Question

In the lipid bilayer of a cell membrane the hydrophobic heads are on the inner and outer surface and the hydrophilic tails in the middle. the hydrophilic heads are on the inner and outer surface and the hydrophobic tails in the middle. there is a random arrangement of phospholipids. the hydrophilic heads are on the inner and outer surface and cholesterol is in the middle. cholesterol is on the inner and outer surface and phospholipids are in the middle. The interior of a lipid bilayer is the hydrophilic region. True False What statement is incorrect about this oxidation-reduction reaction? 2 SO_2(g) + O_2 (g) rightarrow 2 SO_3(g) sulfur is oxidized. O_2 is the oxidizing agent. sulfur is reduced. SO_2 is the reducing agent. Margarine containing partially hydrogenated soybean oil is solid because It contains only saturated fats. it contains only trans fatty acids.

Explanation / Answer

1) hydrophillic heads on inner and outer surfaces and hydrophobic tails are in the middle.

2) false. beacause the interior of lipid bilayer is hydrophobic region and water repelling.

3) sulfur is oxidized. since its oxidation state has changed from + 4 to +6 . oxygen is reduced.

hope this helps
