Which lists the correct order of steps involved in the formation of an enzyme-substrate complex?(1 point) Responses
chemical reaction takes place > products are released > enzyme binds to substrate at active site > enzyme-substrate complex forms
enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place
enzyme binds to substrate at active site > chemical reaction takes place > products are released > enzyme-substrate complex forms
enzyme-substrate complex forms > enzyme binds to substrate at active site > chemical reaction takes place > products are released
enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place > products are released
pick ONE of the responses given please
enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place
The correct order of steps involved in the formation of an enzyme-substrate complex is:
1. Enzyme binds to substrate at the active site.
2. Enzyme-substrate complex forms.
3. Chemical reaction takes place.
4. Products are released.
So, the correct response is:
enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place > products are released
To determine the correct order of steps involved in the formation of an enzyme-substrate complex, we need to understand the process.
1. The first step is the enzyme binding to the substrate at the active site. The active site is a specific region on the enzyme where the substrate molecule binds.
2. Once the enzyme and substrate are bound together at the active site, they form an enzyme-substrate complex. This complex is a temporary structure in which the enzyme and substrate are chemically linked.
3. After the enzyme-substrate complex forms, a chemical reaction takes place. The enzyme facilitates this reaction by lowering the activation energy required for the reaction to occur. This allows the substrate to be converted into the desired product(s).
4. Finally, after the chemical reaction occurs, the products are released from the active site. The enzyme is then free to bind to another substrate molecule and repeat the process.
Now, let's look at the provided options to identify the correct order:
A. chemical reaction takes place > products are released > enzyme binds to substrate at active site > enzyme-substrate complex forms
This option is not correct because it suggests that the enzyme binds to the substrate after the chemical reaction takes place, which is not accurate.
B. enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place
This option is correct. The enzyme first binds to the substrate, forming the enzyme-substrate complex, and then the chemical reaction occurs.
C. enzyme binds to substrate at active site > chemical reaction takes place > products are released > enzyme-substrate complex forms
This option is not correct because it suggests that the enzyme-substrate complex forms after the chemical reaction takes place, which is not accurate.
D. enzyme-substrate complex forms > enzyme binds to substrate at active site > chemical reaction takes place > products are released
This option is not correct because it suggests that the enzyme-substrate complex forms before the enzyme binds to the substrate, which is not accurate.
Therefore, the correct order of steps involved in the formation of an enzyme-substrate complex is:
enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place
