The correct terms are given below:

Blank	Term
	E.coli
	Proteins
	Metabolic Pathway
	Environment
	Operator
	Promoter
	Repressor

Explanation of Solution

An operator is a set of gene in E.coli. These genes together make proteins that work in a metabolic pathway. An operon which can respond to changes in the environment. Operator is a segment of gene that act as a switch for controlling the transcription. When the operon is on, RNA polymerase binds the promoter and transcribes the DNA. When operon is off, repressor block transcription.
