All reactions, even exergonic, need an activation energy to happen. Enzymes provide that activation energy. Sometimes by their R groups, sometimes by stressing bonds in a molecule in their activation site and sometimes by only providing a space apart from the cytosol in their activation site for two substrates to react.

What are the General steps in enzyme catalyzed reaction?
In an enzyme-catalyzed reaction, the general steps include: substrate binding to the active site of the enzyme, forming an enzyme-substrate complex. This complex undergoes a reaction, leading to the formation of products. Finally, the products are released from the enzyme, which remains unchanged and can continue catalyzing more reactions. The enzyme facilitates the reaction by lowering the activation energy required for the reaction to occur, increasing the reaction rate.
General properties of enzyme?
they are more specific and the remain unchang after the completion of the reaction
What is a substrate in the context of enzyme reaction?
Enzyme-substrate specificity means that a substrate can fit into an enzyme similar to a key fitting into a lock. The active site of the enzyme is what determines its specificity. An enzyme can hence catalyze a reaction with a specific substrate, such as amylase catalyzing starch molecules. During these reactions, the substrate is held in a precise optimum position to create and break bonds, catalyzing the molecule.
What is an active site and what is its relationship to an enzyme?
an active site in an enzyme is the area that breaks the bond in its substrate. E.g. a maltose molecule's glycocide bond is broken by the active site in a maltase enzyme.
What causes molecules to change?
I think this refers to catalysts as these are considered not to be changed by a reaction-- sometimes this true when molecules react on the surface of a catalyst bu sometimes the catalyst does get involved in the chemical reaction- but is regenerated.
How does an enzyme influence a biological reaction?
An enzyme influences a biological reaction by speeding up the reaction without being consumed in the process. Enzymes lower the activation energy needed for a reaction to occur, making it easier and faster for the reaction to take place. This allows biological processes to happen more efficiently in living organisms.
How does an enzyme influence the rate of a biological reaction?
Enzymes speed up biological reactions by lowering the activation energy needed for the reaction to occur. This allows the reaction to happen more quickly and efficiently.
When an enzyme affects a chemical reaction it its acting as a biological?
It is acting as a biological catalyst.
What speeds up biological chemical reaction?
enzyme
What is a biological cayalyst?
A biological catalyst is a substance, usually a protein (such as an enzyme), that increases the rate of a biochemical reaction without being consumed in the process. It lowers the activation energy required for the reaction to occur, making the reaction proceed more quickly.
Complete the sentence when an enzyme affects a chemical rection it is acting as a biological?
catalyst. An enzyme speeds up the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. This allows the reaction to happen more quickly and efficiently within biological systems.
What is a biological catalyst protein called?
A biological catalyst protein is called an enzyme. Enzymes speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur.
A biological catalyst or chemical reaction facilitator is known as?
A biological catalyst increases the rate of biological processes/biological reactions. A biological catalyst (enzymes) act to lower the activation energy of a chemical reaction. Enzymes are bilogical catalysts that bind or separate substrates (chemicals the catalysts act on). the 'lock and key' model suggests that the enzyme doesn't change its form and only similarly shaped substrates can fit into the lock or cleft. it is similar to the toy children play with where you must fit the circular block into the circular hole and so on. The 'induced fit' model says thatthe enzyme molds itself around the substrate and separates or binds it from there. hope i helped!
What does biological catalyst mean?
Enzymes are biological catalysts. This means they speed up a chemical reaction, but are not broken down or changed by it. They lower the amount of energy required for a chemical reaction to tack place.
What is a substrate effector?
A substrate effector is a molecule that can bind to an enzyme's substrate and either enhance or inhibit the enzyme's activity. This can influence the rate of the enzyme-catalyzed reaction.
Why do you need a catalyst during a enzyme reaction?
A catalyst speeds up the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. In the case of an enzyme-catalyzed reaction, the enzyme serves as a biological catalyst, allowing the reaction to occur more efficiently and at lower energy levels than it would without the enzyme.
An example of a biological catalyst?
An example of a biological catalyst is an enzyme. Enzymes are proteins that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. They are specific in their action and can catalyze a wide range of biochemical reactions.
