On active sites of enzymes, substrates bind to form products.
Specific activity is usually expressed as μmol of substrate transformed to product per minute per milligram of enzyme under optimal conditions of measurement.
The rate of a reaction is the concentration of substrate disappearing (or product produced) per unit time (mol-1 L-1 s-1 ).

What are 4 ways enzymes can lower activation energy?
1. orienting(direction) substrates correctly 2. straining substrate bonds 3. Providing a favorable micro environment 4. Covalently bonding to the substrate got the answers from my AP Bio notes....
How does an enzyme influence a biological reaction?
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.
Proteins that help regulate chemical reactions in cells?
No, they are not.
What type of chemical reactions do kinases catalyze?
Kinases are apart of the Transferases in the Enzymes of metabolism. Kinases transfers phosphate between substrates.
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.
The reactants of enzyme - catalyzed reactions are known as?
Substrates
What are the reactants of enzyme-catalyzed reactions know as?
The reactants of enzyme-catalyzed reactions are known as substrates. Substrates bind to the active site of an enzyme, where the reaction takes place. Enzymes help lower the activation energy required for the reaction to occur.
What are reactants that enter enzyme-controlled reactions?
Reactants that enter enzyme-controlled reactions are typically substrates. Substrates are the specific molecules that enzymes act upon to catalyze a biochemical reaction. The enzyme binds to the substrate at the enzyme's active site, where the reaction takes place.
What is the reactants of an enzyme-catalyzed reaction known as?
Reactants. "Substrate" is another possibility.
What is the term used for all the molecule on which an enzyme act?
The term used for all the molecules on which an enzyme acts is "substrates." Enzymes catalyze biochemical reactions by binding to these substrates, facilitating their conversion into products. Each enzyme typically has a specific substrate or a group of related substrates that it acts upon.
What is the region of an enzyme that catalyzes reactions?
The region of an enzyme that catalyzes reactions is known as the active site. This specific area is typically a pocket or groove on the enzyme's surface where substrates bind. The active site has a unique shape and chemical environment that facilitates the conversion of substrates into products, often by lowering the activation energy required for the reaction.
What is the name of the hypothesis that helps explain enzyme functioning?
The lock and key hypothesis explains enzyme functioning. It suggests that enzymes and substrates fit together like a lock and key, with specific enzyme-active sites binding to specific substrates to catalyze reactions.
Is an enzyme specific in terms of which substrates it can bind?
Yes, enzymes are specific in terms of the substrates they can bind. Each enzyme has an active site that can only accommodate certain substrates based on their shape and chemical properties. This specificity allows enzymes to catalyze specific biochemical reactions.
How does the interaction between an enzyme and its substrates change chemical reaction?
Enzymes speed up the chemical reactions because when it forms a complex with its substrates, it reduces the activation energy that the reaction needs to proceed. Remember that the reaction itself is not altered, only the rate of reaction, and that the enzyme is not used or altered in the reactions.

What is a enzyme controlled reaction?
An enzyme-controlled reaction is a biochemical process in which an enzyme acts as a catalyst to accelerate the rate of a chemical reaction without being consumed in the process. Enzymes lower the activation energy required for the reaction to occur, allowing substrates to convert into products more efficiently. These reactions are highly specific, meaning that each enzyme typically catalyzes only one type of reaction or acts on a specific substrate. Enzyme activity can be influenced by factors such as temperature, pH, and the concentration of substrates or inhibitors.
You've discovered an enzyme that can catalyze two different chemical reactions Which of the following is most likely to be correct?
Enzymes are typically specific to certain reactions due to their unique active sites that fit specific substrates. It is unlikely for an enzyme to catalyze two very different reactions, especially if the reactions have significantly different substrates or mechanisms. It is possible for an enzyme to have multiple related functions or to catalyze a series of reactions in a metabolic pathway. Further investigation is needed to determine the validity of the claim.
