Unit 1 lesson 4

PHOTOSYNTHESIS

QuestionAnswer
plants gather the sun's energy with light absorbing molecules called pigments
what is the main pigment in plants chlorophyll
name 2 two types of chlorophyll chlorophyll a and chlorophyll b
what absobed light well in the blue violet and red regions of the light spectrum chlorophyll
what does not absorb green but reflects green chlorophyll
pklants have other pigment that absorb wavelengths of light but aren't noticed due to so much green pigments red and orange
what is photosynthesis taking place in organelles chloroplast
chloroplast contain sac like synthesisess called thylakoids
thylakoids are inner connected and arranged in stacks known as groma
where are pigment located thylakoid membranes
what is the fluid portion of the chloroplast outside of the thylakoids stroma
what does chlorophyll absorb especaially well light
a large fraction of light energy is transferred to _ in the chlorophyll molecule electron
raising energy levels of electrons alows light energy to produce a steady supply of high energy electrons making _ work photosynthesis
high energy electrons produce by chlorophyll are high _ and require a _ reactive; special carrier
what is a compound that can accept a paiur of high energy electrons and transfer them along with their energy along with their molecule electron carrier 3x. NADP
this accepts and holds 2 high energy electrons along with a hydrogen ions and converts to _ NADPH
photosynthesis uses the energy of _ to convert water to carbon into high energies _ and __ sunlight, sugars, oxygen
what is a set of reactions in photosynthesis that uses energy from light to produce ATP in NADPH light dependent reactions
light dependent reactions take place within the what thylakoid
set of reactions that does NOT require energy from ATP and NADPH light independent reactions
