Term
| ____are stacks of membranes. |
|
Definition
|
|
Term
| Explain the beginning of the light reaction process. |
|
Definition
| Photosystem II and I have clorophyll on them. Chlorophyll absorbs sunlight and the electrons in chlorophyll molecule will absorb energy and jump to higher energy levels and leave the chlorophyll and move down the electron transport chain. When they pass from protein to protein along the electron transport chain and as they go down, hydrogen ions are pumped into the the thylakoid space through the mebrane (stroma). |
|
|
Term
| During the light reaction process, how does chlorophyll get previously lost electrons back? |
|
Definition
| from water molecules in thylakoid space and the water molecule breaks down. Now all that's left is oxygen, two oxygen atoms bond together and that's how plants give off oxygen. Oxygen leaves through the stromata |
|
|
Term
| chainging NADP to NADPH is a _____reaction. |
|
Definition
|
|
Term
| During the light reaction process, hydrogen ions inside are at low concentrations and they want to get out--tis is called _____. How do the hydrogen ions get out? |
|
Definition
| osmosis; they get out through ATP synthase because the movemnt of hydrogen ions gives energy to the ATP synthase |
|
|
Term
| Everytime a hydrogen ion leaves the thylakoid space, ____gets made. |
|
Definition
|
|
Term
| The ATP syntahse and teh NAdP work together to form_____. |
|
Definition
|
|
Term
| Producing atp is called_____. |
|
Definition
|
|
Term
| What is the photosynthesis equation? |
|
Definition
| 6CO2 + 6 H2O --C6H12O6 + 6O2 |
|
|
Term
| The Calvin cycle is a series of reactions that produce_____before returning to the starting point once more. |
|
Definition
|
|
Term
| The calvin cycle includes what three things? |
|
Definition
| carbon dioxide fixation, carbon dioxide reduction, and regeneration of RuBP |
|
|
Term
| Explain the calvin cycle. |
|
Definition
| carbondioxide from the atmosphere is attached to RuBP, a five carbon molecule. The result is one six carbon molecule. This six carbon molecule splits into two 3 carbon molecules. The first 3 carbon molecule is called 3PG. The second time of the calvin cycle, the three carbon molecule is called BPG and the third time it is called G3P. |
|
|
Term
| The enzyme that speeds up the reaction in the calvin cycle is called the _____, which is a protein that makes up about 20 to 50 % of the protein content in chloroplasts. |
|
Definition
|
|
Term
| _____is the product of the calvin cycle that can be converted into all sorts of organic molecules. |
|
Definition
|
|
Term
| What is an example of an organic molecule that results from G3P metabolism? |
|
Definition
|
|
Term
| Normal photosynthesis is called____. The other type is called_____. |
|
Definition
| C3 photosynthesis; C4/cam photosynthesis |
|
|
Term
| When oxygen rises in C3 plants, it combines with RuBP instead of ____. |
|
Definition
|
|
Term
| What is photorespiration? |
|
Definition
| in the presence of light (photo), oxygen is taken up and C02 is released |
|
|
Term
| When weather is hot and dry what kind of plants have an advantage? |
|
Definition
|
|
Term
| What does CAM photosynthesis stand for? |
|
Definition
| crassulacean-acid metabolism |
|
|
Term
| Why is photorespiration wasteful? |
|
Definition
| because it is not a part of the calvin cycle |
|
|
Term
| What is the PEP equation for C4 photosynthesis? |
|
Definition
|
|
Term
| How do C4 plants "fix" CO2? |
|
Definition
| by forming a C4 moelcule prior to the involvement of the calvin cycle |
|
|
Term
| CAM plants open their____at night and also fix CO2 by_____. |
|
Definition
| stomata; forming a C4 molecule |
|
