The role of NAD in the citric acid cycle is the same as it was in glycolysis; namely, to "harvest" or "extract the energy from glucose. What additional molecule helps with this process in the citric acid cycle?
What, specifically, is being harvested by NAD and this other molecule?

it should be briana that has it to me

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers

hope it ,
