Q

What happens to the H+ from photolysis?

A

Q

How is ATP made? what is the process called?

A

It is made in the ATP synthase through the passive transport of H+ ions in a process of chemiosmosis.

Q

What is the first step of the light dependent reactions of Photosynthesis?

A
  1. Electron splits from water molecule
  2. Electron carrier carries it into photosystem II
  3. At reaction center the electron gets excited with light energy
  4. Electron carrier carries it to electron acceptor

Q

What is the second step of the light dependent reactions of Photosynthesis?

A
  1. Electrons go through the electron transport system
  2. Some electron energy is used into light independent reactions (Chemiosmosis, helping transportation of H+ to thylakoid)

Q

What is the third step of the light dependent reactions of Photosynthesis?

A
  1. Electron carrier carries it to the photosytem I
  2. Electron gets excited by light energy at the reaction centre

Q

What is the fourth step of the light dependent reactions of Photosynthesis?

A

Q

What is the difference between chloroplast and chlorophyll?

A

chlorophyll is food producers of the cell which are present in green plants, found inside the chloroplast.

Q

What is carbon fixation?

A

The process of converting carbon dioxide into a starting molecule in the Calvin Benson Cycle

18
Q

What are the products of the Calvin Benson cycle

A

Glucose, ADP, NADP+,
