When scientists placed ATP Synthase linked to fluorsecent actin on a microscope slide and added ATP,the actin could be seen spinning counterclockwise.If the experiment could be replicated in a cell going through oxidative phosphorylation what would happen?
A)The actin would spin counterclockwise because ATP would be hydrolyzed.
B)The actin would spin clockwise because ATP would be produced instead of hydrolyzed.
C)The actin would spin counterclockwise because ATP would be produced instead of hydrolyzed.
D)The actin would spin clockwise because ATP would be hydrolyzeD.

CIn the cell, ATP synthase produces ATP from ADP and inorganic phosphate during oxidative phosphorylation, causing the actin to spin in the direction opposite to that observed when ATP is hydrolyzed. Thus, if ATP is being produced (as in oxidative phosphorylation), the direction of spin would be reversed from the experiment where ATP is hydrolyzed. Choices B and C correctly reflect the outcomes based on whether the actin spins clockwise or counterclockwise when ATP is produced.
