An analysis of plasma or nuclear membrane would yield
A) cellulose and chitin.
B) suberin and cutin.
C) phospholipids and proteins.
D) microtubules and microfilaments.
E) phospholipids and nucleic acids.

Question

Quizplus · Accepted Answer

Plasma and nuclear membranes are composed primarily of phospholipids and proteins. Phospholipids are the main building block of these membranes, forming a lipid bilayer, while proteins are embedded within the membrane, performing a variety of functions such as transporting molecules in and out of the cell and serving as receptors. While cellulose and chitin are structural components found in cell walls and suberin and cutin are found in the cuticle of plants, they are not present in plasma or nuclear membranes. Microtubules and microfilaments are components of the cytoskeleton and nucleic acids are found primarily in the nucleus, neither of which are major components of plasma or nuclear membranes.
