Part 1 Photosynthesis

jtang: 1.1 Overview of Photosynthesis 1.1.1 Photosynthesis is a biological oxidation-reduction process Reaction 1.1: Photosynthesis CO2+2H2A-(CH20)+2A+H2O

1.1 Overview of Photosynthesis 1.1.1 Photosynthesis is a biological oxidation-reduction process. Reaction 1.1: Photosynthesis CO2+2H2A→(CH2O)+2A+H2O ljtang:

Reaction. 2: Oxygenic Phototsynthesis CO2+2H20-(CH2O)+O2+H20

Reaction1.2: Oxygenic Phototsynthesis CO2+2H2O→(CH2O)+O2+H20

Reaction 1.3: Photosynthetic sulfur reduction ●CO2+2HA→→(CH2O)+2S+H2O

Reaction1.3:Photosynthetic sulfur reduction ⚫ CO2+2H2A→(CH2O)+2S+H2O

1.1.2 In photosynthetic eukaryotes, photosynthesis takes place in the chloroplast, a specialized organelle Chloroplast s08000000090808 Inner envelope 0008000 Outer Stroma- envelope Stroma Granal exposed thylakoids thylakoids

1.1.2 In photosynthetic eukaryotes, photosynthesis takes place in the chloroplast, a specialized organelle

Chloroplast, a double-membrane system, consist of an out envelope and inner envelope. The internal membrane system, known as the thylakoids contains granal thylakoids and stroma thylakoids The thylakoid membranes are all interconnected and enclose an internal space, the lumen

1.1.3 Photosynthesis requires the coordination of two phases: light reactions and carbon-linked reactions CATP Light reactions Carbon reactions (Thylakoid membranes) NADP一一 (Stromal enzymes) HO CO CHO

1.1.3 Photosynthesis requires the coordination of two phases: light reactions and carbon-linked reactions

Light reactions: produce O2. ATP and NADPh Carbon reduction cycle: reduce CO2 to carbohydrate on consuming th atP and NADPH The conception that water oxidation and co2 reduction were ne obligately linked was first advanced in 1930s by robert hill Reaction 1. 4: Hill Reaction 2H2O+2A02+2H2A

Light reactions: produce O2, ATP, and NADPH. Carbon reduction cycle: reduce CO2 to carbohydrate on consuming the ATP and NADPH. The conception that water oxidation and CO2 reduction were not obligately linked was first advanced in 1930s by Robert Hill . Reaction 1.4: Hill Reaction 2H2O+2A→O2+2H2A
