How do wind patterns and land masses in the northern pacific affect ocean surface currents in the northern pacific

they act as barriers to their natural paths

Explanation:

"Located on either side of the major oceans (including the Atlantic, Indian, and Pacific), land masses affect currents because they act as barriers to their natural paths. ... The basic wind patterns that drive the currents in both hemispheres are the trade winds and the westerly winds"

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
