Thylakoids contain clusters of chlorophyll and proteins known as ___________________.

• chloroplasts

• stroma

• photosynthesis

• photosystems

Clusters of chlorophyll absorb sunlight and high-energy generate ________________ pass along the ________________.

• electrons, photosystem chain

• protons, oxygen receptor

• electrons, electron transport chain

• sodium ions, oxygen receptor

The light-independent reactions of photosynthesis are also known as _______________.

• Calvin Cycle

• ATP synthase

• photosystem 1

• photosystem 2

During the light-independent reactions, energy from ATP and ___________ is used to assemble high-energy sugars.

• carbon dioxide

• NADPH

• sugar

• water

ADP becomes ATP by:

• gaining a phosphate group

• loosing an adenine group

• loosing energy during a chemical reaction

• transferring chemical energy to another compound

The end products of the light dependent reactions are:

• Oxygen, ATP, NADPH

• CO2, PGAL, Hydrogen

• H2O, ADP, NADP

• PGAL, ADP, ribulose

The oxygen gas produce in photosynthesis is generated by:

• splitting of CO2

• reduction of PGAL

• splitting of water during light independent reaction

• synthesis of ATP

Where does the light independent reaction occur?

• cytoplasm of cell

• outer membrane of chloroplast

• thylakoid membrane

• stroma

Which is true about chlorophyll?

• It absorbs green light

• It absorbs red and blue light the best

• It is not necessary for photosynthesis

As light intensity increases, the rate of photosynthesis would:

• increase

• decrease

• remain the same
