Is hydrogen gradient across the mitochondrial inner membrane a cellular energy currency?
ATP molecules are essentially cellular energy currency. The hydrogen gradient (or proton gradient as it is technically called) is responsible for the functioning of a protein complex called ATP synthase which in turn is responsible for the synthesis of ATP molecules. Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.

What is the hydrogen ion gradient maintained by?
The hydrogen ion gradient is maintained by the electron transport chain during cellular respiration. This process uses the energy from electrons to pump hydrogen ions across the inner mitochondrial membrane, establishing a gradient that drives the production of ATP through ATP synthase.
What is the energy of the hydrogen ion gradient created across the inner mitochondrial membrane used to make?
electron transport chain
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 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.
Hydrogen pumps move hydrogen ions into which structure apex?
Hydrogen pumps move hydrogen ions into the thylakoid lumen of chloroplasts during the process of photosynthesis. This creates a proton gradient across the thylakoid membrane, which is essential for ATP synthesis. In cellular respiration, similar proton pumps are found in the inner mitochondrial membrane, contributing to the generation of ATP through oxidative phosphorylation.

What is the enzyme that acts as a motor - generating the energy currency of the cell?
The enzyme that acts as a motor and generates the energy currency of the cell is ATP synthase. It is responsible for synthesizing adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate (Pi) using the energy generated by the hydrogen ion gradient across the inner mitochondrial membrane during cellular respiration.

Which molecules are responsible for creating a chemiosmotic gradient?
Protons (H+) are the main molecules responsible for creating a chemiosmotic gradient across biological membranes. In cellular respiration, the electron transport chain pumps protons across the inner mitochondrial membrane, creating a gradient that drives ATP synthesis through ATP synthase.
What is the energy of hydrogen ion gradient created across the inner mitochondrial membrane used to make?
The hydrogen falls down its electrochemical gradient, from an area of high concentration to an area of lower concentration, through the ATP synthase and provides the force to power this synthase and synthesize ATP.

What does Chemiosmosis involves .?
The movement of hydrogen ions across a mitochondrial membrane.
When hydrogen ions are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space the result is?
Hydrogen ions are pumped through the membrane in the final stage of ATP generation in the electron transport chain. The ions pumped through the membrane create a gradient and cause the hydrogen to "want" to pass back through the membrane. They do so through the protein channels in the membrane and attaches a phosphate to adenosine diphosphate to make adenosine triphosphate.
What is chemiosis?
Chemiosis, also known as chemiosmosis, is a process that occurs during cellular respiration and photosynthesis. It involves the movement of ions across a membrane to generate ATP, the energy currency of the cell. Chemiosis relies on an electrochemical gradient to drive the production of ATP.
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.
