Hydrogen pumps move hydrogen ions into which structure?
The thylakoid
What hydrogen ion pumps do?
also referred to as "Chemiosmotic Synthesis of ATP", hydrogen ions are removed from one side of the membrane to another. (inside to out), generating a proton gradient across the membrane. So we have a high concn of H+ ions outside the cell membrane. This causes the H+ ions in urgent need to get back inside with diffusion, thus protons move across membrane through special channels. Their passage drives the synthesis of ATP as well. btw this is also Active Transport. (ATP from cell is required).
What can be done to an ionic solid so that the ions are capable of motion?
The ionic solid needs to be melted or dissolved in a liquid to allow the ions to move freely. This breaks the rigid crystal lattice structure of the solid, allowing the ions to move around. Heating the solid to high temperatures can also provide the energy needed for the ions to move.
What happens to hydrogen at 20 degree's?
At 20 degrees Celsius, hydrogen remains a gas as it has a boiling point of around -253 degrees Celsius. At this temperature, hydrogen molecules continue to move independently and do not form any distinct structure.
Why does Hydrogen Chloride not conduct electricity when dissolved in hexane but conducts electicity when dissolved in water?
Water is a polar molecule and hexane is non-polar. This means that water has positive charges that grab on to the negative-chlorine and water has negative charges that grab onto the positive-hydrogen. This pulls the hydrogen and chlorine apart as positive and negative ions. The these positive and negative ions can move around separately as positive and negative electrical carriers. In hexane the hydrogen and chlorine are locked together, a single neutral molecule and no charged ions. Any positive movement of the hydrogen is locked to the negative movement of the chlorine, so any movement balances out to zero charge movement and zero electrical movement.
Hydrogen pumps move hydrogen ions into which structure?
The thylakoid
Which substances are transported across the cell membrane by ATP requiring transport pumps?
Substances such as ions like sodium, potassium, calcium, and hydrogen are transported across the cell membrane by ATP requiring transport pumps. These pumps consume ATP energy to move ions against their concentration gradient.
Membrane proteins called pumps use energy to move hydrogen ions to one side of the membrane. Which term describes the difference between the numbers of hydrogen ions on opposite sides of the membrane?
The term that describes the difference in the number of hydrogen ions on opposite sides of the membrane is "proton gradient." This gradient is a form of electrochemical gradient that results from the active transport of hydrogen ions (protons) by pumps, creating a difference in concentration and charge across the membrane. This gradient is essential for various cellular processes, including ATP production through chemiosmosis.
How do sodium potassium pumps work to maintain the balance of ions within cells?
Sodium-potassium pumps use energy to move sodium ions out of cells and potassium ions into cells, helping to maintain the balance of ions. This process is crucial for cell function and overall health.
What is the function of the proton pumps in the thylakoid membranes?
Proton pumps in the thylakoid membranes of chloroplasts create a proton gradient by pumping H+ ions from the stroma into the thylakoid lumen during photosynthesis. This gradient is utilized by ATP synthase to produce ATP through chemiosmosis.
Hydrogen ions move from the outer to the inner compartment of the mitochondria through what molecule?
Hydrogen ions move from the outer to the inner compartment of the mitochondria through the enzyme ATP synthase, which is embedded in the inner membrane. This movement of hydrogen ions creates an electrochemical gradient that drives ATP production.

What is used to move sodium ions?
Sodium ions are moved across cell membranes through the action of sodium-potassium pumps. These pumps use energy from ATP to transport sodium ions out of cells against their concentration gradient. Sodium ions can also pass through ion channels in the membrane via passive diffusion.
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.
Why does hydrogen iodide in an aqueous solution conduct an electricity?
Hydrogen iodide is dissociated in water.
Does hydrogen ions conduct electricity?
Yes, hydrogen ions (H+) can conduct electricity because they are charged particles that can carry an electric current. When dissolved in water, hydrogen ions can move and carry electrical charge, making them electrolytes that contribute to the conductivity of the solution.
Why is hydrogen peroxide a good conductor for electricity?
Hydrogen peroxide is a good conductor of electricity because it contains ions that can move freely, allowing electric current to flow through it. The presence of these ions in the solution makes hydrogen peroxide able to conduct electricity.
