Enzymes, such as the one shown in the picture, work by fitting onto the substrate molecule like a lock-and-key action. Which statement is true, with regard to the enzyme and the substrate?

Answer 1

The statement "Enzymes, such as the one shown in the picture, work by fitting onto the substrate molecule like a lock-and-key action" implies that:

The enzyme has a specific shape or active site that matches the shape of the substrate molecule. This specificity allows the enzyme to bind to the substrate molecule, forming an enzyme-substrate complex. The enzyme then catalyzes a specific chemical reaction on the substrate, converting it into a product.

In summary, the true statement regarding the enzyme and the substrate is that enzymes have a specific shape or active site that fits the substrate molecule, allowing them to form an enzyme-substrate complex and catalyze a specific reaction.
