Place numbers beside the statements below to indicate the order of events occurring in the light reactions.   I know for sure that 1 and 8 are correct, but the rest I’m not too confident about. I attached both my work and a blank copy.

Which one of the following is false about the ATP molecule? it's waste, ADP and P, can be recycled it powers many cellular proceses It contains three phosphate atoms it is a stable but usable form of cellular potential energy O it is fragile and falls apart easy It it can be made by mitochondria

You have isolated a bacterium which is a strict, obligate aerobe. You expose the bacterium to oxidative phosphorylation uncouplers. What will first happen to the bacterium, if anything? O electron transport by the ETC will stop O nothing will happen to the bacterium O the proton gradient will be diminished thus reducing ATP synthesis O proton pumping will stop

Which of the following regarding the Electron Transport Chain is INCORRECT? It can accept electrons from the Glycerol 3-Phosphate Shuttle It sets up the proton motive force Free energy from the exergonic electron flow is coupled to the endergonic transport of protons out of the matrix Electrons flow through electron acceptors/donors from a high reduction potential to a lower reduction potential

The purpose of ATP and compounds similar to ATP is to be available to catalyze the combustion of glucose serve as template for molecular replication oxidize chlorophyll store energy in P-O bonds
