What's the difference between Cellular Respiration and Photosynthesis

The earliest cells, prokaryotes living in an early Earth devoid of free oxygen, used various alternative electron acceptors to carry on anaerobic cellular respiration. After cyanobacteria invented oxygenic photosynthesis and pumped oxygen gas into the oceans and atmosphere, bacteria that adapted their electron transport chains to exploit oxygen as the terminal electron acceptor gained higher energy yield and thus a competitive advantage. One line of aerobic bacteria took up an endosymbiotic relationship within a larger host cell, providing ATP in exchange for organic molecules. The endosymbiont was the evolutionary ancestor of mitochondria. This endosymbiosis must have occurred in the ancestor of all eukaryotes, because all existing eukaryotes have mitochondria (Martin and Mentel, 2010). The evidence for the endosymbiont origin of mitochondria can be found in:

It takes place in the mitochondria, consuming oxygen, producing carbon dioxide and water as waste products, and converting ADP to energy-rich ATP.
Two Types of Fermentation
Lactic Acid Fermentation:
The process by which our muscle cells deal with pyruvate during anaerobic respiration.
Alcoholic Fermentation:
A type of cellular respiration which does not require oxygen (anaerobic respiration), and involves the breaking down of glucose to pyruvic acid and then finally ethanol.
Alcoholic Fermentation
Lactic Acid Fermentation:
Electron Transport

Definition of the Electron Transport Chain:
A group of compounds that pass electrons from one to another coupled with the transfer of protons across a membrane to create a proton gradient that drives ATP synthesis.
Inner mitochondrial membrane
How do you inputs and outputs of photosynthesis relate to those of respiration?
The inputs and outputs of photosynthesis relate to those of respiration because the outputs of photosynthesis (oxygen, glucose, and water) are the inputs of respiration.

Comparing chemiosmosis in cell respiration & photosynthesis

Photosynthesis and cellular respiration are similar in that they both undergo chemiosmosis
