Enzymes are catalysts. They help lower the activation energy of reactions and increase the rate of the reaction. Without the help of enzymes, the biochemical reactions in the body would take so long that it would kill the person.

What do enzymes do in the cell?

Enzymes are protein molecules that catalyze biochemical reactions in the cell. They speed up reactions by lowering the activation energy required for a reaction to occur, allowing processes to happen more efficiently. Enzymes are specific in their actions and can be regulated to control the cell's chemical reactions.


What accelerates chemical reactions that occur in the human body?

Enzymes are biological molecules that accelerate chemical reactions in the human body by lowering the activation energy needed for the reactions to occur. Enzymes are highly specific and work by binding to specific substrates to catalyze a specific reaction. Temperature and pH can also affect the rate of chemical reactions in the body.


How enzymes affect reactions?

Enzymes lower the activation energy required for reactions to occur


What type of catalysts effect biochemical reactions?

Enzymes are the most common type of catalyst that affect biochemical reactions. They are proteins that facilitate specific chemical reactions in living organisms, speeding up the reaction without being consumed in the process.


What is the effect that enzymes have on certain chemical reactions in living things?

Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.


How does an inhibitor affect the rate of chemical reaction?

An inhibitor reduces the rate of a chemical reaction by slowing down or preventing the reaction from occurring. It does this by interfering with the active sites of enzymes or by changing the overall reaction pathway, ultimately making it more difficult for the reaction to proceed at its normal rate.


When do chemical reactions involving enzymes slow down?

Chemical reactions involving enzymes slow down when the temperature is too high or too low, as enzymes have an optimal temperature range for activity. Additionally, changes in pH levels can also affect enzyme activity, causing reactions to slow down. Lastly, the presence of inhibitors or competitive molecules can hinder enzyme function, leading to a slowdown in reactions.


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.


How does temperature affect the chemical reactions of certain substances?

IT ACCELATATES THE CHEMICAL REACTIONS


How do enzymes affect reactions?

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur. They do this by binding to reactant molecules and bringing them together in the correct orientation to facilitate the reaction. Enzymes are specific to certain substrates, so they only catalyze specific reactions.


How are enzymes important to chemical reactions in cells?

Enzymes are proteins that speed up chemical reactions in the body. They aid in processes like digestion. They break down proteins into amino acids and carbohydrates into sugars. Enzymes usually have the suffix -ase. Sucrase, for example breaks down sucrose into glucose and fructose. Urease breaks down urea into ammonia and carbon dioxide.


What aspects of chemical reaction are enzymes known to affect?

Enzymes affect the speed of reactions predominantly. In some instances in which more than one reaction is possible, enzymes increase the speed of the normally slower reaction enough to make it predominate, while the other possible reaction is effectively suppressed.
