10. The plasma membrane (A) is composed of an extracellular and intracellular layer of phospholipids. (B) has extracellular and intracellular layers or leaflets that are highly symmetrical. (C) uses cholesterol as its primary lipid. (D) contains cellulose.

17. Wild type bread mold can grow in a minimal medium without supplements, while certain mutated strains can only grow in a minimal medium that is supplemented with specific intermediates. See the figure below for an overview of the arginine biosynthetic pathway. A strain that can grow in a minimal medium containing arginine, but NOT in minimal media containing citrulline nor in minimal media containing ornithine would have a mutation in the gene that encodes for ________. Precursor $\xrightarrow{\text{Enzyme 1}}$ Ornithine $\xrightarrow{\text{Enzyme 2}}$ Citrulline $\xrightarrow{\text{Enzyme 3}}$ Arginine(A) enzyme 1. (B) enzyme 2. (C) enzyme 3. (D) both enzymes 1 and 3.
