On SlideShare. CO2, water, light, and chlorophyll are the raw materials for photosynthesis. Conceptual overview of light dependent reactions. 3. In photosynthesis, the light-dependent reactions take place on the thylakoid membranes.The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.The thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions. But, in case of light dependent reaction or light reaction of photosynthesis, it is most influenced by presence or absence of light. Energy travels through the electron transport chain, which pumps hydrogen ions into the thylakoid space. The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light- dependent reaction. Photosynthesis light reaction 1. In oxygenic photosynthesis, H 2 O serves as the electron donor to replace the reaction center electron, and oxygen is formed as a byproduct. Structure Of Chlorophyll. Now customize the name of a clipboard to store your clips. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. Photosynthesis Purpose: use energy from light to convert inorganic compounds into organic fuels that have stored potential energy in their carbon bonds Carbon dioxide + water glucose + oxygen CO2 + H2O C6H12O6 + O2 3. See our User Agreement and Privacy Policy. -Products are Trioses, Tetroses, Pentoses, Hexoses and Heptoses. The light reactions, the first stage of photosynthesis, convert light energy into chemical energy (ATP and NADPH). Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. When regarding the absorption spectrum of photosynthesis does it stand out that the efficiency of light of the wave length lambda > 680 nm decreases strongly although chlorophyll a displays an absorption in that area. Looks like you’ve clipped this slide to already. ARIF MAJID The overall formula for photosynthesis is: 6CO 2 + 12H 2 O → C 6 H 12 O 6 + 6O 2 + 6H 2 O. It happens in the STROMA of Chloroplast where the Carbon Dioxide absorbed by the leaves of the plant is converted into sugar. Water is split in the presence of light (called photolysis of water) to release O 2.Note In the case of photosynthesis, light energy is transformed into chemical energy, which autotrophs use to build carbohydrate molecules.

Reaction center chlorophylls P700 and P680. Like all energy, light can travel, change form, and be harnessed to do work. One can think of the light dependent reactions as a way to increase the free energy of the system and the light independent reactions as a way to convert that new free energy into the bonds of glucose. 6 CO2+6H20==>6O2+C6 H12 06 light. Photosynthesis 244 BIOLOGY Notes MODULE - 2 Forms and Functions of Plants and animals In photosynthesis, CO 2 is fixed (or reduced) to carbohydrates (glucose C 6H 12 O 6). ... Light reactions happens in the thylakoid membrane, and the calvin cycle happens in the stroma. A photon strikes photosystem II to initiate photosynthesis. CLASS: MSc.

Photosynthesis process (light and dark reactions) 1. - The reactions occur in thylakoids. It is easy to think of light as something that exists and allows living organisms, such as humans, to see, but light is a form of energy. • Light-dependent reaction • Light-independent reaction • Factors affecting Photosynthesis • Artificial Photosynthesis • Conclusion 3. This is the currently selected item. Once NADPH has been produced, the Calvin cycle proceeds as in oxygenic photosynthesis, turning CO 2 … While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions. See our Privacy Policy and User Agreement for details. module 4 ecosystem: life energy p h o t o s y n t h e s i s in the stroma the second stage of photosynthesis takes place called the calvin cycle - light independent reaction or dark reaction. - The reactions occur in stroma. The light-dependent reactions of photosynthesis convert solar energy into chemical energy, producing ATP and NADPH or NADH to temporarily store this energy. Title: Photosynthesis & Cellular Respiration Author: Julie Massanisso Last modified by: Bee Created Date: 9/27/2011 4:42:23 PM Document presentation format – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 7776e1-ZjFmZ State the membrane and the two fluid areas in the chloroplast where the light reactions occur. The light dependent reactions take place when the light excites a reaction center, which donates an electron to another molecule and starts the electron transport chain to produce ATP and NADPH.
