Place the steps of the Calvin Cycle in order.

• reduction (converts ATP; produces glucose)

• carbon fixation (puts Co₂ into an organic molecule)

• regeneration (remakes RuBP or ribulose to restart cycle)

Why can't plants survive without water?

• The splitting of water fixes carbon dioxide in the Calvin cycle, allowing for the production of G3P.

• The spitting of water provides the electrons needed to turn ADP to ATP in the Calvin Cycle.

• Oxygen is provided during the splitting of water, which is necessary for plant tissues.

• The electrons gathered from the splitting of water allow for the conversion of NADP+ to NADPH in the light-dependent reactions.

The light-dependent reactions occur in the ​ ​ (a)   and the Calvin cycle occurs in the ​​ (b)   .

• thylakoids
• stroma
• cytoplasm
• mitochondria

Put the energy conversions in order starting with where all energy comes from.

• Chemical energy stored in glucose and goes into

• Sunlight energy goes into

• Chemical energy in ATP that can be used

• Photosynthesis to convert it to

• Cellular respiration converts it to

What is the relationship between the reactants and products of photosynthesis and cellular respiration?

• They both create the same things.

• Photosynthesis and cellular respiration have no relationship.
• The reactants and products of photosynthesis and cellular respiration are completely different.
• The reactants and products of photosynthesis and cellular respiration are complementary and interconnected.
