What type of phosphorylation occurs in chloroplast?
11.3. 4 Phosphorylation. In eukaryotes, oxidative phosphorylation occurs in mitochondria, while photophosphorylation occurs in chloroplasts to produce ATP.
Where does non-cyclic photophosphorylation occur in chloroplast?
granal thylakoid region
Complete answer: Non-cyclic phosphorylation takes place in the granal thylakoid region of chloroplast.
Where does photophosphorylation occur in the chloroplast?
Photophosphorylation is the light-dependent reaction, which occurs in the chloroplasts of the plant cells, specifically, in the thylakoid membranes.
What is non photosynthetic photophosphorylation?
The pigment is a type of rhodopsin called bacteriorhodopsin which reacts with light in a way that forms a proton gradient on the membrane allowing the synthesis of ATP. This is the only example in nature of non photosynthetic photophosphorylation. These organisms are heterotrophs that normally respire by aerobic means.
Is chlorophyll The only light absorbing pigment in chloroplast?
Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
What is non-cyclic phosphorylation?
Non-cyclic Photophosphorylation. The photophosphorylation process which results in the movement of the electrons in a non-cyclic manner for synthesizing ATP molecules using the energy from excited electrons provided by photosystem II is called non-cyclic photophosphorylation.
What part of chloroplast does light reaction occur?
The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.
What do the light-dependent reactions of photosynthesis produce?
2. The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.
Does oxidative phosphorylation occur in photosynthesis?
Oxidative phosphorylation occurs during cellular respiration. Photophosphorylation occurs during photosynthesis.
Are light reactions Endergonic or Exergonic?
The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.
What light does chlorophyll absorb?
Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.
