Answer 1

Light-dependent

• Sun light activated chlorophyll splits the H20 molecules
• Oxygen is released to the environment
• H+ is 'carried by electron carriers (NADP+) to light-independent reaction
• ADP + P is turned into ATP

Light-independent

• Uses carbon dioxide from the environment
• Uses the electrons (carried by NADPH) and ATP from the light dependent reaction as source of energy
• Builds CH1,0 molecules (aka, glucose/carbohydrates/sugars)

Step-by-step explanation

The light-dependent reactions of photosynthesis require energy from the sun to split a molecule of water into hydrogen and oxygen. The oxygen is released and the hydrogen ions are used as energy for the next steps, as is ATP.

In the light independent reactions, sugar is made from carbon dioxide using the energy from the light-dependent steps
