Photosynthesis Flashcards
Where are chloroplasts found?
In the palaside mesophyll and guard cells of leaves
What is photosynthesis?
The conversion of simple organic compounds into more complex organic compounds using light energy
What are the four main pigments?
Chlorophyll a, chlorophyll b, carotene and xanthophyll
What does the action spectra show?
The rate of photosynthesis at different wavelengths of light.
How do plants protect chlorophyll from high light intensities?
Carotenes absorb blue light
In the light dependent stage, when ATP is formed, what is it called?
photo phosphorylation
What is the five carbon acceptor molecule in the LIS?
Ribulose biphosphate
What is formed?
A 6C molecule that immediately splits into 2 molecules of glycerate phosphate
What is formed when GP is phosphorylated and reduced?
Triose phosphate
How is Ribulose biphosphate regenerated?
Triose phosphate enters a series of reactions driven by ATP
What does a lack of nitrogen cause?
Stunted growth and yellowed leaves (due to inadequate chlorophyll production)
