The electron transport chain activity takes place in the inner membrane and the space between the inner and outer membrane, called the intermembrane space.

Where does mitochondrial ETC occur?
mitochondrion
The ETC is embedded within the extensive inner membrane of the mitochondrion, in close proximity to the mitochondrial matrix in which the TCA cycle is localized (Fig. 1).
Where do electrons take place?
Where Are Electrons? Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
Where does cellular respiration take place?
the mitochondria
Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).
Where is the ETC in the chloroplast?
ETC in chloroplasts takes place in the thylakoid membrane of the chloroplast.
How do electrons move?
The electrons move from negatively charged parts to positively charged ones. The negatively charged pieces of any circuit have extra electrons, while the positively charged pieces want more electrons. The electrons then jump from one area to another. When the electrons move, the current can flow through the system.
Where are electrons found in the atom apex?
The protons and neutrons are found in the middle of the atom in the nucleus. Meanwhile, the electrons are found on the outer shell of the atom.
How do electrons stay in orbit?
Simply electrons always revolve around the nucleus due to the electrostatic force between electron and nucleus,which creates a centripetal and a tangential acceleration in an electron. Due to the tangential acceleration the electron revolve around the nucleus.
Where and how does respiration take place?
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.
Where does glycolysis take place?
the cytoplasm
Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Where does photosynthesis take place?
chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
What is the function of etc?
Explanation: The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.
Where do the electrons in the ETC go at the end of photosystem II *?
The electrons are used to pump the hydrogen ions across the membrane, and are transferred through the Electron Transport Chain to Photosystem I. The final fate of the hydrogen ions is to power up ATP synthesis, and the final fate of the electrons is to be placed on a carrier molecule NADPH.
What is the structure of the ETC?
The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.
Why do electrons flow to earth?
The ground is an attractive place for electricity to flow because it is positively charged, only more so when the tiny particles in the atmosphere collide, filling clouds with negatively charged particles. (These are also called ions.)
Where do the electrons come from in electricity?
No electrons are created or destroyed. They come from the windings of the generator and the wires the electricity flows through. A metal has chemical bonds often described as a “sea of electrons” – they can move from atom to atom with little resistance and little change to the properties of the metal.
Do electrons move or vibrate?
Because an electron is a quantum object with wave-like properties, it must always be vibrating at some frequency.Furthermore, an electron in a stable atomic state does not move in the sense of waving through space. The orbital electron does move in the sense of vibrating in time.
Where are electrons found in an atom Brainly?
Explanation: electron is found in an atom in outside the nucleus of the atom.
Does electron actually spin?
Much to their surprise, however, the two physicists found that electrons themselves act as if they are spinning very rapidly, producing tiny magnetic fields independent of those from their orbital motions. Soon the terminology ‘spin’ was used to describe this apparent rotation of subatomic particles.
Why electron does not jump into the nucleus?
An electron will only react with a proton in the nucleus via electron capture if there are too many protons in the nucleus.But most atoms do not have too many protons, so there is nothing for the electron to interact with. As a result, each electron in a stable atom remains in its spread-out wavefunction shape.
Are electrons located in the cloud?
Where the cloud is most dense, the probability of finding the electron is greatest; and where the electron is less likely to be, the cloud is less dense. These dense regions are known as “electron orbitals”, since they are the most likely location where an orbiting electron will be found.
