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
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 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 ions accumulate in the outer compartment of the mitochondria during electron transport phosphorylation?
Protons (H+) accumulate in the outer compartment of the mitochondria during electron transport phosphorylation. This forms an electrochemical gradient that drives ATP synthesis as protons flow back into the mitochondrial matrix through ATP synthase.
Which type of cell transport is used by mitochondria to generate energy by allowing hydrogen (H ) ions to flow through a membrane protein?
Mitochondria utilize facilitated diffusion to generate energy by allowing hydrogen ions (H⁺) to flow through a membrane protein known as ATP synthase. This process occurs during oxidative phosphorylation, where the flow of H⁺ ions down their concentration gradient drives the synthesis of ATP from ADP and inorganic phosphate. The movement of these ions is aided by the electrochemical gradient established by the electron transport chain.

Why mitochondrion is called powerhouse of the cell?
Mitochondria are the powerhouses of cells because they are the epicenter of the electron transport chain. While glycolysis can occur in the cytoplasm, the bulk of energy production takes place due to a hydrogen concentration gradient found in 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.

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.
Why are parietal cells acidophilic?
Parietal cells are acidophilic because they contain a large number of mitochondria. The mitochondria, which are needed to pump hydrogen ions against their concentration gradient, are acidophilic; therefore, parietal cells are acidophilic as well.
In what organelle does the electron transport chain function?
The electron transport chain converts energy stored in hydrogen ions and various other substances formed in early cellular respiration to produce high energy ATP in mitochondria. Mitochondria contain both an inner and an outer membrane, and it is along the inner membrane that the actual reactions of the chain occur. Inside the inner membrane a surplus of hydrogen ions is created that produces a concentration gradient across the membrane to the intermembrane space. This gradient causes a force that pushes hydrogen ions out of the innermost matrix and into the intermembrane space. This exchange occurs through special proteins called ATP synthase that convert low energy ADP into high energy ATP whenever a hydrogen ion is sent through one. When all is said and done, the excess electrons and hydrogen are bonded to oxygen to form water molecules.
