State the site of light dependent reactions

Thylakoid

Describe photolysis

Water splitting up due to light

State the term used to describe the production of ATP via the light dependent reaction. Explain why it is given this name.

photophosphorylation. Addition of a phosphate group due to light

State the term used to describe the process by which electrons move down the electron transport chain. Explain why the term is used.

Redox

State the three products of the light dependent stage.

• NADPH

• ATP

• Oxygen

State the role of the three products of the light dependent stage

• ATP- create ADP + Pi

• NADPH- helps to reduce GP

• Oxygen- respiration or leaves plant

Describe the process of the light dependent stage.

• Light energy excite electrons in chlorophyll

• Electron leaves chlorophyll and enters electron transport chain

• Photophosphorylation

• Photolysis

• Electrons go back to chlorophyll

• NADP reduced

• Oxygen leaves as byproduct
