|
|
||||
|---|---|---|---|---|---|
| Photosynthesis | Light energy is captured and used to synthesize carbohydrates
🗑
|
||||
| Heterotrophs | Must eat food to sustain life
🗑
|
||||
| Autotroph | Make organic molecules from inorganic sources
🗑
|
||||
| Photoautotroph | uses light as a source of energy
🗑
|
||||
| chloroplast | Organelles in plants and algae that carry out photosynthesis
🗑
|
||||
| Chlorophyll | Green pigment used in plants to produce sugars
🗑
|
||||
| Stomata | Holes in a leaf through which carbon dioxide enters and oxygen exits
🗑
|
||||
| Thylakoid Membrane | third membrane that contains chlorophyll pigment molecules
🗑
|
||||
| Granum | Stack of thylakoids
🗑
|
||||
| Two Stages of Photosynthesis | Light reactions and Calvin Cycle (light-independent reactions)
🗑
|
||||
| PSII | Chlorophyll P680; excited electrons travel to PSI using water that is oxidized
🗑
|
||||
| PSI | Chlorophyll P700; primary role is NADPH production
🗑
|
||||
| Noncyclic Electron Flow | Electrons produced by the splitting of water molecules travel to PSII, PSI, and NADPH
🗑
|
||||
| Cyclic Electron Flow | Electron cycling releases energy to transport H+ into lumen driving synthesis of ATP
🗑
|
||||
| Photosystem II (PSII) | Light-harvesting complex or antenna complex, and reaction center
🗑
|
||||
| Light-harvesting complex | Directly absorbs photons; energy is transferred via resonance energy transfer
🗑
|
||||
| Reaction Center | P680 (excited state); relatively unstable, transferred to promary electron acceptor, electrons are removed from water to "replenish" P680
🗑
|
||||
| Z Scheme | Zigzag shape of energy curve that invovles increases and decreases in the energy of an electron as it moves from water to PSII to PSI to NADP+
🗑
|
||||
| Calvin Cycle | ATP and NADPH are used to make carbs; CO2 is incorporated into the carbs
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
