Cofactors

about 2/3 of human enzymes require a nonprotein cofactor

2

Coenzymes

Organic cofactors derived from water soluble vitamins (niacin, riboflavin)

3

Three components of nucleotides

-Nitrogenous base
-Sugar
-phosphate groups

4

ATP-best known nucleotide

-Adenine
-Ribose
-Phosphate groups

5

Adenosine triphosphate

-Bodys most important energy-transfer
-Briefly stores energy gained from exergonic reactions
-releases it within second for physiological work

6

Nucleic Acids

DNA(deoxyribonucleic acid)
RNA(ribonucleic acid)

7

DNA(deoxyribonucleic acid)

-pentose sugar(deoxyribose)
-phosphate group
-nitrogenous base
-cytosine, thymine, guanine or adenine

8

RNA(ribonucleic acid)

-pentose sugar(ribose)
-phosphate group
-nitrogenous base
-Adenine, uracil, guanine or cytosine
-3 types(messenger, ribosomal, transfer)
