Photosynthesis

Unit 3

What is released by the cell to produce ATP

Energy in organic molecules

Photosynthesis

cells synthesizing organic mols from inroganic mol using energy

Photosynthesis Equation

Sun + 6H2O + 6CO2 —→ C6H1206 + 6O2

Photosynthesis occurs in the..

chloroplast

Chloroplast contains

chlorophyll

Thylakoids

light dependent reactions take place here

Stroma

light independent reactions take place here

Photolysis

separation of molecules by the action of light

The oxygen produced by the photolysis of water is___

Waste for the plant

Chromatography

technique which mixtures can be separated

How to calculate RF value

distance it travels/distance solvent travels

electromagnetic spectrum

all possible wavelengths of radiation

What spectrum of light can be seen

700-400 nm

pigment

 any substance that absorbs light

Most common type of accesory pigment…

carotenoids

Carotenoids mostly come in which to colors

yellow , orange

Main function of carotenoids

extend the range of light plants can absorb for photosynthesis

absorption spectrum

wavelength of light absorbed by each pigment

Action spectrum

amount of photosynthesis at each wavelenght

What are the 3 limiting factors of photosynthesis

Tempature, Light intensity, and CO2 concentration

How does temp limil photosynthesis

high temp can denature enzymes

how can light intensity limit photosynthesis

more chlorophyll is photo activated and then plateu

how can CO2 limit photosynthesis

More carbon and then plateu
