Enzymes act as biological catalysts that speed up metabolic reactions by lowering the activation energy required for the reaction to occur. They bind to specific substrates, facilitating the conversion of these substrates into products while remaining unchanged themselves. This efficiency allows metabolic pathways to proceed quickly and under mild conditions, essential for sustaining life. Without enzymes, many biochemical reactions would occur too slowly to support vital processes.
What else can I help you with?
How enzyme accelerate metabolic reaction?
Enzymes lower the activation energy required to start the reaction.
What compounds catalyze metabolic reactions?
They are called enzymes; each one is specific for one metabolic reaction.
What describes a protein that states or quickens a chemical reaction?
a catalystbut most specifically an enzymebecause it asked for a protein.
What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
The end product of a metabolic pathway can bind to the enzyme involved in the beginning of the pathway, acting as an inhibitor. This typically changes the shape of the enzyme's active site, preventing the enzyme from binding to its substrate and carrying out the reaction. This regulatory mechanism is known as feedback inhibition.
Which of the following is not used to determine metabolic activity?
Temperature is not typically used to determine metabolic activity, as metabolism is more directly influenced by factors such as enzyme activity, substrate availability, and hormonal regulation. Temperature can indirectly affect metabolic rate by influencing enzyme function and reaction rates.
How does enzyme accelerate metabolic reaction?
by lowering the activation energy needed

Which is accurately describes an enzyme?
An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. Enzymes are highly specific, meaning they only catalyze one particular reaction or a group of closely related reactions. They are not consumed in the reaction and can be used repeatedly.
What describes a protein that states or quickens a chemical reaction?
a catalystbut most specifically an enzymebecause it asked for a protein.

This regulatory mechanism is known as feedback inhibition.
Which component is released from the active site of an enzyme during a chemical reaction?
The product of the chemical reaction is released from the active site of an enzyme. The substrate is converted into product during the enzymatic reaction, and once the reaction is complete, the product is released to allow the enzyme to catalyze another reaction.
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.
Which of the following is not used to determine metabolic activity?
Temperature is not typically used to determine metabolic activity, as metabolism is more directly influenced by factors such as enzyme activity, substrate availability, and hormonal regulation. Temperature can indirectly affect metabolic rate by influencing enzyme function and reaction rates.
What name is given to the molecules made in an enzyme controlled reaction?
The molecules made in an enzyme-controlled reaction are usually referred to as products. These products are the result of the substrate molecules being transformed by the enzyme during the reaction.
What is the chemical that helps a chemical reaction without being consumed during a reaction?
ENzyme
Which method of enzyme control is when the products of a reaction inhibit the working of an enzyme by binding to the enzyme?
The method of enzyme control where the products of a reaction inhibit the enzyme by binding to it is known as feedback inhibition. In this process, the end product of a metabolic pathway binds to an enzyme involved in the pathway, reducing its activity and preventing the overproduction of the product. This regulatory mechanism helps maintain homeostasis and balance within the cell.
