Questions and Answers

In photosystem II, what causes the thylakoid space to become strongly positive with respect to the stroma?

Hydrogen ions (H+) accumulating within the thylakoid space.

What provides the energy to make ATP in the thylakoid membrane?

The difference in both charge and H+ ion concentration across the membrane (the gradient).

What protein complex allows H+ ions to pass through the thylakoid membrane?

ATP synthase.

How are H+ ions able to pass through ATP synthase?

<p>The H+ concentration difference across the membrane powers ATP synthase to rotate, allowing H+ ions to pass through.</p> Signup and view all the answers

What does ATP synthase bind together to produce ATP?

<p>ADP (adenosine diphosphate) and a phosphate group.</p> Signup and view all the answers

What is the role of hydrogen ions in the thylakoid space in photosystem II?

<p>Hydrogen ions accumulate in the thylakoid space and create a positive charge gradient that provides the energy to produce ATP.</p> Signup and view all the answers

How does the ATP synthase protein complex generate ATP in the thylakoid membrane?

<p>ATP synthase allows H+ ions to pass through it, powered by the H+ concentration difference. As it rotates, ATP synthase binds ADP and a phosphate group together to produce ATP.</p> Signup and view all the answers

What is the source of the hydrogen ions that accumulate in the thylakoid space?

<p>The hydrogen ions are left behind from the splitting of water at the end of the electron transport chain.</p> Signup and view all the answers
