Answer-A

enzymes are found in cell plasm

I think the answer B means lipoproteins.They are found in the cell membrane.

There are easily 3 forms of cellular membrane proteins: linked ones (loosely linked to the membrane), embeded ones (one section is anchored to the membrane) and transmembrane proteins (one section is interior the cellular one interior the membrane and one protruding) the cellular membrane is a charged lipid bilayer with the unfavourable and watery section dealing with out - so any component of a protein beeing interior a membrane should be negatively charged and/or be lipophillic. The domain names of proteins in a membrane or crossing it tend to be alpha helices. purposes are manifold - for transmembrane proteins the main undemanding are channel or receptor. Channel transport molecules around the membrane and could be gated to close the cellular - in lots of situations a equipment deal of helices making a small pore. receptors attain in the time of yet make no putting out interior the cellular wall - the perfom a structural substitute upon binding of a ligand which leads to activation interior the cellular. membrane certain proteins are in lots of situations places of synthesis or are helping transmembrane proteins (an occasion would be G- protein coupled receptors) - easily the same is going for membrane linked proteins with them beeing waiting to cycle from and to the membranes (an occasion often is the SecA transporter) common platforms: linked and certain proteines have in lots of situations a catalytic midsection the place they convert ATP or GTP while transmembrane proteins lack those

Haha lol, it's lipid because lipids are fats or oils not proteins.
