Which is the best description of phosphorylation?
Phosphorylation: A biochemical process that involves the addition of phosphate to an organic compound. Examples include the addition of phosphate to glucose to produce glucose monophosphate and the addition of phosphate to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP).
What is difference between photophosphorylation and oxidative phosphorylation?
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.
Which of the following do photophosphorylation and oxidative phosphorylation have in common?
The similarities of photophosphorylation to oxidative phosphorylation include: a membrane associated electron transport chain. creation of a proton gradient. harvesting energy of the proton gradient by making ATP with the help of an ATP synthase.
What do photosynthesis and oxidative phosphorylation have in common?
Both photophosphorylation and oxidative phosphorylation (oxphos) are processes cells use to make energy in the form of ATP. First the similarities: in both cases electrons are transferred through a series of membrane proteins. the protons flow back through a special enzyme (ATP-synthase) which makes ATP.
Which is the best description of Photophosphorylation quizlet?
Which statement best describes photophosphorylation? It is the addition of a phosphate group to ADP to form ATP using light energy absorbed during photosynthesis.
Which is the best description of Photophorylation?
Photophosphorylation is the process of transferring the energy from light into chemicals, particularly ATP.
What is phosphorylation in cellular 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 is phosphorylation similar to oxidative phosphorylation?
What are the similarities and differences between photophosphorylation and oxidative phosphorylation? Both processes operate on the same basic principle; passing electrons down a chain in order to create a proton (H+) gradient, allowing the formation of ATP. The biggest difference is where they occur.
Where does electron transport and oxidative phosphorylation occur?
mitochondria
What is oxidative phosphorylation? Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria (called the electron transport chain and ATP synthase) to create ATP.
Which of the following best describes chlorophyll?
Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.
What is the difference between oxidative phosphorylation and photophosphorylation?
Oxidative phosphorylation utilises molecular oxygen during the synthesis of ATP, and it takes place near the membranes of the mitochondria while photophosphorylation utilizes sunlight as the energy source for the production of ATP, and it takes place in the thylakoid membrane of the chloroplast.
How does photophosphorylation use light energy?
All forms of photophosphorylation use light energy to lower the potential, and thereby raise the energy, of electrons in the ETC.
Where does photophosphorylation take place in prokaryotic cells?
This takes place in the stroma of the chloroplast. When plants use light energy from photosynthesis to convert ADP to ATP, the process is known as photophosphorylation. In prokaryotes, the process of photosynthesis helps in the production of energy and not for the formation of biological molecules.
What is the difference between cyclic and non-cyclic photophosphorylation?
Following are the important differences between cyclic and non-cyclic photophosphorylation: Only Photosystem I is involved. Both Photosystem I and II are involved. P700 is the active reaction centre. P680 is the active reaction centre. Electrons travel in a cyclic manner.
