What type of cell transport is used by chloroplasts to make hydrogen ions move against their concentration gradient?
Chloroplasts utilize active transport to move hydrogen ions against their concentration gradient. This process relies on energy, typically derived from ATP, to pump protons into the thylakoid lumen during photosynthesis. The resulting gradient of hydrogen ions is then used to drive ATP synthesis through chemiosmosis, ultimately supporting the production of energy-rich molecules.

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 happen when electrons are passed down the electrons transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
Do organisms always maintain the hydrogen ion concentration gradient?
No, organisms do not always maintain the hydrogen ion concentration gradient. Disruption of the hydrogen ion concentration gradient can occur due to factors such as illness, physical stress, or exposure to toxins, which can affect cellular processes and overall health.
What type of transport do the hydrogen ion pumps use?
Hydrogen ion pumps primarily use active transport to move hydrogen ions (H+) across a membrane against their concentration gradient. This process requires energy, typically derived from ATP hydrolysis or, in some cases, from the electrochemical gradient of other ions. Active transport allows these pumps to maintain specific ion concentrations essential for various cellular functions, including pH regulation and membrane potential.
What enzyme generates ATP using the concentration gradient of hydrogen ion?
ATP synthase is the enzyme that generates ATP using the concentration gradient of hydrogen ions. It is located in the inner mitochondrial membrane and uses the energy from the flow of hydrogen ions down their concentration gradient to convert ADP and inorganic phosphate into ATP.

What is formed when enzymes move hydrogen ions across a membrane to an area of greater concentration?
A proton gradient is formed when enzymes transport hydrogen ions across a membrane, creating a difference in concentration between the two sides. This gradient can then be used to drive other cellular processes such as ATP production or transport of molecules across the membrane.
What happens when sucrose is taken up by active transport?
Outside the cell is high concentration of hydrogen ions and low concentration of sucrose. Inside, is the opposite, low concentration of hydrogen ions, and high concentrations of sucrose. Cells use ATP to pump a hydrogen ion across the cell membrane, against the concentration gradient, and when the hydrogen ion goes to re-enter, it goes through a Sucrose-proton cotransporter. This means that the hydrogen ion (proton) take a sucrose molecule with it when it goes though the membrane.

What is the role of hydrogen ion gradient used for in cellular respiration in the mitochondria?
The hydrogen ion gradient is used to drive ATP synthesis. 32 to 34 molecules of ATP are produced. The hydrogen ion gradient is the result of NADH in the electron transport system of the mitochondria.
What is H plus concentration gradient?
The H+ concentration gradient refers to the difference in concentration of hydrogen ions (H+) across a membrane or barrier. This gradient can be used by cells to drive various processes such as ATP synthesis in mitochondria or neurotransmitter release in neurons. The movement of H+ ions down their concentration gradient can generate energy in the form of a proton motive force.
The proton gradient or the concentration of positive hydrogen ions in the stroma versus the concentration in the lumen is important because it powers the?
generation of ATP
Does the hydrogen serve as the final electron acceptor of the electron transport chain?
Oxygen is the final electron acceptor of the electron transfer chain. Hydrogen ( protons ) come down their concentration gradient and through the ATP sythase making ATP. Then they, with the electrons oxygen accepts, become H2O.
