Question

To ensure that biochemical pathways proceed in the correct sequence, the cell employs different __________ to catalyze each reaction.

Answer 1

Enzymes are used in cells to catalyze biochemical pathways and ensure that reactions proceed in the correct sequence.

Step-by-step explanation:

Enzymes are employed in the cell to catalyze each step of biochemical pathways, ensuring that the reactions proceed in the correct sequence. These enzymes serve as catalysts, facilitating the chemical reactions and increasing their rates without being consumed in the process. By providing a specific active site for each reaction, enzymes ensure that the correct substrates are bound and transformed into the desired products.

Answer 2

To ensure that biochemical pathways proceed in the correct sequence, the cell employs different enzymes to catalyze each reaction. Enzymes are involved in anabolic pathways that require energy and are regulated by mechanisms like feedback inhibition and allosteric regulation.

Step-by-step explanation:

Cells utilize distinct enzymes to catalyze each step in biochemical pathways, ensuring proper sequence and regulation. These enzymes are crucial for the regulation and facilitation of metabolic processes. For instance, in anabolic pathways, enzymes are needed to assemble small molecules into larger, complex ones, a process that requires energy input.

Additionally, enzymes play a pivotal role in feedback inhibition—a regulatory mechanism in which the end product of a pathway inhibits an upstream step, preventing the overaccumulation of the final product and conserving cellular resources. Allosteric regulation is another way to fine-tune enzyme activity, where molecules such as ATP, ADP, and NADH bind to enzymes non-covalently, modifying their activity to meet the cell's metabolic demands.
