3. Which of the following statements about biological reactions is true?
a) There is enzyme for each and every biological reaction.
b) All biological reactions need to be coupled to exergonic reactions.
c) The standard free energies of reactions are always negative.
d) The free energy released during ATP hydrolysis depends on temperature.
.
5. A protein domain
a) cannot have beta sheets.
b) can fold only in the presence of the rest of the protein.
c) is always composed of multiple peptides.
d) can be disordered.
Homework Answers
3 d ) The free energy released during ATP hydrolysis depends on temperature.
every biological reaction does not have an enzyme, standard free energies of a reaction are not always negative because some reaction are non spontaneous ( positive ) , all the biological reaction does not need to be coupled to exergonic reaction.
5 d ) can be disordered
domain have a definite tertiary structure and function. they are folded independently of the rest of the protein.

Consider these hypothetical chemical reactions: A⇌B,ΔG= 13.7 kJ/mol B⇌C,ΔG= -27.2 kJ/mol C⇌D,ΔG= 6.20 kJ/mol What is the free energy, ΔG, for the overall reaction, A⇌D? Express your answer with the appropriate units. ΔG = Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions...
