photosynthesis Flashcards
equation of photosynthesis?
light energy
water + carbon dioxide > oxygen + sugar
chlorophyll
where is light absorbed?
is captured in the chlorophyll that is located in the chloroplast.
what is the first stage of photosynthesis called?
light reaction
what is the second stage of photosynthesis called?
carbon fixation
what are the 3 limiting factors of photosynthesis?
light intensity, carbon dioxide concentration and temperature
describe the first stage of photosynthesis.
light is captured in the chlorophyll which is converted into chemical energy to make ATP. Water is split to make hydrogen and Oxygen.
describe the second stage of photosynthesis.
( enzymes control the reaction ) Hydrogen and ATP from the light reactions combine with carbon dioxide to make sugar
what is 3 ways sugar can be used?
energy source, energy storage and building material
what is the role of chlorophyll?
traps light energy from the sun.
where is the chlorophyll located?
in the chloroplast.
Name the form of energy is light energy converted too during the light reactions.
chemical energy
what is the molecule that this this energy is used to generate?
ATP
when water is split it creates two products. Name both of the products.
hydrogen and oxygen
What is the two products produced during the light reactions which are required for the second stage of photosynthesis?
ATP and hydrogen
