The Equation
What are the reactants of Photosynthesis
Carbon dioxide and water and sunlight
CO2 and H2O and energy
Organelle where photosynthesis occurs
Chloroplast
Another name for the Calvin Cycle is
The Light Independent Reaction
A chemical pathway that produces carbohydrates from energy of various chemicals without using energy from sunlight.
Chemosynthesis
This occurs when electrons are added to a molecule
Reduction
What are the products of Photosynthesis?
Carbohydrate and Oxygen gas and water
(C6H12O6) and O2 and H2O
Pigment that captures sunlight during photosynthesis
Chlorophyll
What are the steps of the Calvin Cycle?
1. The Fixation Phase
2. The Reduction Phase
3. The Regeneration Phase
The most common alternative photosynthetic pathway that is performed by most plants when CO2 concentration is low
C3 Pathways
NADP+
Oxidized
What is the balanced equation for Photosynthesis?
6 CO2 + 12 H2O --> C6H12O6 + 6O2 + 6 H2O
Products produced during the light Reaction
Oxygen gas (O2)
NADPH (carries electrons)
ATP
What are the products produced by the end of the Calvin Cycle?
H2O
G3P
The Stomata will only open during the night when it is cooler so as not to lose much water. The C atoms are fixed to various molecules until morning when the light reaction begin and photosynthesis can continue
CAM Pathway
NADPH after the Calvin Cycle
By the end of the Calvin Cycle, NADPH will be Oxidized to NADP+
Oxidized
Which Reactant donates the Carbon atoms for the carbohydrate product.
CO2
The Enzyme that creates ATP during the Light Reaction
ATP Synthase
What molecule from the Calvin Cycle is C fixed to?
RuBP
Rubisco fixes O2 instead of CO2 as Oxygen builds up because the stomata is closed
C3 Pathways
NADP+ after the Light reaction
By the end, NADP+ will be NADPH which is Reduced
Which reactant donates the Oxygen atoms for the O2 gas that is produced
H2O
Electrons that move through the electron transport chain are replace from where?
The electrons are replaced from electrons from a water molecule.
What enzyme fixes carbon during the Calvin Cycle?
Rubisco
Uses PeP Carboylase (PEP) to fix C when CO2 concentrations are low as PEP has a higher affinity for CO2 than O2
C4 Pathway
G3P during the Calvin Cycle
Reduction
