I think topic 4 is the most important one and topic 1 including protein structure and fluid mosaic membrane.

Most probably topic 1( protein structure and fluid mosaic). I doubt they'd ask anything about topic2 since it's all related to heart and blood circulation which is completely different from what we're taking now in unit 4.

yeah thanks. Also in unit 2 don't forget drug trial testing, they've asked about the phases before.
