KK4 - light dependent stage + light independent stage

Inputs/outputs - LDS

• using sunlight, 18 ADP and Pi join together to create 18ATP

  • ATP is a coenzyme that is needed by the LIS

• 12 H2O molecules and 12 NADP+ molecules are joined together to make 12 NADPH molecules

  • Don’t need oxygen, so 6 molecules of O (from H2O) get outputted

  • light breaks the binds btwn. water to make 24H and 12O

Inputs/outputs - LIS

• 18 ATP + 12 NADPH + 6CO2 molcules are the inputs of LIS

• 6 H2O are the outputs

Process of LDP

• inside the thylakoid, ATP synthase turns 18ADP and Pi into 18ATP

• half of H+ molecules join to create NADPH

• other half moves down its concentration gradient to generate ATP

ATP to ADP

Phosphate gets broken off ATP (to make ADP + Pi). This generates a small amount of energy

• ATP = charged form, ADP = uncharged form

NADPH to NADP+

NADPH formed in light-dependent reaction donates hydrogen ions and electrons

• NADPH = charged form, NADP = uncharged form
