Chapter 10 Flashcards
Sustain themselves by not eating anything fro living things
Autotroph
Obtains organic material by the second major mode of nutrition
Heterotroph
Light absorbed by chlorophyll drives a transfer of electrons and hydrogen ions from water to NADP
Light reaction
Carbon incorporates into organic molecules. The carbon is then turned into a carbohydrate
Calvin cycle
Organized association of proteins holding a special pair of chlorophyll a molecules
Reaction center complex
Consists of various pigment molecules bound to proteins
Light-harvesting complex
The special chlorophyll a enables them to use the energy from light to boost the electron to a higher energy level and to transfer it to the electron acceptor
Primary electron acceptor
What is the source of energy that excites the electron in photosystem II?
Light
What compound is the source of electrons for linear electron flow?
water
What is the source of O2 in the atmosphere?
Splitting of water
What important events occur in the carbon fixation stage of the Calvin cycle?
CO2 gets attached to RuBP
First organic product of carbon fixation is a 3 carbon compound and 3 phosphoglycerate
C3 plant
Peroxisomes and mitochondria rearrange and split a 2 carbon compound, producing CO2
Photorespiration
The preface of the Calvin cycle within and alternate mode of carbon fixation that forms a 4 carbon product
C4 plant
What compound necessary for photosynthesis is found in the thylakoid?
Chlorophyll
Where are the reactants in photosynthesis stored?
Stroma
What part of the chloroplast do light dependent reactions occur?
Thylakoid
What part of the chloroplast does the Calvin cycle occur?
Stroma
Find a place in light dependent reactions where electrons are released from chlorophyll by a photon of light coming from the sun
Stroma
Find a place in light dependent reactions where electrons are released from water molecules
Photosystem II
When electrons are released from water molecules, what other products are formed?
Oxygen and hydrogen
Name the embedded protein complex found in the thylakoid membrane that uses excited electrons to reduce NADP to NADPH
Photosystem I
