Question

large, complex molecules in the peach into smaller, usable nutrients. this breakdown is a chemical reaction that would normally take a very long time, but it happens quickly and efficiently thanks to enzymes. these specialized proteins act as biological catalysts, speeding up the chemical reactions without being used up in the process. each enzyme has a specific shape with a unique active site, a special region where a specific reactant molecule, called a substrate, can fit. just like a key fits into a lock, the substrate binds to the active site. once bound, the enzyme helps transform the substrate into a new molecule called a product, which your body can then absorb and use. in the process of digesting the peach, the sugar molecules are the reactants that bind to the digestive enzyme. using the lock - and - key model, what would you call the sugar molecules in this reaction, and which part of the enzyme would they bind to? they are the enzymes that bind to the enzymes substrate they are the products that bind to the enzymes active site they are the substrates that bind to the enzymes active site they are the catalysts that bind to the enzymes product

Explanation:

According to the lock - and - key model and the description of enzyme - substrate reactions, the reactant molecule that binds to the enzyme's active site is called the substrate. In the digestion of a peach, sugar molecules are reactants that bind to digestive enzymes. So they are substrates that bind to the enzyme's active site.

Answer:

C. They are the substrates that bind to the enzyme's active site
