Photosynthesis Flashcards
What are the 3 photopigments found in the group of chlorophyll
Chlorophyll A
Chlorophyll B
Carotene
Which of the 3 photopigments found in the group of chlorophyll is the main one
Chlorophyll A
What is a photo system
Clusters of photopigments and proteins which capture light energy
Where are photosystems found
Thylakoid membrane
What is found at the centre of a photosystrm
Reaction centre
What are organisms which photosynthesis classed as
Autotrophs
What is an advantage of the highly folder structure of thylakoid membranes
Provides a large surface area for absorption of photons
Apart from the photopigments from the chlorophyll group, name another
Xanthophyll
Where in a photosystem is chlorophyll A located
Reaction centre
What is everything except the reaction centre known as in a photosystem
Antennae complex
What is the role of the antennae complex
Absorb different wavelengths of light in order to transfer this energy to the reaction centre
What are the two stages of photosynthesis
Light dependant and light independant
What happens in the light dependant stage of photosynthesis
Energy from sunlight is absorbed and used to form ATP, and hydrogen from water is used to reduce coenzyme NADP and NADPH
What happens in the light independant stage of photosynthesis
Hydrogen from NADPH and CO2 used to build organic molecules such as glucose with ATP supplying the required energy
Which of the two photo systems absorbs light at the lower wavelengths
