Light Dependent Reaction Cause and Effect Review

Front

Cause: Plants use CO2, water, and light energy.

Back

Effect: Plants produce glucose and oxygen.

Front

Cause: Plants absorb light from the sun.

Back

Effect: High-energy electrons are produced.

Front

Cause: Electrons need replacement in photosystem II.

Back

Effect: Water is split into hydrogen ions and oxygen gas to replace lost electrons.

Front

Electrons move through the electron transport chain to photosystem I.

Back

Re-energized by the sun to make NADPH from NADP+.

Front

Higher hydrogen ion concentration in thylakoid than stroma.

Back

Concentration gradient.

Front

Cause: Hydrogen ions exit the thylakoid through ATP synthase.

Back

Effect: They provide energy to create ATP from ADP and phosphate.
