U2T3 Changes to Chemical Reactions

What 2 roles here does light energy from the sun serve in Photosynthesis

• Energizes Electrons

• Splitting Carbon Dioxide

• Splits water molecules

• Stabilizes Glucose

NADPH and ATP are necessary for the Light Independent Processes. Where do they come from?

• They're the products made in the Light Dependent Process of Photosynthesis

• They come from the Energy Fairy if the Carbon Molecule puts a tooth under its pillow

• They come from the air

• They come from prey that the plants chase down and consume

Carbon Dioxide(CO2) combines with a 5-Carbon Compound to create

• An unstable 6-Carbon Compound

• A very stable 6-Carbon Compound

• A 7-Carbon Compound

What is added to Uranium-235 to make it unstable?

• A Helium Nucleus

• A Neutron

• A Proton

• Water

 $CaCO_3\left(g\right)\ +\ CaO\left(s\right)\ ->\ CO_2\left(g\right)$  
Does entropy in this reaction increase or decrease?
