What is the difference between Photophosphorylation and oxidative phosphorylation?
[tex] \mathfrak \blue{Answer :-}[/tex]
Photophosphorylation occurs in the chloroplast during photosynthesis, whereas oxidative phosphorylation occurs in mitochondria during cellular respiration. Both the processes synthesise ATP by chemiosmosis linked to the electron transport system.
In photophosphorylation, light energy is utilised for the production of a proton gradient, whereas in oxidative phosphorylation, the energy is derived from oxidation-reduction reactions, hence the respective names.
In photophosphorylation, accumulation of proton occurs in the lumen of the chloroplast, whereas in oxidative phosphorylation, accumulation of proton occurs in the intermembrane space of mitochondria.
Answer:
==>Oxidative phosphorylation occurs in mitochondria and converts chemical energy into ATP.
...
Differentiate between oxidative phosphorylation and photophosphorylation.
Points Oxidative phosphorylation Photophosphorylation
Energy Chemical energy is converted into ATP Light energy is converted into ATP.
Explanation:
==>Photophosphorylation occurs in the chloroplast during photosynthesis, whereas oxidative phosphorylation occurs in mitochondria during cellular respiration. Both the processes synthesise ATP by chemiosmosis linked to the electron transport system.
==>In photophosphorylation, light energy is utilised for the production of a proton gradient, whereas in oxidative phosphorylation, the energy is derived from oxidation-reduction reactions, hence the respective names.
==>In photophosphorylation, accumulation of proton occurs in the lumen of the chloroplast, whereas in oxidative phosphorylation, accumulation of proton occurs in the intermembrane space of mitochondria.
==>Photophosphorylation takes place in chloroplast during light reaction whereas oxidative phosphorylation takes place in mitochondria during respiration.
==>All green cells on illumination accomplish photophosphorylation whereas all living cells perform oxidative phosphorylation.
==>In photophosphorylation, energy stored in ATP is obtained by sun, whereas in oxidative phosphorylation, energy stored in ATP is obtained by oxidation of organic compounds.
==>Splitting of water occurs in photophosphorylation whereas synthesis of metabolic water occurs in this process.
==>Photophosphorylation produces reduced coenzymes, whereas oxidative phosphorylation oxidises reduced coenzymes.
