Final answer:
The sequence described is a metabolic pathway, and it involves a series of enzymatic reactions that transform a substrate to a final product through various intermediates. These pathways can either be anabolic, requiring energy, or catabolic, producing energy.
Step-by-step explanation:
A sequence of enzymatic reactions that begins with an initial substrate, progresses through a number of intermediates, and ends with a final product is known as a metabolic pathway. These can be anabolic pathways, which require energy to build complex molecules from simple ones, or catabolic pathways, which produce energy by breaking down complex molecules into simpler ones. The process of enzymatic reactions involves substrates binding to an enzyme's active site, forming an enzyme-substrate complex, and undergoing a transformation to release the final product.
An example provided in LibreTexts™ illustrates how substrate A is converted to product D through the action of three enzymes and the formation of two intermediate products, B and C. This exemplifies how each enzyme in a pathway is specific to the reaction it catalyzes due to the specificity of the active site.
Enzymes greatly increase the rate of chemical reactions by lowering the activation energy needed for the reaction to proceed, thereby facilitating the transformation from reactants (substrates) to final products efficiently.
