Question

Quizplus · Accepted Answer

Scientists believe that using plant material for ethanol production will not become efficient until the ethanol can be made from cellulose instead of sugars and starches. While lignin and hemicellulose also make up plant material, they are not as abundant or as easily converted to ethanol as cellulose. Nucleic acids are not a component of plant material and therefore are not relevant to ethanol production. Therefore, choice A (cellulose) is the best answer.
