lukranit [14]
1) Both involve electron transport chains. 
<span>2) Chemiomosis allows ATP synthase to produce ATP. </span>
<span>3) Both take place at some point within an organelle (mit. = CR, chloroplast= photo.) </span>
<span>4) Both utilize ATP for energy at some points. </span>
<span>5) Both provide power for cellular activities. </span>
<span>5 Differences </span>
<span>1)Cellular respiration depends on oxygen as a substrate. </span>
<span>2)Photosythesis utilizes 2 electron transport chains (not just 1). </span>
<span>3)In Photo. , energy is provided by photons and not catabolic processes as in cell. resp. </span>
