Photosynthesis: how plant feed the world Flashcards
on the electromagnetic spectrum, what is the photosynthetic active radiation (PAR)
400 to 700 nm
true or false. the larger the wavelength, the higher the energy is
false. a shorter wavelength correspond to higher energy
from what is composed the light
particle of energy
what happens when a metal is expose to a wavelength
metal is positively charged. an electron is dislodge
how can we describe the incandescent phenomenon
an electrical current pass through thin filament, the heat excite the metal
What is a pigment
a substance that absorb te light and transmit it
what does the electron in the pigment
boosted to higher energy level
What are the four effect of this change in energy
heat, fluorescence, resonance energy transfer, electron transfer
name the four main plant pigment
chlorophyll a, chlorophyll b, carotenoid, phycobilins
what is the main function of chlorophyll a
split water and generate oxygen
what is the main function of chlorophyll b
transfer energy to chlorophyll a
what happens in the light reaction
ATP is formed and NADP+ is reduce to NADPH
what happens in the Calvin cycle, dark reaction
the carbon fix sugar and the ATP and NADPH are used
where occurs the light reaction
in the thylakoid membrane of the chloroplast
what is the function of accessory pigment
transfer energy through resonance energy transfer
