Which organelle produces ATP via electron transport system?
The electron transport chain (ETC) is conducted in the mitochondria. The four complexes of the ETC, along with the enzyme that produces ATP (known as Complex V, ATP synthase, or F0F1-ATPase), are located in the inner mitochondrial membrane.
What protein complex absorbs in energy that used to produce NADPH?
Photosystem 1
Where is the electron transport system found on the bacteria?
Since prokaryotic cells do not have complex organelles such as a nucleus or mitochondria as do their counterparts, the eukaryotic cells. The electron transport system (ETS) for bacteria is found on the inner membrane.
What is the end product of noncyclic photophosphorylation?
Cyclic photophosphorylation is the production of some ATP in the light dependent stage of photosynthesis. No photoylsis of water occurs and therefore no reduced NADP is produced either. Only photosystem one is involved here and as light is absorbed by the photosystem, two electrons are released which are accepted by the electron transfer chain. As the electrons are transferred along the chain, energy is released which pumps protons across the thylakoid membrane. A proton gradient forms and the protons diffuse through protein channels associated with ATP synthase enzymes, the proton motive force along with the enzyme combine ADP and inorganic phosphate atom to create ATP. The flow of protons which creates the ATP is chemiosmosis. The ATP can then be used in the light independent stage of photosynthesis or to actively transport potassium ions into the guard cells, so they become turgid as a result of water entering by osmosis. This causes the stomata to open and carbon dioxide can readily diffuse in - increasing the rate of photosynthesis.
What are photosystems made of?
In the thylakoid membrane a number of light-harvesting complexes and a reaction center complex. The chlorophyll a molecule at the reaction center of photosystem II is called P680. At the reaction center of photosystem I is a chlorophyll a molecule called P700.
What is Electron Transport Systems?
Proteins that invovled in electron transport chain in mitochondria are good examples. There are four different protein complexes transfer the electron from the frist complex to the terminal protein. Photosynthesis, photosystem II and photosystem I does the same job.
What are the products of a non-cyclic electron flow?
In photosynthesis, the noncyclic electron flow produces enzymes called cytochrome b6f complex. Its function is to catalyze the electron transfer of plastoquinol to plastocyanin.
Which organelle produces ATP via electron transport system?
The electron transport chain (ETC) is conducted in the mitochondria. The four complexes of the ETC, along with the enzyme that produces ATP (known as Complex V, ATP synthase, or F0F1-ATPase), are located in the inner mitochondrial membrane.
Is the energy from sunlight trapped by chlorophyll located in the electron transport chain?
No, the energy trapped by chlorophyll is located in photosystem I and II. Light energy is first captured by PS II and an electron is then transferred to a primary electron acceptor known as plastoquinone. Pq then transfers it's electron to the cytochrome complex that transfers its energy to the electron transport system which passes it on to plastocyanin which in turn gives its electron to PS I where it is re-excited by photons. This process is known as the electron transport but the energy captured by chlorophyll is located in the photosystems.
To which component of the electron transport chain does cyanide bind?
Cyanide binds the electron transport chain at the level of complex IV
Complex IV of the electron transport chain?
Directs electron to oxygen to form water
Which electron transport chain complex would be impaired by a deficiency of copper?
Complex IV
What happens after the reaction center receives energy from molecules in the light harvesting complex?
It passes the energy to the reaction center ( a specialized region of photosystem) then the energized electrons leave the reaction centers and are passed to adjacent electron transport chains (ETC)
Complex II of the electron transport chain?
includes a succinate dehydrogenase
Complex I of the electron transport chain?
is responsible for accepting electrons from NADH
What is composed of a light-harvesting complex and an electron transport system?
The chloroplast
What protein complex absorbs in energy that used to produce NADPH?
Photosystem 1
