photosynthesis Flashcards
what is photosynthesis
it’s when a plant gets nuitraints from the sun
define oxidation
this is when a compound loses an electron
define reduction
this is when a compound gains an electron
what is this is it called when oxidation and reduction are happening
a redox reaction
what is a light dependent reaction called
photosynthesis or light reaction
what is a dark or depened reaction called
the Calvin cycle
list the reagents and products of photosynthesis
H2O and CO2
what is the source of the oxygen released during photosynthesis
water
whats the role of atp in photosynthesis
it’s the light energy and works like a battery
whats the role of NADPH
it’s to carry the ectrons and hydrogen to the Calvin cycle
whats carbon fixation
it’s the spilting of the carbons
whats the role of the Calvin cycle
it’s to make glucose to keep the plant alive
what are the three parts to the Calvin cycle
fixation, reduction, regeneration
Pgal or G3p
it doesnt matter there the same
what is atp
it makes food and engery for the plant to grow
how does atp and adp connect
when atp breakdown energy is realised adn that energy creates ADP
what light is aborb and what light is refeclted in photosynthesis
green light is reflected while blue and red light is absorbed
whats a photosystem
a cluster in the tylakoid that has other pigment and choliphyll
whats the thylakoid
it’s a part of the chloroplast is a flatted ouck stacked called grama and has chloropyhll in it
what makes chlorophyll green
chlorophyll does not absorb green light it reflects it
what does it mean when electrons get existed
it means that the electron is going to a higher energy level then others
which is first photosystem 1 or 2
2
what numbers are involed in the calvin cycle
6 carbons unstable then moves to a 12 carbon stable then it relses 2 pgal are relseds leaving 10 then there 6 rubp
what is carbon dioxide fixation
means that carbon dioxide is is bonded to a already existing moulcoule this is RuBP
which releases energy: antbolic metabolic pathways or catabolic metabolic pathways
catabolic: it breaks down breaks down larger molocules and antbolic synthesis larger molcoules vfrom smaller ones it requires energy
