Describe two different ways in which ATP is generated in cellular respiration.
Daniel Arnon and coworkers carried out experiments with intact, salt- washed chloroplasts to study photophosphorylation. When the chloroplasts were illuminated in the presence of ADP +P, ATP was produced, but oxygen was not produced or nor consumed. ATP formation was not accom- panied by a measurable electron transport involving any external electron donor or acceptor. The overall reaction for this result is: ADP + P -", ATP When NADP+ was included in addition to the ADP + P, ilumination of the intact chloroplats again resulted in resulted in the photophosphorylation of ADP to ATP. In addition, the NADPpt was reduced to NADPH + H* and o, was produced. Moreover, the light-induced reduction of NADP* was greatly decreased if ADP + P; were ommitted. The equation for this reaction is: NADP* + H,0 + ADP + R -", NADPH + H + ATP + }02 Briefly describe the mechanism(s) of these two types of photophosphoryla- tion that explain all of these results.
