What does ATP consist of? |
|
Definition
Adenine, a 5-carbon sugar called ribose, and three phosphate groups. |
|
|
Term
How is ADP different from ATP? |
|
Definition
ADP has two phosphate groups. |
|
|
Term
How is energy added to ADP and what does it change into? |
|
Definition
A phosphate group is added and it changes into ATP. |
|
|
Term
What are some functions that ATP can preform? |
|
Definition

|
|
Term
How is energy released from ATP? |
|
Definition
The third phosphate group breaks off. |
|
|
Term
How much ATP are in cells? And why? |
|
Definition
Very little, Because ATP is not good for storing large amounts of energy, and only a few seconds of energy comes out of ATP |

Definition
|
|
Term
Where do each reaction take place? |

Term
How does NADP+ become NADPH? |
|
Definition
When NADP+ holds high-energy electrons and a hydrogen ion |
|
|

|
Definition
|
|
Term
What do Light-Dependent Reactions (LDRs) produce? |
|
Definition
|
|
Term
How does photosynthesis begin? |
|
Definition
When the pigments in photosystem 2 absorb light. |
|
|
Term
Describe the process of LDRs |
|
Definition
Pigemts abosorb sunlight in Photosystem 2, then High Energy Electrons are passed through the electron transport chain, then the electrons are recharged in photosystem 1 and form NADPH, then hydrogen ions move to the thylakoid membrane, finally, the hydrogen ions pass through ATP synthase and the energy is used to convert ADP to ATP. |
|
|
Term
|
Definition
A protein on the membrane of the thylakoid, and H+ ions pass through it |
|
|
Term
Who was the Calvin Cycle named after? |
|
Definition
|
|
Term
Describe the Calvin Cycle |
|
Definition
First, six CO2 molecules enter and combine with six 5-carbon molecules and produce twelve 3-carbon molecules, then ATP and NADPH give the molecules more energy, then two 3-carbon molecules are removed to produce other compunds, the the remaining ten 3-carbon molcules are converted into six 5-carbon molecules to be used in the reaction again. |
|
|
Term
What factors affect photosynthesis? and at what levels? |
|
Definition
Water (more water speeds up photosynthesis), Temperature (between 0-35 degrees Celsius), Intensity of light (eventually peaks) |
