Describe the similarities and differences in chemiosmosis between oxidative phosphorylation in mitochondria and photophosphorylation in chloroplasts.

Expert Solution

Photophosphorylation take place in chloroplast

oxidative phosphorylation takes place in mitochondria during respiration

Similarities

Both processes are using for ATP Production

In both the processes eletrones passes through Series of membrane proteins .

Proton gradient is produced in one side of the membrane

. Proton moves through ATP synthase

. Differences

Photophosphorylation produces reduced coenzymes

oxidativephosphorylation oxidises reduced co enzymes

Oxidative Phosphorylation take during Cellular respiration

photophosphorylation occurs during photosynthesis

Ocidatyphosphorylation ccurs inside mitochondria

photophosphorylation occurs inside thylakoids

The energy source for oxidstve phosphorylation is glucose

the energy source for photophosphorylation sunlight

Splitting of water occurs in photophosphorylation whereas synthesis of metabolic water occurs in this process

.Photo phosphorylation ATP is obtained by sun , whereas in oxidative phosphorylation , energy stored in ATP is obtained by oxidation of organic compounds .

List three similarities and three differences between oxidative phosphorylation in the mitochondria and photophosphorylation in the chloroplast

Compare photophosphorylation, substrate level phosphorylation, and oxidative phosphorylation

Oxidative phosphorylation is a process that occurs in the _______________ of mitochondria.

Oxidative phosphorylation is a process that occurs in the _______________ of mitochondria. It requires an electron-transport chain that operates on the high-energy electrons taken from the activated carrier molecules+ _____________ and _______________ that are produced by glycolysis and the citric acid cycle. These electrons are transferred through a series of molecules, and the energy released during these transfers is used to generate a gradient of _____________. Since their concentration is much __________________ outside than inside the mitochondria, the flow of...

The first theories to explain the similarities between bacteria and mitochondria or chloroplasts suggested that an early eukaryotic cell actually engulfed but failed to fully digest a free-living prokaryotic cell. Why is such an event unlikely to account for the origin of mitochondria or chloroplasts?
