1 | | As a general rule, all enzymes are composed of molecules. |
|
|
2 | | That particular part of an enzyme that is active in catalyzing a reaction is the site. |
|
|
3 | | The (double hyphenated word) model describes how enzymes work to catalyze reactions. |
|
|
4 | | 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. |
|
|
11 | | The direction in which a reversible reaction proceeds is determined by the (4 words). |
|
|
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. |
|
|
15 | | Tay-Sachs disease and hypercholesteremia are inborn errors in the metabolism of molecules. |
|
|
16 | | Entropy describes the degree of of a system. |
|
|
17 | | Since input of the sun's energy is required, the chemical reactions in the process of photosynthesis are . |
|
|
18 | | reactions release energy as they convert molecules with more free energy to molecules with less free energy (more entropy). |
|
|
19 | | Heat is measured in units called . |
|
|
20 | | The universal energy carrier that efficiently couples the energy released by the breakdown of food molecules to the energy required by the diverse endergonic processes in the cell is . |
|
|
21 | | When electrons are lost from an atom or molecule, the atom or molecule is . |
|
|
22 | | and are two important coenzymes that are derived from water-soluble vitamins and serve to transfer hydrogen atoms (and their electrons) about the cell, providing energy. |
|
|
23 | | Reduction reactions are most often catalyzed by a class of enzymes known as . |
