参考答案:
The
synthesis of complex molecules from simple molecules does involve a decrease in
entropy of the constituent molecules, since they have become more “structured”
or “ordered”. However, the molecules are
not a closed system. This process does
not occur spontaneously or in isolation.
The living organism in which the synthesis process occurs is part of the
environment that must be considered for the overall change in entropy. The living organism will have an increase in
entropy that is larger than the decrease in entropy of the molecules, and so
overall, the second law is still satisfied, and the entropy of the entire
system will increase.
