10) What is one of the ways that the membranes of winter wheat are able to remain fluid when it
is extremely cold? by increasing the percentage of cholesterol molecules in the membrane B) by
decreasing the number of hydrophobic proteins in the membrane C) by increasing the percentage
of unsaturated phospholipids in the membrane D) A and B E) A, B, and C A) 11) All of the
following statements about membrane structure and function are true except: A) Diffusion of
gases is faster in air than across membranes. B) Diffusion, osmosis, and facilitated diffusion do
not require any energy input from the cell. C) Special membrane proteins can cotransport two
solutes by coupling difusion with active transport. D) Both sides of a membrane are identical in
structure and function. E) Voltage across the membrane depends on an unequal distribution of
ions across the plasma membrane.
Solution
10) The correct option is C. by increasing the percentage of unsaturated phospholipids in the
membrane.
The membranes of winter wheat are able to remain fluid when it is extremely cold by increasing
the percentage of unsaturated phospholipids in the membrane. It maintains the fluidity in the
membrane at cold temperatures.
11) The correct option is D. Both sides of a membrance are identical in structure and function.
A membrane is a mosaic of different proteins, which are present and dispersed in the
phospholipid bilayer. These proteins vary in both structure and function and occur in two
different spatial arrangements.Their structure has both a hydrophilic region and a hydrophobic
region.
