|
Definition
|
|
Term
| The chemical products of the light reactions are oxygen, |

|
Term
| The stage of photosynthesis that uses the most ATP molecules is: |
|

Term
| What is the chemical equation for photosnthesis? |
|
Definition
6 CO2 + 6 H2O >>> C6H12O6 + 6 O2
In the presence of light energy |

Term
| What is the role that the stomata in plant's leaves play in photosynthesis? |
|
Definition
| Carbon dioxide enters the leaf and oxygen exits the leaf through the stomata. (singular: stoma) |
|
|
Term
| Describe the three things that could happen to light of a particular wavelength after it strikes a leaf. |
|
Definition
| Green light would hit the leaf, being absorbed into some of the molecules, the electrons would go to the extremely unstable "excited state" and pushes back down, giving the energy to the nearest molecule, which would follow the same pattern until it when to the reaction center of the photosystem. |
|
|
Term
| Describe how ATP is generated during the light reactions. |
|
Definition
| The light reactions that take place in the thylakoid membranes convert light energy to the chemical energy of ATP and NADPH. |
|
|
Term
| Why is the term "light-independent reactions" a misleading description of the Calvin cycle? |
|
Definition
| Though it does not directly require sunlight, it needs the ATP and NADPH produced by the photosynthesis. |
|
|
Term
| What is the significance of the sugar G3P? |
|
Definition
| G3P is not yet glucose, but the plant cell uses G3P as the raw material to make glucose and the other organic molecules that it needs. |
|
|
Term
| How does the processes of photosynthesis and cellular respiration each contribute to the carbon cycle? |
|
Definition
| The photosynthesis uses light energy and carbon dioxide to create oxygen and sugar, which is eaten by a consumer who uses cellular respiration to produce the carbon back as a waste product. |
