Enzymes are biomolecules that catalyze (i.e., increase the rates of) chemical reactions. Almost all enzymes are proteins. In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
What else can I help you with?
How do you enzymes reach the part of the cell in which they are needed?
Enzymes are typically produced in specific organelles within the cell, such as the cytoplasm or the endoplasmic reticulum. They are then transported to their target location within the cell through vesicles or the endomembrane system. Once at the desired location, enzymes can either act within that organelle or be secreted outside the cell.
What part of a cell contains many enzymes?
The cytoplasm is the part of the cell that contains many enzymes. Enzymes catalyze biochemical reactions within the cell, helping to regulate various cellular processes.
How many enzymes are in one cell?
There can be thousands of different enzymes in a single cell. Each enzyme has specific functions that help catalyze and regulate the various chemical reactions that occur within the cell. The number and types of enzymes present in a cell can vary depending on the cell type and its metabolic needs.
Why dont enzymes digest the cell itself?
The reason why a lysosome does not digest itself or the cell is because it has an inner membrane that is coated with glycocalyx. This membrane contains poly-lactosamine which prevents the digestive enzymes from gaining access.
Which cell organelle controls the synthesis of enzymes?
The endoplasmic reticulum controls the synthesis of enzymes in a cell. It is responsible for assembling, storing, and transporting proteins, including enzymes, to where they are needed within the cell.

Which Cell organelle fuses with a vesicle for purposes of digestion?
The lysosome fuses with a vesicle for the purpose of digestion within the cell. Lysosomes contain enzymes that break down molecules into smaller components that can be used by the cell for energy or recycled for other processes.
How many enzymes are in one cell?
There can be thousands of different enzymes in a single cell. Each enzyme has specific functions that help catalyze and regulate the various chemical reactions that occur within the cell. The number and types of enzymes present in a cell can vary depending on the cell type and its metabolic needs.
What do peroxisomes do for the cell?
Peroxisomes contain enzymes which metabolize hydrogen peroxide within the cell, hence the name.
Where within a cell are catalyst synthesized?
Enzymes are natural catalysts produced by cells, and all enzymes are proteins made in the cytoplasm of the cell by translation of genetic material (mRNA).
What has enzymes to help destroy cells?
Apoptotic enzymes, such as caspases, are responsible for initiating and executing the process of programmed cell death (apoptosis). These enzymes target specific molecules within the cell to induce its breakdown and ultimately lead to cell death.
What is autophagocytosis?
Autophagocytosis is the process of self-digestion by a cell through the action of enzymes originating within the same cell.
What contains enzymes that are used to degrade foreign particles as well as cell structures?
Lysosomes contain enzymes that are used to degrade foreign particles as well as cell structures. These enzymes help break down substances such as bacteria, viruses, and damaged organelles within the cell.
Are chemical reactions within cell promoted by enzymes or proteins?
I guess that the correct answer to that is enzymes. Enzymes, on the other hand, are proteins. Therefore, this is also one of the functions that proteins have.
Why dont enzymes digest the cell itself?
The reason why a lysosome does not digest itself or the cell is because it has an inner membrane that is coated with glycocalyx. This membrane contains poly-lactosamine which prevents the digestive enzymes from gaining access.
