Problem 41
Would you expect the reaction \(\mathrm{ATP} \rightarrow \mathrm{ADP}+\mathrm{P}_{\mathrm{i}}\) to be accompanied by a decrease or increase in entropy? Why?
Problem 42
The existence of organelles in eukaryotic cells represents a higher degree of organization than that found in prokaryotes. How does this affect the entropy of the Universe?
Problem 43
Why is it advantageous for a cell to have organelles? Discuss this concept from the standpoint of thermodynamics.
Problem 44
Which would you expect to have a higher entropy: DNA in its well-known double- helical form, or DNA with the strands separated?
Problem 50
In biochemistry, the exergonic process of converting glucose and oxygen to carbon dioxide and water in aerobic metabolism can be considered the reverse of photosynthesis, in which carbon dioxide and water are converted to glucose and oxygen. Do you expect both processes to be exergonic, both endergonic, or one exergonic and one endergonic? Why? Would you expect both processes to take place in the same way? Why?
