What happens to the extra energy in excited electrons as they pass along an electron trandsport chain in a chloroplast?
The extra energy in the excited electrons is used to pump hydrogen ions across the thylakoid membrane, creating a proton gradient. This gradient is then used to drive ATP synthesis during the process of chemiosmosis, providing energy for cellular activities.
What Series of electron acceptors in the thylakoid membrane remove energy from excited electrons to produce ATP?
The series of electron acceptors in the thylakoid membrane that remove energy from excited electrons to produce ATP is known as the electron transport chain (ETC). As electrons move through the ETC, their energy is used to pump protons across the membrane, creating a proton gradient. This gradient drives ATP synthesis through ATP synthase.
Where does a pair of electrons reaches the second electron carrier enough energy has been released to pump a proton from the stroma?
The pair of electrons reaches the cytochrome complex, where energy is released. This energy is used to pump a proton from the stroma into the thylakoid space against a concentration gradient, contributing to the proton gradient that drives ATP synthesis during photosynthesis.
How is gradient of ions maintained in the mitochondria?
By the action of electrons going down the electron transfer chain the energy is provided to pump H + into the outer lumen of the mitochondria creating the concentration gradient for H + to come down it's concentration gradient through the ATP synthase.
Series of electron acceptors in the thylakoid membrane that removes energy from excited electrons to produce ATP?
The series of electron acceptors in the thylakoid membrane is known as the electron transport chain. As electrons move through the chain, they lose energy, which is used to pump protons across the membrane, creating a proton gradient. This gradient is then used by ATP synthase to produce ATP through a process known as chemiosmosis.

Proton pump channels are used to make ADP from ATP during chemiosmosis?
Proton pump channels are actually used to create a proton gradient across a membrane during chemiosmosis. This gradient drives the enzyme ATP synthase to convert ADP and inorganic phosphate into ATP.
What event contributes directly to the creation of a proton gradient across the thylakoid membrane?
The flow of electrons through the photosynthetic electron transport chain contributes directly to the creation of a proton gradient across the thylakoid membrane. As electrons move through the chain, they pump protons from the stroma into the thylakoid lumen, generating the proton gradient used for ATP production during photosynthesis.
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.
The energy given up by electrons as they move through the electron transport chain is used to?
The energy given up by electrons as they move through the electron transport chain is used to pump protons across the inner mitochondrial membrane, creating a proton gradient. This proton gradient is then used to drive ATP synthesis by ATP synthase, producing ATP, the main energy currency of the cell.
What is the energy given up by electrons as they move through the electron transport chain used for?
The energy given up by electrons as they move through the electron transport chain is used to pump protons across the inner mitochondrial membrane to establish a proton gradient. This gradient is used by ATP synthase to generate ATP through a process called oxidative phosphorylation.
What releases energy that is used to pump hydrogen ions from the stroma into the thylakoid compartment?
The flow of electrons through the photosystems during photosynthesis releases energy that is used to pump hydrogen ions from the stroma into the thylakoid compartment. This process is driven by the transfer of energy-rich electrons from photosystem II to photosystem I, creating a proton gradient that is essential for ATP production in the light reactions of photosynthesis.
What Happens when electrons are passed down electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
