The factors which influence the process of photosynthesis are light, water, CO2 and Chlorophyll of the leaf. Ask questions, doubts, problems and we will help you. Explain how air pollution may have an effect on photosynthesis and the balance of nature. How is this access mechanism different in RAID level 5? It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. ; () Authors: Muller, A Publication Date: Tue Jan 01 00:00:00 EST 1963 OSTI Identifier: 5054671 Resource Type: Journal Article Journal Name: Proc. Answer: Photosynthesis is a method of transforming light energy into chemical energy by phototrophs, which is later used to fuel cell functions. 0 Ans Give the schematic representation of photorespiration. Sign in. Carbon dioxide is obtained through tiny pores in plant leaves called stomata. The model provided good simulations for rates of photosynthesis and pool sizes of intermediates under varying light, CO(2) and O(2). 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. Assimilatory powers (ATP and NADPH 2) are mainly produced in this light reaction. Explain the access mechanism of a Magnetic disk. Light Reaction. Chlorophyll absorbs the light energy from the sun to … ... To explain the mechanism of ATP synthesis, binding change or flip-flop model is one of the widely accepted models. asked May 26, 2017 in Biology by Kundan kumar (51.1k points) life processes; Share It On Facebook Twitter Email. Roy. Table of Content: Light Reaction. answered May 26, 2017 by Vikash Kumar (254k points) selected Jun 5, 2017 by Kundan kumar . Ask questions, doubts, problems and we will help you. C 4 carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. Algae also use photosynthesis to turn solar energy into chemical energy. In the process of photosynthesis, the carbohydrates are synthesized from CO2 & H2O in presence of sunlight & chlorophyll and O2 is released. Mechanism of Opening and Closing of Stomata MECHANISM OF TRANSPIRATION Water is absorbed by the roots and is conducted upwards through the xylem vessels. 0 Ans Explain Blackman’s law of limiting factors. Best Answer. Factors affecting photosynthesis Rate of photosynthesis depends on many factors like light, carbon dioxide, water and chlorophyll. Since photosynthesis requires carbon dioxide, water, and sunlight, all of these substances must be obtained by or transported to the leaves. Share with your friends. Explain the mechanism of photosynthesis. a) Light: Visible spectrum of the sunlight ranges from 380 to 750 nanometres in wavelength. Photosynthesis is essentially the only mechanism of energy input in the living world. Explain the effect of light and temperature on the rate of photosynthesis. X. The chemical reaction for photosynthesis is 6 CO2 + 12 H2O + light energy -> C6H12O6 + 6 CO2 + 6 H20 If the input water is labeled with a radioactive isotope of oxygen, 180, then the oxygen gas released as the reaction proceeds is also labeled with 180. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Explain the mechanism of photosynthesis?. However, human activities also produce molecules like carbon monoxide and methane, both of which are also greenhouse gases. Quantum Yield. There is one difference though, here the proton accumulation is towards the inside of the membrane, i.e., in the lumen. Photosynthesis in Plants . In the atmosphere, many carbon-based molecules serve as greenhouse gases, which reflect heat back onto the Earth. C3 Photosynthesis. But if the process of photosynthesis is viewed as a game, we see that a match fixing takes place between the factors of photosynthesis to produce the end product called the glucose/ starch, which gives life to the world of living organisms. The process of photosynthesis is considered as an oxidation-reduction reaction activated by light absorbed by chlorophyll or certain other substances (e.g., phycocyanin, fucoxanthol), resulting in the evolution of oxygen from water and in the formation of reduced carbon compounds (e.g., carbohydrate) from carbon dioxide. Quality of the light also influences the rate of photosynthesis. 150 views. The sugars are used by the cell as energy, and to build other kinds of molecules. Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. A basic novelty of the model is coupling of NADPH production via NADP-ME with ATP production and regulation of the C(3) cycle in bundle sheath chloroplasts. Chloroplasts are the actual sites for photosynthesis. Light reaction occurs in grana fraction of chloroplast and in this reaction are included those activities, which are dependent on light. 2.85K views Ahmed asked August 14, 2017 Plant Physiology Photosynthesis. In photosynthesis, the inorganic compounds of carbon dioxide, water, and sunlight are used by photoautotrophs to produce glucose, oxygen, and water. This time these are membranes of the thylakoid. ADVERTISEMENTS: Photosynthesis: The Process Of Photosynthesis Explained (With Diagrams)! Chlorophyll the green-coloured pigment present in plants is responsible for performing photosynthesis because it has the ability to absorb sunlight and convert it into food. The results in this study further explained how the photosynthesis reaction was decreased by these flavonoids. In plants, photosynthesis occurs mainly within the leaves. (a) State the meaning of photosynthesis based on the schematic diagram. explain the mechanism of photosynthesis? The chemiosmotic hypothesis has been put forward by Peter Mitchell (1961) to explain the mechanism. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. Within the context of photosynthesis and respiration – this is mainly carbon dioxide. - 8783528 Criminology as a science its focused on how criminal behaviors develop and interact to the environment, therefore it should utilize other science like … Like in respiration, in photosynthesis too, ATP synthesis is linked to development of a proton gradient across a membrane. ← Prev Question Next Question → +1 vote .
