What goes in the electron transport chain?
When light hits photosytem II (within the thylakoid), it excites electrons which move through the electron transport chain.
The function of the electron transport proteins in the thyakoid membranes is?
The function of the electron transport proteins in the thylakoid membranes is to pump hydrogens into the thylakoid space for later generation of ATP. This process is called chemiosmosis.
What is the function of the proton pumps in the thylakoid membranes?
moving hydrogen nuclei out of the thylakoid
Where in the chloroplast is the H plus concentration highest?
The chloroplast is the hydrogen ion concentration is highest in the spaces of its thylakoid membrane. The ions get pushed into these spaces during the transportation of electrons.
Can hydrogen serve as the final electron acceptor of the electron transport chain?
No. Hydrogen's electronegativity is too weak. At 2.5 hydrogen does not have the electronegativity to pull electrons down the electron transport chain.

What releases energy that is used to pump hydrogen ions from the stroma into the thylakoid compartment?
The electron transport chain releases energy in order to pump protons (hydrogen ions) from the stroma into the thylakoid compartment, creating a proton gradient within the thylakoid membrane.
Where in the chloroplast is the H plus concentration highest?
The chloroplast is the hydrogen ion concentration is highest in the spaces of its thylakoid membrane. The ions get pushed into these spaces during the transportation of electrons.
How many electrons can a NADH molecule carry?
The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.
Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane results in the synthesis of ATP during light reaction. Thylakoid membranes contain proteins. These proteins make use of light energy to drive electron transport chains. This generates a chemiosmotic potential across the thylakoid membrane and NADPH. The ATP synthase enzyme uses the chemiosmotic potential to make ATP during photo- phosphorylation.
ATP is formed when the thylakoid compartment?
Hydrogen ion leaves the thylakoid lumen.
Can hydrogen serve as the final electron acceptor of the electron transport chain?
No. Hydrogen's electronegativity is too weak. At 2.5 hydrogen does not have the electronegativity to pull electrons down the electron transport chain.
The electrons of which element are the primary substance carried by the electron transport system?
hydrogen
Where do the electrons come from that are processed in the electron transport chain?
Hydrogen molecules of water
What is the final acceptor of the electrons and hydrogen's of the electron transport chain?
oxygen
