CH 5: Quiz on Photosynthesis Flashcards
Is the creation of NADPH oxidized or reduced in the photosynthesis process?
Reduced
Where is the light-dependent reaction occurring in the chloroplast?
It happens in the photosystems I and II.
What happens to the H+ from photolysis?
Through the use of electrons and a protein, it enters the thylakoid with a substantial H+ concentration.
How is ATP made? what is the process called?
It is made in the ATP synthase through the passive transport of H+ ions in a process of chemiosmosis.
What is a Thylakoid Lumen
The area inside of a thylakoid disk.
What is the outermost membrane of a chloroplast cell called?
Outer Membrane
What is the inner membrane of a chloroplast cell called?
Inner membrane
What is a singular round thing in a chloroplast cell called?
Thylakoid
What are multiple round things in a chloroplast cell called?
Granum.
What is the space inside of a chloroplast cell called?
Stroma
What is the first step of the light dependent reactions of Photosynthesis?
- Electron splits from water molecule
- Electron carrier carries it into photosystem II
- At reaction center the electron gets excited with light energy
- Electron carrier carries it to electron acceptor
What is the second step of the light dependent reactions of Photosynthesis?
- Electrons go through the electron transport system
- Some electron energy is used into light independent reactions (Chemiosmosis, helping transportation of H+ to thylakoid)
What is the third step of the light dependent reactions of Photosynthesis?
- Electron carrier carries it to the photosytem I
- Electron gets excited by light energy at the reaction centre
- Electron carrier carries it to electron acceptor
What is the fourth step of the light dependent reactions of Photosynthesis?
- Electron transport system caries it to help in the creation of NADPH
NADP+ + H+ = NADPH
What is Reducing power? Give two examples.
Molecules that contain a large amount of available energy
Glucose and NADPH
