suffix - . |
|
|
5 | |
is the general name for an enzyme that removes hydrogen atoms from their substrates. |
|
|
6 | |
An is a different model of the same enzyme, catalyzing the same reaction, yet can be distinguished form other models usually by slight changes in chemical structure. |
|
|
7 | |
At temperatures above 37°C enzyme catalyzed reaction rates begin to slow down due to the fact that the structure of enzymes becomes altered at higher temperature. |
|
|
8 | |
Each enzyme characteristically has its peak activity in a very narrow pH range, known as the pH for that enzyme. |
|
|
9 | |
are ions needed for the activity of specific enzymes. |
|
|
10 | |
are organic molecules derived form niacin, riboflavin, and other water-soluble vitamins that are needed for optimal enzyme activity. |
|
|

|
|
12 | |
Along a metabolic pathway, many are formed which in turn become the substrates for further enzymatic reactions. |
|
|
13 | |
The mechanism by which a final product inhibits an earlier enzymatic step in its pathway is known as inhibition. |
|
|
14 | |
is an inherited defect in the enzyme that catalyzes the formation of the pigment melanin. |

|
|
18 | |
reactions release energy as they convert molecules with more free energy to molecules with less free energy (more entropy). |
