Actually, enzymes are not used up in chemical reactions; instead, they can catalyze multiple reactions over time. They lower the activation energy required for reactions, allowing them to proceed more quickly. After facilitating a reaction, the enzyme is released unchanged and can be reused to catalyze additional reactions. This efficiency is a key reason why enzymes are essential for biological processes.

What type of protein regulates nearly all chemical reaction in a cell?

Enzymes are the type of protein that regulate nearly all chemical reactions in a cell by speeding up the reactions. They act as catalysts and play a vital role in maintaining cellular function and metabolism.


What are the key properties of enzymes and what is their function in biological system?

Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level, a cell is really a little bag full of chemical reactions that are made possible by enzymes! Enzymes are made from amino acids, and they are proteins. When an enzyme is formed, it is made by stringing together between 100 and 1,000 amino acids in a very specific and unique order. The chain of amino acids then folds into a unique shape. That shape allows the enzyme to carry out specific chemical reactions -- an enzyme acts as a very efficient catalyst for a specific chemical reaction. The enzyme speeds that reaction up tremendously.


A sentence with the word enzyme?

A cell contains thousands of different types of enzyme molecules, each specific to a particular chemical reaction.


A chemical reaction in a living cell occurs in the presence of a specific protein molecule The concentration of this protein molecule remains the same before and after the reaction This protein mole?

This protein molecule is likely an enzyme, which facilitates the chemical reaction by lowering the activation energy required for the reaction to occur. Enzymes remain unchanged after the reaction and can be reused to catalyze multiple reactions. They are specific to the reaction they catalyze and are essential for the proper functioning of the cell.


What is the catalyst in a metabolic pathway?

A catalyst in a metabolic pathway is typically an enzyme that speeds up the rate of a specific chemical reaction without being consumed in the process. Enzymes achieve this by lowering the activation energy required for the reaction to occur, allowing metabolic processes to proceed efficiently within the cell.

What is the name of region at which reactants bind to an enzyme during a biochemical reaction?

The region where reactants bind to an enzyme during a biochemical reaction is called the active site. It is a specific region on the enzyme where the substrate binds, forming an enzyme-substrate complex that leads to the catalysis of the reaction.
