An electrochemical Gradient
Explanation:
During the translation of mRNA to protein, the nascent polypeptide chain that is formed is not yet a functional protein right after translation. The polypeptide must then undergo another series of processing and packaging and may even need another protein(s) to completely form a functional moiety. Generally, for this a mix of chaperones may be needed to complete the protein synthesis pathway.
