How many protons are pumped out of the matrix when 2 electrons flow through the ETC complex?
For every pair of electrons that flow through the electron transport chain (ETC) complex, it results in the pumping of 2 protons out of the matrix. This proton pumping contributes to the establishment of an electrochemical gradient across the inner mitochondrial membrane, which is utilized to generate ATP through ATP synthase.
What does not state a property of electricity?
It is a flow of protons
Why does current generally involve the flow of electrons but not protons?
The protons are bound inside the nucleus and are not free. In conductors, the electrons are free to move.
How do protons and electrons affect each other?
Protons don't really relate to electricity. Electron do because electricity is the flow of electrons through a wire. Protons don't really relate to electricity except in some nuclear physics applications. Electrons do because electricity, by definition, is the flow of electrons through a wire. In its most fundamental form, electricity is the movement of charged particles. Protons qualify because they are charged particles. We don't usually cause protons to "flow" like we commonly do electrons, though we do use them frequently in particle accelerators. But protons are not generally thought of as associated with "normal" electricity, which is usually considered to be the movement of electrons. It is the electron that is at the heart of electricity in the electronic world we live in. Wikipedia has all these facts and more. A link is provided.
Where are the electrons located?
The electrons flow around the atoms nucleus...the protons and neutrons are on the inside of the neucleus.
What event contributes directly to the creation of a proton gradient across the thylakoid membrane?
the flow of electrons through electron transport chain II
Which of the following best describes the direct mechanism of ATP production during photosynthesis?
Protons are pumped across the thylakoid membrane, where they flow back through ATP synthase which synthesizes ATP.
Are electricity the controlled flow of protons through a conductor?
The flow is of delocalized electrons.
Is Electricity is the controlled flow of protons through a conductor.?
No. Electrons.
What would describe a situation in which thylakoid is used in the production of atp?
ATP produced by noncyclic flow electrons in thylakoid membrane.
Trace the events that occur in the thylakoid membrane during the light-dependent reactions?
Electrons flow to NADP+, split water, pump protons (H+), and produce ATP.
Synthesis of ATP during the light reactions?
Hydrogen ions, flowing from the thylakoid lumen to the stroma in the chloroplast, have to move through a protein called the ATP synthase. Each time 3 protons moves through it, an ADP is phosphorylated into ATP. The protons move through the protein because a gradient is built up and there is a high concentration of protons in the lumen compared to that of the stroma. These protons move freely down their chemical gradient by chemiosmosis, and the ATP synthase takes advantage of this process by using their energy to power itself.
What is the effect of the flow of protons through the inner mitochondrial membrane?
energy is provided to make ATP
The flow of what particle across the thylakoid membrane powers the production of ATP?
Hydrogen Ions
Which type of ecological pyramid best traces the flow of matter through an ecosystem?
The trophic pyramid describes the flow of energy through a system from producers all the way up to predators. This is the best model because it follows the rule of ten.
