If Hydrogen ion concentration in the intermembrane space and the matrix reach equilibrium?
If hydrogen ion concentration in the inter membrane space and matrix of a mitocondria reach equilibrium then ATP synthase, which relies on a high concentration of hydrogen ions in the intermembrane space will work slower, letting less hydrogen ions into the matrix, while proteins in the electron transport chain pump hydrogen ions into the intermembrane space at a faster rate, destroying the equilibrium.
What else can I help you with?
Which ion ends up in the intermembrane space during electron transport chain?
Protons (H+ ions) end up in the intermembrane space during the electron transport chain. These protons are pumped across the inner mitochondrial membrane from the matrix to the intermembrane space as electrons flow through the electron transport chain.
When electrons are transported to enzyme complex 1 where is a proton transported?
Proton transport occurs in Complex I of the electron transport chain within the mitochondria. As electrons move through the complex, protons are pumped from the mitochondrial matrix into the intermembrane space, creating a proton gradient that drives ATP synthesis.
What involves diffusion of hydrogen ions to make ATP?
High concentration of H+ ion in the intermembrane lead to the movement of H+ ions into the inner membrane
Is kevlar a hydrogen bond?
No, Kevlar is not a hydrogen bond. Kevlar is a synthetic fiber made of a strong, heat-resistant polymer matrix. Hydrogen bonds are weak electrostatic interactions between hydrogen atoms and electronegative atoms like oxygen or nitrogen.
What cellular compartment becomes acidic during mitochondrial electron transport?
The mitochondrial intermembrane space becomes acidic during mitochondrial electron transport due to the pumping of protons from the matrix across the inner membrane to the intermembrane space by complexes I, III, and IV of the electron transport chain. This forms an electrochemical gradient used to generate ATP through ATP synthase.
What are the directions of hydrogen flow during synthesis of ATP?
During the synthesis of ATP, the flow of hydrogen ions (protons) is from the intermembrane space through the ATP synthase complex into the mitochondrial matrix. This movement of hydrogen ions creates a proton gradient that drives the synthesis of ATP from ADP and inorganic phosphate.
What stage of aerobic cellular respiration pumps hydrogen into the intermembrane compartment?
The stage of aerobic cellular respiration that pumps hydrogen ions into the intermembrane compartment is the electron transport chain (ETC). During this stage, electrons are transferred through a series of protein complexes, leading to the active transport of hydrogen ions from the mitochondrial matrix into the intermembrane space. This creates a proton gradient, which is essential for ATP synthesis during chemiosmosis.
How does the electron transport chain active during the Krebs cycle affect the hydrogen ion concentration in a mitochondrion?
During the Krebs cycle, the electron transport chain (ETC) actively pumps hydrogen ions (H⁺) from the mitochondrial matrix into the intermembrane space. This process creates a proton gradient, as the concentration of H⁺ ions becomes higher outside the matrix compared to inside. This electrochemical gradient is crucial for ATP synthesis, as H⁺ ions flow back into the matrix through ATP synthase, driving the production of ATP. Thus, the ETC indirectly regulates hydrogen ion concentration, contributing to the overall energy production in the mitochondrion.
Which type of cell transport is used by mitochondria to make hydrogen ions move against their concentration gradient?
Mitochondria utilize active transport to move hydrogen ions (protons) against their concentration gradient. This process primarily occurs during oxidative phosphorylation, where the electron transport chain pumps protons from the mitochondrial matrix into the intermembrane space. This creates a proton gradient, which is subsequently used by ATP synthase to generate ATP as protons flow back into the matrix.
What portion of the mitochondria has the lowest pH?
According to another answer to a similar question here on this site, "The intermembrane space has the lowest pH, highest concentration of H+, due to the gradient created by the electron transport chain."
What charge builds up in the matrix?
In the context of a mitochondrion, the matrix builds up a negative charge relative to the intermembrane space during the process of oxidative phosphorylation. This occurs as protons (H⁺ ions) are pumped from the matrix into the intermembrane space, creating a proton gradient. This electrochemical gradient contributes to the potential energy used by ATP synthase to produce ATP as protons flow back into the matrix. Thus, the matrix becomes increasingly negatively charged compared to the positively charged intermembrane space.
Where does the first electron carrier pump hydrogen ions?
The first electron carrier that pumps hydrogen ions during cellular respiration is NADH dehydrogenase (complex I) in the electron transport chain. It pumps hydrogen ions across the inner mitochondrial membrane from the matrix to the intermembrane space.
Where is hydrogen actively pumped in the mitochondria?
In mitochondria, hydrogen ions (protons) are actively pumped into the intermembrane space from the mitochondrial matrix during the electron transport chain process. This occurs primarily through the action of complexes I, III, and IV, which utilize the energy released from electron transfers to move protons across the inner mitochondrial membrane. The accumulation of protons in the intermembrane space creates a proton gradient, which drives ATP synthesis through ATP synthase as protons flow back into the matrix.
What causes an area of the inner membrane to become positively charged?
An area of the inner mitochondrial membrane becomes positively charged as a result of the electron transport chain process during cellular respiration. During this process, protons are pumped across the inner membrane, creating an electrochemical gradient with a higher concentration of protons in the intermembrane space compared to the mitochondrial matrix. This results in a positively charged intermembrane space and a negatively charged matrix.
Which ion ends up in the intermembrane space during electron transport chain?
Protons (H+ ions) end up in the intermembrane space during the electron transport chain. These protons are pumped across the inner mitochondrial membrane from the matrix to the intermembrane space as electrons flow through the electron transport chain.
What hydrogen pumps move hydrogen ions into which structure?
Hydrogen ions (protons) are primarily moved into the mitochondria by the proton pumps of the electron transport chain, specifically complexes I, III, and IV. These pumps transport protons from the mitochondrial matrix into the intermembrane space, creating a proton gradient. This gradient is essential for ATP synthesis, as protons flow back into the matrix through ATP synthase, driving the conversion of ADP to ATP.
How is the proton concentration gradient created inside and outside of mitochondrial inner membrane?
The proton concentration gradient across the mitochondrial inner membrane is created by the electron transport chain (ETC) during oxidative phosphorylation. As electrons are transferred through the ETC, energy released from these reactions is used to pump protons (H⁺) from the mitochondrial matrix into the intermembrane space, resulting in a higher concentration of protons outside the matrix. This creates a proton motive force, which is essential for ATP synthesis as protons flow back into the matrix through ATP synthase.
