Bob, a biologist who was researching a new eukaryotic unicellular species, wanted to study a particular protein Y. After obtaining and purifying the sample, Bob discovered that this protein had 3 subunits: A, B, and C. Through substantive scientific analysis, Bob discovered that protein Y operated in a membrane; however, he could not deduce which particular membrane. Nonetheless, Bob found that only subunit B was traversed through the interior of the membrane. With Bob’s findings, please answer the following questions.

What is the highest order of protein structure exhibited by Bob’s protein?
