Draw the most likely orientation of the protein if it is transported to the plasma membrane. label the approximate size of the domains. this does not need to be turned in but do it on your own as a though problem.

Hope it helps

Explanation: Integral membrane proteins- they pass through the lipid bilayer and hang around on the exterior as well

Peripheral proteins- they hang around the exterior of the membrane.

Lipid anchored proteins- The also hang out on the exterior of the membrane but are covalently attached to the of the lipid group that is within the membrane

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
