Chapter 8: Photosynthesis

MATES Biotechnology, Sprague 2024

where do carbon atoms in glucose come from?

carbon dioxide from the air

what are the requirements of photosynthesis?

sunlight, carbon dioxide, water

how many turns of the calvin cycle produce glucose?

6 turns

where does photosynthesis take place?

in thylakoids

what are thylakoids?

disks inside of the chloroplasts, where the ETC take place

role of water in photosynthesis?

donates protons and electrons to the ETC

role of RUBP

carbon fixation: turns inorganic carbon into an organic form

what are photons?

a particle of light, bundle of energy

primary pigments

produces a majority of the energy for photosynthesis (chlorophyll)

accessory pigments

secondary light-absorbing pigment that absorbs photons that primary pigments cannot; doesn’t produce as much energy (carotenoids)
