Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.
