In the process of photosynthesis,
the phosphorylation of ADP to form ATP
using the energy of sunlight is called photophosphorylation. … All organisms produce ATP, which is the universal energy currency of life.
Is there oxidative phosphorylation in photosynthesis?
In oxidative phosphorylation, the
energy
comes from electrons produced by oxidation of biological molecules. In photosynthesis, the energy comes from the light of the sun. … The similarities of photophosphorylation
Does oxidative phosphorylation occur in photosynthesis?
Photophosphorylation
Does oxidative phosphorylation occur in plants?
Mitochondrial Oxidative Phosphorylation (OXPHOS) provides ATP for driving cellular functions. In plants,
OXPHOS takes place in the context of photosynthesis
. Indeed, metabolism of mitochondria and chloroplasts is tightly linked. OXPHOS has several extra functions in plants.
Where does phosphorylation take place in photosynthesis?
In eukaryotes, oxidative phosphorylation occurs in mitochondria, while photophosphorylation
Where does phosphorylation occur?
Oxidative phosphorylation takes place in
the inner mitochondrial membrane
, in contrast with most of the reactions of the citric acid cycle and fatty acid oxidation, which take place in the matrix.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons
return through ATP synthase
to make ATP.
What are the steps of oxidative phosphorylation?
The three major steps in oxidative phosphorylation are (a) oxidation-reduction reactions involving electron transfers between specialized proteins embedded in the inner mitochondrial membrane;
(b) the generation of a proton (H
+
) gradient across the inner mitochondrial membrane
(which occurs simultaneously with step (a …
What enzyme is used in oxidative phosphorylation?
ATP synthase, also called complex V
, is the final enzyme in the oxidative phosphorylation pathway. This enzyme is found in all forms of life and functions in the same way in both prokaryotes and eukaryotes.
What is the main function of oxidative phosphorylation?
Oxidative phosphorylation is the process in which
ATP is formed as a result of the transfer of electrons
What do photosynthesis and oxidative phosphorylation have in common?
Both photophosphorylation
Which statement is correct for photosynthesis?
The correct option is c. The
process of photosynthesis results in the evolution of oxygen
.
What is phosphorylation in respiration?
Oxidative phosphorylation is
the fourth step of cellular respiration
, and produces the most of the energy in cellular respiration. … Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP.
How does phosphorylation occur?
Usually, phosphorylation occurs
when DNA is damaged, opening up space around broken DNA
so that repair mechanisms can do their work. In addition to its importance in DNA repair, protein phosphorylation plays a key role in metabolism and signaling pathways.
