Is a process used by plants, algae, and some bacteria to convert light energy, usually from the sun into chemical energy in the form of glucose (sugar) These organism use carbon dioxide from the air and water from the so, and with the help of sunlight and chlorophyll, they produced glucose and oxygen as a by-product

A green pigment in plants

Sugar

Chemical Formula

6Co2 + 6H2 O + light energy > C6 H1 2 O6 + 6O2

2 phases of photosynthesis

• Photo - part of photosynthesis • Site - thylakoid membrane • NADP, ATP, By-product oxygen

ATP is produced by chemiosmosis using an enzymes called ATP Synthase

Convert energy to the chemical energy of ATP and NADPH

A form of electromagnetic energy or radiation

Smallest unit of light energy

Includes wavelength that drives photosynthesis

The light receptors that absord light of specific wavelength

Main photosynthetic pigment

Accessory pigments

Accessory pigment that absorb blue and green light and reflect yeow, orange or red

Absords violet, blue and red light while transmitting and reflecting green light

A key step in photosynthesis

When chlorophyll, a pigment in plant cell, absorb light (usually from sun), it absorb photons, which are packets of light energy. This causes electrons in the chlorophyll molecules to move to a higher energy level or "EXCITED" state

Step in the excitation process

The energy from the light excited electrons in the chlorophyll molecule

Once excited, the electrons gain energy and move to a higher energy orbit within the chlorophyll molecules

In photosynthesis, the excited electrons doesn't stay in the higher state for long

Is a process that uses the nergy stored in a proton gradient to produce ATP. It occurs within the Thylakoid membranes of chloroplast
