What is needed by the Calvin Cycle?

Answer 1

The Calvin cycle is a 'light independent cycle' that takes place in the chloroplasts. In this cycle, water and carbon dioxide is converted into organic compounds. The key enzyme involved is Rubisco.

Answer 2

The Calvin Cycle

First stage: Fixation

• Light-independent reactions are initiated
• CO2is fixed from an inorganic to an organic molecule
• CO2 diffuses into the Stroma from surrounding Cytosol
• An Enzyme combines a CO2 molecule with a Five-Carbon Carbohydrate called RuBP
• A Six-Carbon molecule is created that splits immediately into a pair of Three-Carbon molecules known as PGA

Second stage: Conversion

• ATP and NADPH are used to reduce 3-PGA into G3P
• ATP and NADH are converted to ADP and NADP+
• PGA is converted into another Three-Carbon molecule, PGAL

Third stage: Regeneration

• RuBP is regenerated
• The system prepares to fix more CO2
• Most PGAL is converted back to RuBP
• Some PGAL leaves the Calvin Cycle and are used by the Plant Cell to make other organic compounds

Answer 3

Light, water and carbon dioxide are required in the calvin cycle, 3 photons, 3 water molecules, and 3 carbon dioxide, although most people refer to photosynthesis and making glucose, requiring 2 calvin cycles

Answer 4

Carbon Dioxide.

They also need RuBP. Combination of these to gives 2 PGA molecules

Answer 5

Co2, ATP, and NADPH are needed for the Calvin Cycle.

Answer 6

The Calvin cycle uses carbon dioxide, with the ATP and NADPH produced in the light dependent part of photosynthsis.

Answer 7

three carbon dioxide molecules

Answer 8

ATP, NADPH + H+, Carbon Dioxide

Answer 9

RuBP Carboxylase
