Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions, Coenzymes are small organic molecules that transport chemical group. Inhibitors are activators or molecules that increase or decrease enzyme activity. Apoenzyme is a protein component of an enzyme, to which the coenzyme attaches to form an active enzyme where as holoenzyme is an active, complex enzyme consisting of an apoenzyme and a coenzyme.

How are apoenzyme and coenzyme and holoenzyme and confactor related?
Holoenzyme= Apoenzyme+ coenzyme
A holoenzyme is composed of an apoenzyme and a what?
Coenzyme
What is the component of holoenzyme?
is a combination of a protein called a apoenzyme and one or more cofactors
What is the difference between a coenzyme and an apoenzyme?
A coenzyme is a non-protein organic molecule that is required for the activity of an enzyme, while an apoenzyme is the protein component of an enzyme without its cofactor or coenzyme. Together, a coenzyme and an apoenzyme form a holoenzyme that is fully functional.
Protein part of holoenzyme is called?
DNA does N O T have proteine or parts of protein in its molecule.It consists of a 'ribose' part, a 'phophate' part and a 'nucleic acids' part.
What is a co substrate?
A co-substrate is a co-factor that transforms an apoenzyme into a holoenzyme. However, it is not tightly bound to the protein and freely binds and releases (but is not chemically altered). This is different from a tightly bound cofactor such as heme in hemeglobin, these are termed prosthetic groups.
What is apoenzyme?
An apoenzyme is an inactive haloenzyme lacking a cofactor.
What is The protein portion of an enzyme that is lacking a cofactor is called?
an apoenzyme
What is Difference between holoenzyme and core enzyme?
Core enzyme (without σ) does not specifically bind promoters, but rather dsDNA very tightly • KD ≈ 5 x 10-12M t1/2 ≈ 60 minutes • Holoenzyme binds non-promoter DNA more loosely • KD ≈ 10-7M t1/2 > 1 sec
Type of protein that is a catalyst?
apoenzyme
Is ethanol a holoenzyme?
No,you idiot. Ethanol is a hydrocarbon compound.
Will an apoenzyme that looses its coenzyme subunit will be non-functional?
Yes, without its coenzyme subunit, the apoenzyme will not be able to carry out its function. The coenzyme is essential for the proper functioning and activity of the enzyme. Without it, the apoenzyme will lack the necessary cofactor to catalyze the reaction efficiently or at all.
