Are enzymes carbohydrates or lipids or proteins?
The great majority of enzymes are proteins.Proteins are well suited to the job of catalysis, as they can fold into specific three-dimensional shapes that complement the shapes of their substrates.A few enzymes are RNA. For example, the activity of ribosomes depends in part on the catalytic activity of ribosomal RNA (rRNA).
Why is catalytic activity of enzymes essential to ensure and regulate cellular metabolism?
Enzymes lower the activation energy for chemical reactions, allowing the reactions to proceed. Enzymes also can serve to bring components of a reaction together in the proper orientation. Enzymes can hydrolyze macromolecules into smaller components, enabling them to be transported across the cell membrane. Without enzymes, many metabolic reactions would not be able to be conducted efficiently, if at all.
Can RNAs be enzymes?
RNA molecules that act as enzymes are called ribozymes(also called RNA enzymes or catalytic RNA).They have a well defined tertiary structure (like proteins), their activity is often coordinated to metal ions as cofactors, and they have been found to catalyze reactions in which a ribosome removes the amino group from an amino acid.
What effect does cooking have on enzyme activity?
You mean heating the enzymes? heating to a certain degree increases their rate of catalytic activity, until about 30-40 degrees Celsius. However if you continue heating, the enzyme's basic structure will be deformed (it changes shape), and since structure is essential to function, the enzymes activity will be reduced. that happens around 60-70 degrees Celsius, but it is different in various organisms.
What is the stabilization of an enzyme?
Immobilization of enzymes refers to enzymes that are localized in a defined space or physically confined in a distinct phase. It can be defined as restrictive localization of enzymes. The enzymes keep their catalytic activities.
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 are molecules that catalyze chemical reactions?
Enzymes

What are some differences and or similarities in the type of inhibition caused by heat acid or base and heavy metal ions on enzyme activity?
all inhibitors prevent the active site from binding to a substrate and causes enzymes to lose catalytic activity
What is the function of coenzymes?
Molecules required for the catalytic function of enzymes
What is the most important information about Enzymes?
They perform catalytic mechanisms.
What is a substance that slow or stop enzymes catalytic action?
inhibitors

Is methanol and pyridine can be used with enzymes without losing their activity?
what i know is enzymes are denatured in organic solvents loosing their activity.
