Photosynthesis Chapter 8

6CO2+6H2O+light energy=C6H12O6+6O2

Through the stomata

Chloroplast pigments, they become excited and send the electron to the electron acceptor

Redox reaction, reverses direction of electron flow in respiration

Water is oxidized into O2 and CO2 is reduced to C6H12O6 (glucose).

Double membrane organelle where photosynthesis occurs and creates glucose/oxygen

Absorb light, chloroplast.

Thylakoid membrane

Electromagnetic energy (electromagnetic radiation)

Wavelength is the distance between crests of electromagnetic waves

The entire range of wavelengths of electromagnetic radiation

380nm to 750nm

Photons, Shorter the wavelength of light, the greater the energy per photon.

Substances that absorb visible light, different pigments absorb different wavelengths

Violet blue and Red light

Chlorophyll b and group of pigments called carotenoids

The oxidation of H2O

Light reactions and The Calvin cycle

A particle, photon

Molecule absorbs a photon, the molecules electrons are elevated to an orbital with more potential energy. Ground state to excited state.

Structures located in the thylakoid membrane that contain several organized chlorophyll molecules. Helps create ATP and NADPH

Pigment molecules that absorb and transfer sun energy to the reaction centers

Photosystem 1, reaction center P700 and Photosystem 2, reaction center P680

Work together to use light energy to generate ATP and NADPH

Cyclic and Linear (noncyclic)

Predominant route, produces both ATP and NADPH, Similar to Oxidative phosphorylation and contains the process of Chemiosmosis.
