Light Phase Flashcards
Where does the light phase take place?
In the grana
Where and by what is the radiant energy absorbed?
Absorbed by chlorophyll molecules and happens in thylakoids
What happens to the chlorophyll molecules after the light is absorbed?
Become activated and energised
radiant energy is transformed into what?
Chemical energy
What does the chlorophyll molecule lose?
An energy-rich electron
The energy-rich electron is passed along a chain called the?
The electron transfer system
What happens to the energy-rich electron when it losses energy
It makes ATP (Adenosine triphosphate)
What is the process of making ATP called
Photophosphorylation
Where does the chlorophyll molecule replace its lost electron from
From the H2O molecule (causing the H2O molecule to split into H2 + O2)
what is the splitting of H2O called
Photolysis
From the H2O that split into H2 + O2 : what happens to the O2 and H atom
O2 is BOOSTING to the atmosphere and H bonds with NADP to make NADPH
Radiant energy + O2(Into air) + H2O —> Energy rich H atmos + ATP —-> Dark phase
Just for understanding
ATP?
Energy carrier in all living cells
What is ATP Made of ?
1 adenosine molecule + 3 phsphate molecules
When cells need energy what happens to ATP
ATP Broken down into ADP —> phosphate molecule + energy
