Multiple Choice
In enzyme catalysis, what happens to an enzyme molecule after it catalyzes a reaction and releases the products?
A
It is converted into product as part of the reaction stoichiometry.
B
It becomes irreversibly denatured as a normal consequence of catalysis.
C
It is permanently consumed and must be resynthesized for each reaction cycle.
D
It returns to its original state and can catalyze another reaction cycle.
Verified step by step guidance1
Understand the role of an enzyme in catalysis: enzymes act as biological catalysts that speed up chemical reactions without being consumed or permanently altered in the process.
Recall that during catalysis, the enzyme binds to the substrate to form an enzyme-substrate complex, facilitating the conversion of substrate into product.
After the reaction occurs, the product is released from the enzyme's active site, freeing the enzyme.
Recognize that the enzyme returns to its original conformation and chemical state after releasing the product, allowing it to participate in additional reaction cycles.
Conclude that enzymes are not consumed or permanently changed by the reactions they catalyze, which is why they can be reused multiple times.
