Chapter 10 Flashcards
Where does the Calvin Cycle occur?
Storma
What is NADPH
It is NAD+ with a PH group on it, it acts as a temporary store for energized electrons
What is Light Reactions
The first phase of Photosynthesis, where light is converted into ATP and NADPH in thylakoid membranes.
H2O is taken and O2 gas is given off
What is the Calvin Cycle
2nd phase of photosynthesis where CO2 is reduced into carbohydrates (sugars), occurs in the Stroma as well.
Reaction-center complex
a complex of proteins surrounded by chloropyll A and Electron Acceptors
What is a light-harvesting complex
Supporting chlorophylls and caratenoids which capture mroe light and give it to the reaction-center
Autotrophs
Organisms that do not need to feed on other organisms, as they create their own energy
Heterotrophs
organisms that do not create their own energy, and need to feed on others.
Chloroplasts
Found in the mesophyll (interior of plant cell).
Stomata
Where CO2 enters the leaves
Chlorophyll
Green pigment that gives leaves their color, resides in thylakoid membranes
NADPH
Stores energized electrons
Thylakoids
Little pancakes that convert light energy into ATP
What happens when photons hit chlorophyll
Electrons in the chlorophyll are excited, causing energy to be released
Photosystem II
A light-capturing system in the chlorophyll containing P680 C-A cells, which are best at taking in 680nm light
Photosystem I
A light-capturing system in the chlorophyll with P700 cells.
Linear Electron Flow
Linear electron flow is the process during the light-dependent reactions of photosynthesis where electrons move in a linear path through the photosynthetic electron transport chain to produce ATP and NADPH.L
Linear Electron Flow passage
Electrons travel through PS (II) and make ATP as they travel to PS (I), which ends with producing NADPH
What are ATP and NADPH used for in the Calvin Cycle
They are used to convert CO2 into glucose and other organic molecules
What are the three steps of The Calvin Cycle
Carbon Fixation
Reduction
Regeneration
