Light harvesting complex
(antenna complex) subunit of proteins and photosynthetic pigments - major function: to collect photon energy and transfer the energy toward the reaction center
CAM plant (Crassulacean acid metabolism)
adaption for drought conditions, CO2 enter the stomata at night
Heliotropism
sun-induced movement of plant organs (sunflowers)
Glycolysis
respiration pathway where hexose sugar is oxidized to produce two molecules of pyruvate (produce small amounts of ATP and NADH)
The cholorplast electron transfer chain is located in the ____ whereas the calvin cycle takes place in the _____
thylakoid membrane; stroma
The light reactions of photosynthesis in plants
result in the splitting of H2O yielding O2
What is the correct sequence of electron transfer in photosynthesis
Water to P680 to cytochrome b6f complex to P700 to P700* to NADPH
The initial carbon dioxide acceptor of the C4 pathway is
phosphoenolpyruvate
what is the main advantage for plants that use the C4 pathway in addition to the calvin cycle for the fixation of carbon dioxide
the C4 pathway avoids the oygenation of RuBp in mesophyll cells
the synthesis of sucrose from hexose in plants is catalyzed mainly by __
sucrose 6 phophate synthase (S6PS) and sucrose 6-phosphate phosphatase (S6Pase)
when there is excess light, how would plants respond in order to reduce photoinhibition
by adjusting the location of chloroplast inside the cell so that less light is absorbed by the chloroplasts
which is the correct statement about phloem transport
companion cells are connected to the sieve tube elements and provide them with proteins and other metabolites
which is a correct statement about respiration pathways in plants
pyruvate is a major product of the glycolysis pathway
what is a correct statement about glycerolipids in plants
a glycerophospholipid molecule would contain two fatty acids and one phosphate group or modified phosphate
