How does pH affect the concentration of ions in the mitochondria?
How does pH affect the concentration of ions in the mitochondria?
Hear this out loudPauseLow pH increases the concentration of base causing mitochondria to pump out H+ to the inter membrane space leading to ATP production. The high external acid concentration causes an increase in H+ in the inter membrane space leading to increased ATP production by ATP synthetase.
What happens to the H+ ion concentration in a mitochondrion?
Hear this out loudPauseThe high external acid concentration causes an increase in H+ in the inter membrane space leading to increased ATP production by ATP synthetase. Thus, placing mitochondria in a low pH buffer produces a H+ gradient that can generate ATP through ATP synthetase.
Where is the concentration of hydrogen ions greatest in the mitochondria?
intermembrane space
Hear this out loudPauseThe H+ concentration is highest in the intermembrane space of the mitochondria.
What effect can hydrogen ions have on the mitochondria?
Hear this out loudPauseHydrogen ions in the matrix space can only pass through the inner mitochondrial membrane through a membrane protein called ATP synthase. As protons move through ATP synthase, ADP is turned into ATP. The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation.
Where is pH lowest in mitochondria?
Hear this out loudPauseThis results in the intermembrane space having the lowest pH in the mitochondria, due to the high proton concentration.
What affects the pH of intermembrane space?
Hear this out loudPauseThe ETC pumps H+ ions out of the matrix into the intermembrane space. In addition to the potential, there is a concentration difference in H+ established across the membrane. The pH of the intermembrane space is about 7.0, whereas the pH of the matrix is about 8.0.
What would happen if the concentration of H+ ions are higher inside the mitochondria than outside?
Hear this out loudPauseAnswer: If the concentration of H ions were higher inside the mitochondrion than outside the mitochondrion then the H ions would move to outside the mitochondrion to equalize the pH of both inner and outer side through the opened channel.
What is the pH of the mitochondrial matrix?
about 7.8
Hear this out loudPauseMitochondrial matrix has a pH of about 7.8, which is higher than the pH of the intermembrane space of the mitochondria, which is around 7.0–7.4.
What is the pH of the intermembrane space?
about 7.0
Hear this out loudPauseThe pH of the intermembrane space is about 7.0, whereas the pH of the matrix is about 8.0.
What is the pH of cytosol?
between 7.0–7.4
Hear this out loudPauseMost of the cytosol is water, which makes up about 70% of the total volume of a typical cell. The pH of the intracellular fluid is 7.4. while human cytosolic pH ranges between 7.0–7.4, and is usually higher if a cell is growing.
What would happen if the concentration of H+ ions?
Hear this out loudPauseAnswer: A. H+ ions would not flow.
