How do enzymes catalyze a reaction to increase the rate of chemical processes in biological systems?
Enzymes speed up chemical reactions in living organisms by lowering the amount of energy needed for the reaction to occur. They do this by binding to specific molecules, called substrates, and bringing them together in a way that makes it easier for the reaction to happen. This process, called catalysis, allows biological processes to occur much faster than they would without enzymes.

What is the function of an enzyme?
Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. They are highly specific and can catalyze a wide range of reactions within cells.
A substance that causes or that speeds up a chemical reaction while the substance itself remains unchanged?
catalyst
What is the importance of enzymes in a biological process?
Enzymes are important in biological processes because they act as catalysts, speeding up chemical reactions that are essential for life to occur. They help break down molecules, build new molecules, and regulate biochemical pathways. Without enzymes, many biochemical reactions would proceed too slowly to sustain life.
What is the purpose of having enzymes within a cell?
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 are three statements that describe an enzyme?
1. It is not used up and does not change shape in a reaction. 2. It is used to speed up a reaction 3. Will only bind to another molecule as long as the enzyme substrate complex can form(see lock and key theory)
Do enzymes increase the activation energy of the reactions they catalyze?
yes because enzymes are highly weighted proteins which produced from living cells and used in industrial and biological processes
Do most enzymes increase the activation of the energy reactions they catalyze?
yes because enzymes are highly weighted proteins which produced from living cells and used in industrial and biological processes
Do most enzyme increase the activation energy of the reaction they catalyze?
yes because enzymes are highly weighted proteins which produced from living cells and used in industrial and biological processes
What does an increase in temperature result to?
An increase in temperature can lead to the expansion of materials, a change in state (for example, from solid to liquid), an increase in the speed of chemical reactions, and can also cause biological processes to speed up or slow down.
What protein catalyst facilitates chemical reactions?
Enzymes are protein catalysts that facilitate chemical reactions by reducing the activation energy required for the reaction to occur. Enzymes are essential for many biological processes and can increase the rate of reactions by millions of times.
Are enzymes affected by the chemical reaction they speed up?
Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.
How is the term catalyst related to the term enzymes?
Enzymes are biological catalysts that speed up chemical reactions in living organisms. Catalysts, in general, are substances that increase the rate of a chemical reaction without being consumed in the process. Enzymes are a specific type of catalysts that are essential for various biological processes.
How chemicals build up?
Chemicals can build up in the environment through various processes such as bioaccumulation, where they accumulate in the tissues of organisms, and biomagnification, where they increase in concentration as they move up the food chain. Additionally, chemicals may persist in the environment due to biological or chemical processes that slow down their degradation. Human activities such as industrial processes, agriculture, and improper waste disposal also contribute to the buildup of chemicals in the environment.

How do enzymes affect reactions in living cells?
Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. 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. Enzymes are known to catalyze about 4,000 biochemical reactions.
What is biochemistry in chemical science and in biological science?
Biochemistry uses basic chemistry and organic chemistry principles in order to structurally analyze biological molecules and to explain and predict their interactions in the body. Example: certain proteins are denatured at higher temperatures because the increase of energy causes bonds to disassociate destroying their structure and rendering them useless.
What is the effect of activators on reaction rate?
Activators are substances that increase the rate of a chemical reaction by lowering the activation energy required for the reaction to proceed. They often enhance the activity of catalysts or increase the concentration of reactants. As a result, the presence of activators can lead to a faster reaction rate and improved efficiency in chemical processes. This effect is particularly important in biological systems, where activators can influence enzyme activity and metabolic pathways.
