When an enzyme brings two substrate molecules?
When an enzyme brings two substrate molecules together, it facilitates their interaction by lowering the activation energy required for the reaction to occur. This process often involves the formation of an enzyme-substrate complex, which positions the substrates in an optimal orientation for a chemical reaction. As a result, the enzyme accelerates the reaction, allowing the substrates to convert into products more efficiently. Ultimately, this enhances the overall reaction rate and specificity of the enzymatic process.
What role does a substrate play in enzyme specificity and function?
A substrate is the specific molecule upon which an enzyme acts, and it plays a crucial role in determining enzyme specificity and function. Enzymes have unique active sites that fit particular substrates, much like a key fits a lock, which ensures that they catalyze specific biochemical reactions. This specificity is essential for maintaining metabolic pathways and cellular functions, as different enzymes interact with distinct substrates to produce particular products. The interaction between the enzyme and substrate also involves factors like shape, charge, and chemical properties, which together influence the efficiency and regulation of the enzymatic 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.
What can effect how the enzyme and substrate come together?
Factors such as temperature, pH, substrate concentration, and the presence of inhibitors or activators can affect how enzymes and substrates come together. Changes in these factors can alter the shape and activity of enzymes, impacting their ability to bind with substrates and catalyze reactions.
How do enzymes make reactions more likely to occur?
Enzymes increase the likelihood of reactions by lowering the activation energy required for the reaction to proceed. They achieve this by stabilizing the transition state and providing an optimal environment for the substrates to interact. Additionally, enzymes can bring substrates together in the correct orientation and facilitate the formation of intermediate states, thereby accelerating the reaction rate. Overall, by enhancing the efficiency of molecular interactions, enzymes make reactions occur more readily.
Which substances fit together like a lock and key?
Enzymes and their specific substrates fit together like a lock and key. Enzymes have specific binding sites that perfectly match the shape of their substrates, allowing for efficient catalysis of specific chemical reactions. This lock-and-key model is essential for the specificity and efficiency of enzyme-substrate interactions.

How do enzymes catalyze reactions and what is the process by which they facilitate chemical reactions?
Enzymes catalyze reactions by lowering the activation energy required for a chemical reaction to occur. They do this by binding to specific substrates and bringing them together in the correct orientation to facilitate the reaction. This process, known as catalysis, speeds up the reaction without being consumed in the process.
Why do enzymes have an active site?
The structure of an enzymes and its active site determine which substrates will work for the enzyme. This is called the lock and key method. The active site is the lock and the substrate is the key.
When mixed together an acid and a base neutralize each other forms?
The products of neutralization reactions are salts and water.
What 2 things can enzymes do to a substrate?
Speeds up the rates of chemical reactions by providing energy for the cell to use. Thus, the cell is not working as hard to perform the task. You need enzymes to survive. That is one of the reasons why a high temperature fever is a problem, the enzymes that help to keep you alive are denaturing (basically being rendered useless) and without them you cannot live.
What name do we give the joined enzyme and substrate that remains together until the reaction is over?
The joined enzyme and substrate are referred to as the enzyme-substrate complex. This complex forms when the substrate binds to the active site of the enzyme, and it remains intact until the enzymatic reaction occurs, resulting in the formation of products. The enzyme itself is then free to catalyze additional reactions.
How do enzymes break things apart and put things together?
Enzymes facilitate biochemical reactions by lowering the activation energy required for the reactions to occur. They achieve this by binding to specific substrates at their active sites, forming an enzyme-substrate complex. In the case of breaking things apart, enzymes may apply stress to chemical bonds, making them easier to break, while in the case of putting things together, they can stabilize the transition state, allowing substrates to combine more efficiently. This specificity and efficiency make enzymes crucial for various metabolic processes in living organisms.
