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.

. How do enzymes aid in cell regulation?
Enzymes speed up reactions that help sustain life.
Lysosomes contain enzymes which function where?
Lysosomes contain hydrolytic enzymes. These enzymes break down large food particles, worn out organelles, or intruders in a cell (e.g. bacteria, viruses). Hydrolytic enzymes work best in the acidic environment that the lysosome provides.
Outline four functions of proteins within the cell membrane?
There are four functions of proteins within the cell membrane. The four functions of proteins are active transport, cell recognition, cell communications, and are used as enzymes in the cell membrane.
What is sap and what does it do?
the sap in the cell is the matrix in which the organelles of the cell are found and it's responsible for the metabolic reactions of the cell due to the presence of enzymes within it ......... there is also nuclear sap
How many enzymes are in one cell?
There are lots of enzymes in a cell, and from cell to cell, it varies how much enzymes each has. Also some cells make enzymes and secrete it outside.
. How do enzymes aid in cell regulation?
Enzymes speed up reactions that help sustain life.
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 is autophagocytosis?
Autophagocytosis is the process of self-digestion by a cell through the action of enzymes originating within the same 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.
Lysosomes contain enzymes which function where?
Lysosomes contain hydrolytic enzymes. These enzymes break down large food particles, worn out organelles, or intruders in a cell (e.g. bacteria, viruses). Hydrolytic enzymes work best in the acidic environment that the lysosome provides.
Outline four functions of proteins within the cell membrane?
There are four functions of proteins within the cell membrane. The four functions of proteins are active transport, cell recognition, cell communications, and are used as enzymes in the cell membrane.
What role do lysosomes play in an animal cell?
Lysosomes contain enzymes that are responsible for the breakdown of waste products and debris within the cell.
What is the source of enzymes?
Enzymes are produced within the cell by ribosomes.
What is the digest Center in a cell?
The lysosome is the organelle within a cell that serves as its digestion center. Lysosomes use enzymes to carry out those functions.
What is sap and what does it do?
the sap in the cell is the matrix in which the organelles of the cell are found and it's responsible for the metabolic reactions of the cell due to the presence of enzymes within it ......... there is also nuclear sap
What do lysosomes do in a animal cell?
Lysosomes are a cell's "recycling centers", consuming dead organelles or forign substances and breaking them down with the hydrolytic enzymes within them.
