The transportation and transformation of metabolites are necessary for life. These are made possible by metabolic pathways and transport systems, those are vital to cellular function. These pathways comprise of oxidative phosphorylation, citric acid cycle, and glycolysis those are highly controlled and linked in order to maintain homeostasis, biosynthesis, and creation of cellular energy. Metabolites can migrate across cellular membranes allowing various types of transport processes, including as passive diffusion, assisted diffusion, and active transport, which guarantee their availability in the appropriate compartments at the appropriate times. The various metabolic pathways and complex transport systems that regulate metabolite flux within cells are examined in this review. We examine the workings of important transporters, including the solute carrier (SLC) families and ATP-binding cassette (ABC) transporters, emphasising their regulatory functions and selectivity in preserving metabolic homeostasis. Comprehending these mechanisms yields knowledge regarding cellular metabolism and its disruption in illnesses, presenting prospective treatment avenues for metabolic conditions.
