Enzyme speeds up the chemical reaction. So, it would speed the cells for life and live.

Cells regulate enzyme activity through 2 methods; allosteric inhibition and competitive inhibition. Allosteric inhibition is when something (Ion, organic chemical, etc) bonds to a site on the enzyme ( not on the active site) and that changes the shape of an enzyme. Competitive inhibition is when something (ion, organic chemical, etc) enters the active site so that the true substrate cannot enter into the enzyme to have a reaction.
Metabolic enzymes are the most active for human cells. The reason for this is because they regulate each biochemical reaction.
Nuclease are enzymes in a cell that break apart RNA and DNA so that their parts can be recycled, and yes human cells contain these enzymes. If you meant nucleus, which is where the DNA resides in a (most) cells, then yes, most human cells contain a nucleus (the most notable exception being red blood cells).
Most of the metabolic activity in the cell occur in the cell's cytoplasm, specifically in the mitochondria in eukaryotic (not bacterial or archaeal) cells.
"Because their catalytic role renders most enzymes ineffective after their initial activity, a cell must produce large amounts of each enzyme in order to perform effectively." this is incorrect because 99+% of enymes are used until the cells dies because they are costly (in energy terms) to make.
They only store ATP for a few seconds of activity.
Many enzymes are affected by changes in temperature. Cells can regulate the activities of enzymes in many ways. Most cells contain proteins that help turn key enzymes "on" and "off" at critical stages in the life of the cell. Enzymes play essential roles in regulating chemical pathways, making materials that cells need, releasing energy, and transferring info. there ya go ppl....... always there to help ya know (:

Enzymes are beneficial to cells due to the functions that they perform. Most chemical reactions are catalyzed by enzymes in the cell.
cyclins regulate the timing of the cell cycle in eukaryotic cells,cancer cells do not respond to the signals that regulate the growth of most cells.
Cancer cells do not respond to the signals that regulate the growth of most cells. such cells called cancer cells divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues

They form cancers.
The lysosome contains the most enzymes of the cell. This is because the lysosome is the site of cellular digestion.
They are used to make tough meet tender to eat.The most common enzyme used is called "papain" (papaya proteinase I) and is derived from papaya and certain other plants.
Digestive enzymes are optimal around 37C due to the temperature allowing for maximum metabolism. The enzymes are most efficient at their highest metabolism and activity.
Auto-trophic activity in plant cells is most closely associated with the organelles called chloroplasts.
Enzymes are catalytic molecules that speed up the rates of reactions.(a) Explain why enzymes are necessary in biological systems.(b) Discuss three control mechanisms that regulate enzymatic activity.A) Enzymes decrease the amount of activation energy required for chemical reactions to occur.B) 1. Cofactors and Coenzymes- Inorganic ions and non protein organic molecules that are necessary to be present on the active site for some enzymes to work. These cofactors participate in the reaction and may even accept or contribute atoms to the reactions.2. Competitive and Noncompetitive inhibition- Limits the enzyme activity. This occurs when a molecule binds to an enzyme, either on the active site or allosteric site, and decreases its activity.3. Allosteric Regulation- Causes a different shape in the enzyme. May either inhibit or stimulate an enzymes activity.
