Question

Cut-Paste each of the following events into the correct box below.

Once all items are in the correct box, re-arrange them into the correct sequence.

• A H⁺ gradient is formed; release of H⁺ from the gradient drives ATP synthesis.
• ATP & NADPH are used to reduce carbons to form the carbohydrate G3P.
• CO₂ is brought into the plant & fixed to RuBP.
• Electron is caught by PS 1; additional light excites the electron.
• Excited electron is passed down an Electron Transport Chain.
• Excited electron plus H⁺ is given to NADP⁺ to make NADPH.
• Five G3P molecules are used to regenerate 3 RuBP molecules while 1 G3P is saved to make glucose.
• Light excites an electron in Photosystem 2.
• Water is split to replace excited electron; oxygen is produced.

Calvin Cycle

Answer 1

Calvin Cycle: Co2 is brought into the plant & fixed to RuBP.

ATP and NADPH are used to reduce carbons to form the carbohydrate G3P.

Five G3P molecules are used to regenerate 3 RuBP molecules while 1 G3P is saved to make glucose.

Light reaction: Light excites an electron in photosystem2.

Electron is caught by PS1;additional light excites the electron.

Excited electron is passed down an Electron Transport Chain.

Water is split to replace excited electron;oxygen is produced.

   A H+ gradient is formed; release of H+ from the gradient drives ATP synthesis.

Excited electron plus H+ is given to NADP+ to make NADPH.
