What is a non-protein helper of an enzyme molecule called?
the general term is cofactor, but more specifically, if the cofactor is an organic molecule, it is called a coenzyme
What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
What is the purpose of GUAIACOL?
Guaicol is used as a substrate for peroxidase activity, when we treat it with enzyme the activity of enzyme increases at a higher rate.
What is the difference between coenzyme and prosthetic group?
CO-ENZYME: A dissociable cofactor, usually organic. PROSTHETIC GROUP: non-dissociable cofactor.
What is inhibition and why enzymes need to be inhibited?
- Inhibition of an enzyme is to inhibit the catalytic activity of the enzyme. - Because, by blocking or inhibiting an enzyme's activity can kill a pathogen or correct a metabolic imbalance. Example : Inhibition of HIV protease.
What is the Effect of mineral and vitamin deficiency on enzyme activity?
many vitamins and minerals play crucial roles in many metabolisms as coenzyme or cofactor. Deficiency of those lower the related-enzyme activity.
The basic function of a coenzyme?
A coenzyme helps an enzyme do its' work. Without the coenzyme, the enzyme will remain inactive.
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.
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.
Which organic molecule is sometimes required for certain enzyme activity called?
coenzymes
Is riboflavin an example of a coenzyme?
A coenzyme is a nonprotein compound that is loosely bound to an enzyme. In humans, the element copper is considered as a coenzyme.
What co-enzyme reduce without altering rate of reaction?
what coenzyme reduce without altering rate of reaction
Is acetyl coa an enzyme?
Not exactly. Acetyl CoA is a coenzyme and participates in the Kreb cycle. It is made from the mitochondria and not from ribosomes, nad usually is a vitamin or mineral.
What is the difference between apoenzyme and holoenzyme?
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.
What are coemzymes?
These are either a vitamin or mineral that works with an enzyme. The enzyme doesn't work without it (them).
What are two water-soluble vitamins in the bodyand what are their functions?
Vitamin C and all Vitamin Bs are water soluble. Vitamin C is ran important antioxidant and cofactor for enzyme activities. A form of Vitamin B1 is important as a coenzyme in the catabolism of amino acids and sugars.
Explain the effect of mineral and vitamin deficiency on enzyme activity?
many enzymes require vitamins and/or minerals to function properly. Without them, they cannot catalyze their reaction.
