The final electron acceptor at the end of the electron transport chain is resulting in formation of phosphate; atp coa; acetyl coa oxygen; water hydrogen; carbon dioxide

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
