Q

Light Dependent Reaction

A

Chlorophyll absorbs energy from sunlight,The energy is broken down in the thylakoids membrane. H2O molecules are broken down and O2 is released. Energy is transformed into ATP.

Q

Light Independent Reactions

A

Use energy from Light dependent reactions to make sugars. Happens in the stromas of chloroplasts. CO2 is used to build larger molecules. Glucose is formed.
