Living cells produce only one chiral form of a biomolecule because:
A) biomolecules, by definition, can exist as only one chiral form.
B) living cells can only create L isomers.
C) living cells choose to express only the correct isomer.
D) living cells have enzymes that are also chiral.
E) living cells can produce the opposite chiral form only under certain metabolic conditions.

Question

Quizplus · Accepted Answer

Living cells have enzymes that are chiral, which means they can only interact with substrates of a specific chirality. This specificity ensures that cells predominantly produce and utilize biomolecules of one chiral form, typically the L-form for amino acids and the D-form for sugars.
