Question

There are two pathways for transporting proteins from the cytosol to the [____]. In both

pathways, [____] proteins are delivered to the stroma and the N-terminal import sequence is cleaved to

reveal the thylakoid-targeting sequence. In the SRP-dependent pathway, proteins closely resembling the

bacterial SRP help mediate movement into the lumen. In the pH-dependent pathway, [____] and a pH

gradient across the inner membrane are needed for transport of the [____] protein into the thylakoid
