Chapter 10: Photosynthesis Flashcards
What is photosynthesis
The process of converting light energy into chemical energy directly or indirectly
Autotroph
Produce and consume their own energy
Heterotroph
Consume others to get energy
Decomposers
Most bacteria and fungi leave on energy of decomposing organic things
What thing on the leaves let gases and water in and out
Stomata
Where can chloroplasts be found
On mesophyll cell
Chloroplasts structure
Two membranes, fluid called “Stroma”, thylakoid “a coin”, stack of thylakoid is granum. Singular is grana
Where does chlorophyll found in chloroplasts?
In thylakoid membranes
What are two stages of photosynthesis
- Light reactions (light dependence)
2. Calvin cycle (Light independence)
Light reaction reactants
H20 and sunlight
Light reaction products
O2
Where does light reaction occur
In the thylakoids membranes of the chloroplasts
What acts as an electron carrier in light reaction
NADPH (NADP+ reduced form)
Carotenoid
Pigments
Spectrophotometer
Detect….
Which type of chlorophyll helps with photosynthetic
Chlorophyll a
What is photosystem
a light-capturing unit located in thylakoid membranes consists of a reaction-center complex surrounded by numerous light-harvesting complexes.
What light dependence reactions consist of ?
Two photosystems and two electron transport chains.
Which photosystem produces ATP
Photosystem II
What does electron transport chain do in photosynthesis
Pump H+ into thylakoid spaces to run ATP synthase
Where is the higher concentration of H+ found
In thylakoid space
What photosystem produces NADPH
Photosystem I
Where does Calvin cycle occur
In the stroma
Calvin’s cycle reactant
CO2
