Question

HURRY!!! | The diagram shows an energy-coupled reaction of glucose metabolism and protein synthesis. Energy-coupled reactions pair reactions that require energy with reactions that produce energy.

Which of the following correctly identifies the reactants and energy requirements of these reactions?

A) Reactant 1 = amino acids; Reactant 2 = glucose; A = ATP; B = ADP
B) Reactant 1 = glucose; Reactant 2 = amino acids; A = ADP; B = ATP
C) Reactant 1 = glucose; Reactant 2 = amino acids; A = ATP; B = ADP
D) Reactant 1 = amino acids; Reactant 2 = glucose; A = ADP; B = ATP

Answer 1

Reactant 1 = glucose; Reactant 2 = amino acids; A = ATP; B = ADP. Hence the correct option is c.

In this interconnected system, glucose metabolism and protein synthesis are intricately linked through energy-coupled reactions. Glucose, serving as Reactant 1, participates in a process that demands energy, and this energy is supplied by the hydrolysis of ATP (adenosine triphosphate), transforming it into ADP (adenosine diphosphate). Concurrently, amino acids (Reactant 2) engage in a reaction that yields energy, with ADP being phosphorylated back into ATP.

This coupling of reactions is fundamental for cellular activities, ensuring a harmonious balance between energy-consuming processes like protein synthesis and energy-yielding processes like glucose metabolism. The orchestrated interplay of these reactions is crucial for maintaining the cell's energy homeostasis and supporting vital functions. The diagram underscores the dynamic nature of cellular processes and the strategic utilization of energy to drive essential biochemical reactions. Hence the correct option is c.
