Figure 1-1: A flow chart of the two types of cofactors. Apoenzyme-An enzyme that requires a cofactor but does not have one bound. An apoenzyme is an inactive enzyme, activation of the enzyme occurs upon binding of an organic or inorganic cofactor. Holoenzyme-An apoenzyme together with its cofactor. A holoenzyme is complete and catalytically active. Most cofactors are not covalently bound but instead are tightly bound. However, organic prosthetic groups such as an iron ion or a vitamin can be covalently bound.
Adenosine triphosphate (ATP) is a nucleotide that consists of an adenosine and a ribose linked to three sequential phosphoryl (-PO32-) groups via a phosphoester bond and two phosphoanhydride bonds.ATP is the most abundant nucleotide in the cell and the primary cellular energy currency in all life forms.TP consists of adenosine and is composed of an adenine ring, ribose sugar, and three phosphate groups (triphosphate). The groups of the phosphate group are usually called as the alpha (Î±), beta (Î²), and gamma (Î³) phosphates.
