  • Site of the light independent reactions
    Stroma of the chloroplast
  • ETCs use electron energy for doing what?
    to establish an electrochemical/proton gradients
  • 5 points to the team that gives teacher Rochin a key
  • What is the purpose of glycolysis? Say the products as well.
    Is a biochemical pathway that releases energy and splits glucose into smaller compounds. (Pyruvate, NADH, and ATP)
  • You have 30 seconds to write down in sequential order from left to right these words
  • What are the products of the pyruvate oxidation?
    Acetyl CoA + CO2
  • Where do plants mainly get their carbon?
    Carbon dioxide from the environment.
  • Write all the "Inputs" of LDR including electron carriers
    H2O, photons, NADP+, ADP
  • Is it true that NADP+ becomes oxidized ?
    No, it gains e- so it gets reduced
  • How is energy released from ATP?
    Energy is released when chemical bonds are broken.
  • What happens when protons (H+) pass through the ATP synthase in the ETC
    ADP + Pi ----- ATP production
  • Prokaryotic photosynthetic organisms that were responsible for the production of oxygen in the atmosphere.
    Cyanobacteria
  • What is the ultimate goal of the Calvin cycle reactions?
    Make organic products that plants need (Sugars)
  • What are protons?
    H+
  • Write all the "Inputs" of LIR including electron carriers
    CO2, NADPH, ATP
  • Fermentation allows glycolysis to proceed in ___________________.
    the absence of oxygen
  • What are the products of the Krebs cycle? (Include also the electron carriers)
    (CO2 release) NADH and FADH2. ATP.
  • What are ETCs? (Function and composition)
    ETCs are membrane proteins that facilitate coupled reactions using the energy of the electrons
  • Define electrochemical gradient
  • Write in the whiteboard 2 pigments found in the chloroplast
    Chlorophyll a, b.
  • Extra points.
  • Carbon fixation reactions are also known as _________________.
    Light independent reactions
  • What are the components and functions of the photosystems?
    Light capturing units in a chloroplast thylakoid membrane (components: protein + chlorophyll)
  • Site of the LDR
    Thylakoids
