|
Site of the Calvin cycle or light-independent reactions |
Thylakoid |
|
|
Reactants of Photosynthesis |
CO2, H20 |
|
|
Organelle reactants are stored in before use in photosynthesis |
Stroma |
|
|
Where do light dependent reactions occur |
Thylakoid |
|
|
Where do light independent reactions occur |
Stroma |
|
|
What is produced during synthesis |
Sugar, oxygen, water |
|
|
Why are 6 CO2 needed in the chloroplast? |
To produce the sugars |
|
|
Where are electrons released from chlorophyll by a photon of light from the sun? |
Photosystem II and Photosystem I |
|
|
Where are electrons released from water molecules? |
Photosystem II |
|
|
When electrons are released from water molecules, what other products are formed? |
O2 and H+ |
|
|
Explain light dependent reactions (similar to electron-transport chain |
Use the energy of light to drive electrons along ETC. Use this energy to pump protons across membrane to generate a H+ gradient. Use this gradient to drive ATP synthase and create ATP from ADP + Pi. |
|
|
Name the embedded protein complex found in the thylakoid membrane that uses excited electrons to reduce NADP+ into NADPH |
Photosystem I |
|
|
Name the embedded protein complex found in the thylakoid membrane that provides excited electrons to the electron transport chain |
Photosystem II |
|
|
Name the embedded protein complex found in the thylakoid membrane that converts ADP +Pi into ATP using free energy from the flow of Hydrogen ions |
ATP Synthase |
|
|
What is the source of replacement electrons for those released from photosystem II? |
H2O is split |
|
|
What is the source of replacement electrons for those released from photosystem I? |
Electron from ETC (generated at Photosystem II) |
|
|
Is carbon dioxide involved in the light-dependent reaction? |
No |
|
|
Where do ATP and NADPH produced during the light dependent reactions go when the process is complete? |
To the stroma |
|
|
What component is used by the Calvin cycle to generate glucose? |
CO2 |
|
|
Where did the ATP and NADPH molecules used in the Calvin cycle come from? |
Light dependent reactions |
|
|
Where in a mitochondrion is the highest concentration of hydrogen ions (H+) located? |
Intermembrane space |
|
|
How to hydrogen ions reach the intermembrane space? |
Proton pumps in inner membrane pump into intermembrane space |
|
|
Why is energy required to move hydrogen ions across the membrane in the direction indicated in Model 1? (Arrows point from outside to intermembrane space) |
Pumping against concentration gradient |
