8 Questions
What are the products of the enzyme action on water molecules in the thylakoid?
two electrons, two hydrogen ions H+, and one oxygen atom (O)
What happens to the charge across the thylakoid membrane as a result of the enzyme action on water molecules?
a charge separation is built up across the membrane
What is the role of the electrons from water in the electron transport chain?
replace the high-energy electrons that chlorophyll lost
Which proteins in the electron transport chain use energy from the electrons to pump H+ ions?
proteins in the chain
What is the final electron acceptor at the end of the second electron transport chain?
NADP+
What is the function of the proteins in the electron transport chain?
The proteins in the electron transport chain use energy from the electrons to pump H+ ions.
What is the role of chlorophyll in the electron transport chain?
Chlorophyll loses high-energy electrons that are replaced by the electrons from water in the electron transport chain.
What is the role of NADP+ in the electron transport chain?
NADP+ acts as an electron carrier and picks up high-energy electrons, along with H+ ions, at the outer surface of the thylakoid membrane.
Test your knowledge on the role of enzymes in the thylakoid membrane and the process of charge separation during photosynthesis. Explore how water molecules are broken down into electrons, hydrogen ions, and oxygen atoms, and understand the importance of this process in replacing high-energy electrons.
