photosynthesis Flashcards
photosynthesis is
the chemical process by which green pants make their own food
photosynthesis is a series of
enzyme controlled reactions in 2 stages
1st stage of photosynthesis is
light dependent (light reactions)
in the 1st stage of photosynthesis, light energy from the ….. is trapped by …….. and converted into ………. energy which is used to generate …..
in the 1st stage of photosynthesis, light energy from the sun is trapped by chlorophyll and converted into chemical energy which is used to generate ATP
in the 1st stage of photosynthesis, …….. molecules are split to produce………..and ……………..
excess ……… diffuses from the ……… and out of the cell
in the 1st stage of photosynthesis, water molecules are split to produce hydrogen and oxygen
excess oxygen diffuses from the chloroplasts and out of the cell
2nd stage of photosynthesis is
carbon fixation
in the 2nd stage of photosynthesis, ……… from the light reactions is combined with …….. …….. to produce …….
in the 2nd stage of photosynthesis, hydrogen from the light reactions is combined with carbon dioxide to produce sugar
in the 2nd stage of photosynthesis, ……. from the …. is used in the production of ……
in the 2nd stage of photosynthesis, energy from the ATP is used in the production of sugar
the …….. energy in …….. is available for …………
the chemical energy in sugar is available for respiration
sugar not used in ……………. can be converted to plant …………… such as …….. or …….
sugar not used in respiration can be converted to plant carbohydrates such as starch or cellulose
…….. acts as a store of …… in plants while ……. is a main structural component of plant cell …….
starch acts as a store of energy in plants while cellulose is a main structural component of the plant cell wall
a limiting factor is
a variable, that when in short supply, can limit the rate of a chemical reaction such as photosynthesis
the rate of photosynthesis is limited by
temperature, light intensity, carbon dioxide concentration
