Chloride ion (Cl-) concentrations must be maintained much higher outside of cells than inside of cells. How this gradient is maintained is complex, but a key transporter co-transports Cl- along with K+ ions. The name of this transport protein could be and its mode of transport would be

Explanation:

Such type of the integral membrane proteins that that plays important role in the transport of many ions or molecules across the membrane at a same in the same direction is called as symporters such as K+/Cl- symporter and some other. Such type of transport in which energy is required is called active transport. When energy is required in inward direction then called indirect active transport.

answer; (phospholipid);

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:
