LDR in Photosynthesis Flashcards
What is the first step of LDR?
Photolysis of water
What is Photolysis?
Breaking something using light energy
What does 2H2O get split into?
4H+, 4e- and O2
One by one, the _______ from the (4___) goes to the _________ _________ located in Photosystem II
Electron, e-, Reaction Center
What happens to the e- once it reaches the Reaction Center 2?
It gets a backpack full of energy
Where does the e- with the energy backpack travel through?
It travels through the Cytochromes
What is the road of the electron’s journey called?
Electron Transport Chain
What happens to the e- once it arrives at the Hydrogen Pump?
The energy backpack gets unloaded
What happens after the e- unloads the backpack?
It goes to the Reaction Center 1, located in Photosystem 1
During the electron’s journey, what happens to the H+ inside the membrane?
They pile up and start exiting the membrane
How does the H+ exit the membrane?
They leave through the ATP Synthase
What is the gushing flow of H+ through the ATP Synthase called?
Chemiosmosis
What does the H+ chain ultimately help?
It helps convert ADP into ATP
What is the process of going from ADP –> ATP called?
Phosphorylation
Is Chemiosmosis passive or active transport?
Passive
