What are the similarities between oxidative phosphorylation and photophosphorylation?
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.
Is photophosphorylation same as oxidative phosphorylation?
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.
What is photophosphorylation and oxidative phosphorylation?
Hint: Oxidative phosphorylation occurs in aerobic cells to generate energy through metabolism. Photophosphorylation is the process of capturing solar energy and converts to chemical energy. Complete answer: Both oxidative and photo-phosphorylation deals with generation of energy.
Why is oxidative phosphorylation important for humans?
Although oxidative phosphorylation is a vital part of metabolism, it produces reactive oxygen species such as superoxide and hydrogen peroxide, which lead to propagation of free radicals, damaging cells and contributing to disease and, possibly, aging and senescence.
Which of the following do phosphorylation 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 electrons provide energy to pump protons (H+) to one side of the membrane.
In what ways are oxidative phosphorylation and photophosphorylation similar quizlet?
Photosynthetic phosphorylation and oxidative phosphorylation appear to be generally similar processes, both consisting of ATP synthesis coupled to the transfer of electrons along an electron carrier chain.
What is photophosphorylation most similar to?
In mechanism, photophosphorylation is most similar to 1 substrate-level phosphorylation in glycolysis.
Which of the following do Photophosphorylation and oxidative phosphorylation have in common?
In what ways are oxidative phosphorylation and Photophosphorylation similar quizlet?
What two processes are coupled throughout the ETC that together make up oxidative phosphorylation?
Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient.
What do you understand by oxidative phosphorylation?
: the synthesis of ATP by phosphorylation of ADP for which energy is obtained by electron transport and which takes place in the mitochondria during aerobic respiration.
What is Photophosphorylation most similar to?
How is oxidative phosphorylation dependent on light?
Oxidative phosphorylation involves the reduction of O 2 to H 2O with electrons donated by NADH and FADH 2, and occurs equally well in light or darkness. Photophosphorylation involves the oxidation of H 2O to O 2, with NADP + as electron acceptor, and it is absolutely dependent on light.
Which is the electron acceptor in photophosphorylation?
Photophosphorylation involves the oxidation of H 2 O to O 2, with NADP + as electron acceptor, and it is absolutely dependent on light. These two highly efficient energy-conserving processes occur by fundamentally similar mechanisms.
How does splitting of water occur in photophosphorylation?
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.
How does energy transformation take place in photophosphorylation?
Energy transformation via photophosphorylation need not involve linear electron flow from an initial donor to a terminal acceptor. Instead, electrons can be repeatedly energized and cycled through an ETC in a process called cyclic photophosphorylation.
