Question

a substrate is a substance that is affected by an enzyme. in order for an enzyme to be effective, it must
a.
bind to a substrate, transform itself into
more of the substrate, and release higher
amounts of the substrate as a product.
b.
bind to a substrate, transform itself and
the substrate into products, and cause
these products to dissolve.
c.
bind to a substrate, transform itself into
products, and release these products.
d.
bind to a substrate, transform the
substrate into products, and release the
products.

Explanation:

To solve this, we recall the function of enzymes: Enzymes are biological catalysts that bind to substrates, convert them into products (without being consumed or transformed themselves), and then release the products.

• Option A: Enzymes don't produce more substrate; they act on it. Eliminate A.
• Option B: Enzymes don't transform themselves, and dissolving products isn't part of their core function. Eliminate B.
• Option C: Enzymes are not transformed into products (they are reusable catalysts). Eliminate C.
• Option D: Matches the enzyme - substrate interaction: bind to substrate, transform substrate to products, release products.

Answer:

D. bind to a substrate, transform the substrate into products, and release the products.
