Unit 3-Photosynthesis Flashcards
Number of stages in photosynthesis
2
First stage of photosynthesis in which water is split
Light reactions
Molecule which traps light energy from the sun
Chlorophyll
Leaf organelle which contains chlorophyll and is the site of photosynthesis
Chloroplast
Energy rich molecule synthesised during the light reaction
ATP (adenosine triphosphate)
Type of energy in ATP
Chemical energy
Required to synthesis ATP
ADP + Pi + energy
Produced when water is split
Hydrogen and oxygen (and energy)
A by-product of water splitting that diffuses out of the leaf
Oxygen
Carries hydrogen from the first to the second stage
Hydrogen Acceptor
Second stage of photosynthesis where glucose is synthesised
Carbon fixation
Controls the series of photosynthesis reactions
Enzymes
Produced by water splitting and combines with carbon dioxide to produce glucose
Hydrogen
Substance required to produce glucose
Hydrogen, carbon dioxide and ATP
Product of photosynthesis that can be used in respiration or converted to other molecules
Glucose
