Where in the cell does photosynthesis occur?
Write the chemical equation of photosynthesis
Light + CO2 + H2O = Glucose & Oxygen
What are pigments?
They are molecules that absorb light.
What are carotenoids and how do they help plants?
Carotenoids are accessory pigments and they help by aborbing blue & green pigments.
Name 2 things that excited electrons from chlorophyll help generate.
NADPH & ATP
Where in the chloroplasts do the light-dependent reactions occur?
Where does the energy come from to fuel the light-independent reactions?
From light-dependent reactions.
What does RuBisCO do for the cell?
RuBisCo captures CO2 & combines it w/ Ribulose to make an unstable 6 carbon molecule.
What do the photosystems do and where are they located?
They capture energy from light and are located in the Thylakoid Membrane.
Name 2 difference between photosystems I & II.
PS II splits water and occurs first.
PSI makes NADPH and occurs second.
What is added to CO2 to help generate glyceraldehyde-3-phosphate during the Calvin Cycle?
Name5 producrs glyceraldehyde-3-phosphate can be used to make.
Describe what this picture is illustrating.
Photosynthesis and Aerobic Respiration rely on each other to function.
What makes plants green?
Where do Light-Independent reactions occur?
Light-Capturing Events: The Details
When a photon hits a pigment molcule, electrons are excited....
Electrons moves on to make ATP, the Chlorophyll needs another electron so it breaks down water and steals its electron. (Releases oxygen)
