Team Challenge: How many phosphate groups do AMP, ADP and ATP have respectively?
1,2,3

What is the difference between the lumen and stroma?
lumen = inside of thylakoid stroma = space around (outside) a thylakoid in a chloroplast.
100
Individual Team Challenge: What allows H+ to move into the lumen (high concentration of H+) from the stroma (low concentration of H+)?
ATP formed by the energy released from the electron transport chain. The energy released through the ETC combines with ADP and a phosphate group to produce ATP.
100
Team Challenge: Light-Independent Reactions are also called...
The Calvin Cycle
100
Individual Team Challenge: Define Organic Matter.
matter made by a living organism during its natural growth
200
Team Challenge:True or False: ADP can never be used as an energy source.
False
200
Team Challenge: Draw the __________________.
Thylakoid membrane
200
Individual Team Challenge: Define chemiosmosis
When H+ from the lumen goes through ATP synthase to the stroma. This process binds ADP with a phosphate group to make ATP.
200
Team Challenge: What is the name of the enzyme that combines CO2 with RuBP?
Rubisco
200
Individual Team Challenge: Define Autotroph
What is Organism capable of making nutritive organic matter from inorganic sources.
300
Team Challenge: Write the equation for the conversion of ADP to ATP
ADP + P + E --> ATP
300
Individual Team Challenge: Why are plants green?
The dominant pigment found in photosystem II (or thylakoid membrane or chloroplast) is chlorophyll which absorbs every wavelength from the visible light spectrum except the wavelength associated with the color green which is reflected back into the environment.
300
Individual Challenge:: What are the final products of the light reactions (cyclic photophosphorylation)?
O2, NADPH, ATP
300
Team Challenge: 12 PGA molecules (formed by the splitting of the unstable 6 carbon sugar intermediate) in turned into 12 PGAL molecules by the addition of ____________ and _____________.
12 ATP molecules and 12 NADPH
300
Team Challenge: Write the balanced equation for photosynthesis.
6 CO2 + 6 H20 --> C6H12O6 + 6 O2
400
Individual Team Challenge: Where is energy stored in an ATP molecule?
In the phosphate bonds (Phosphate groups are negatively charged. Because they are next to each other and they each have negative charges which repel one another, there is a build up of potential energy in the molecule).
400
Team Challenge: Sculpt the _________________.
Electron transport chain
400
Team Challenge:Draw __________________________________.
Photosystem 2 and 1
400
Team Challenge: Out of 12 PGALs, how many are used to make glucose?
2 PGAL molecules are used to make a glucose molecule
400
Team Challenge: Write out the balanced equation for photolysis.
H2O --> 1/2 O2 + 2H+ + 2e
500
Individual: List 3 cellular activities which require ATP.
Multiple answers possible: active transport, protein synthesis, cell division, etc.
500
Individual Team Challenge: What purpose do accessory pigments such as carotenoids, phycobillins and anthocyanins have with regards to photosynthesis?
They absorb wavelengths of light different than those absorbed by chlorophyll. Once they absorb light, they transfer their energy to chlorophyll which feeds the light-dependent reaction to produce ATP and NADPH. They make it possible for photosynthetic organisms to use a broader range of the visible light spectrum.
500
Team Challenge: Draw ___________.
ATP synthase.
500
Individual Team Challenge: How is RuBP replenished at the end of the cycle?
PGAL molecules not used to make glucose combine with ATP to replenish RuBP.
500
Individual Team Challenge: What is the difference between non-cyclic and cyclic photophosphorylation?
non-cyclic photophosphorylation involves photolysis where 2 electrons from every water molecule being oxidized are transferred to the chlorophyll molecule of photosystem 2. At the end of the cycle, O2, NADPH and ATP are produced. Cyclic photophosphorylation involves the recycling of electrons. The excited electron from photosystem 1 goes through the electron transport chain but never makes it to NADP+ and instead returns to photosystem 1. No O2 nor NADPH is formed during cyclic photophosphorylation, only ATP is made.
