LIFESCI 2 Study Guide - Midterm Guide: Tight Junction, Collagen, Exergonic Reaction
Document Summary
[questions 1-2] the phosphorylation of a protein is not a spontaneous reaction. However, when that reaction is coupled to the hydrolysis of atp, the pair of reactions is spontaneous. For each of the statements below, mark a for true and b for false: the phosphorylation reaction alone is endergonic. A: the energy required for the phosphorylation reaction is less than the energy release during the hydrolysis of atp. [question 3] cellular respiration plays an important role in energy conversion for the cell. For the following statements, mark a for true and b for false: moving protons across a membrane where there is a higher concentration of h+ on the receiving side is an endergonic process. A: antinomycin a is a poison that affects the electron transport chain and renders it nonfunctional. In the presence of antinomycin the krebs cycle would. [questions 5-6] assume the redox potential of cyt-b were to change from +70 to -120.
