I. Introduction
Photosynthesis is the process that plants use to convert light energy into chemical energy. The reactants of photosynthesis include carbon dioxide (CO2), water (H2O), and light, and the products that are produced come out to be sugar in form of glucose (C6H12O6) and oxygen (O2). The reaction equation is as follows: 6CO2 + 6H20 + light -> C6H12O6 + 6O2. The variable being tested in this experiment is the affect of light on the rate of photosynthesis. Photosynthesis occurs in the chloroplast; the absorption of light takes place in the thylakoid membrane of the chloroplast and the sugar formation takes place in the stroma, which is the fluid within the chloroplast that surrounds the thylakoid. Photosynthesis occurs because this is the process that plants use to make its own fuel and energy. Photosynthesis occurs in plants to convert light to chemical energy to be used by other organism and also to release oxygen for humans in cellular respiration (Stegenga 24). The Hill reaction consists of transferring high-energy electron that comes from water to produce oxygen. It shows that the electrons are boosted to a higher energy level when light is absorbed and are moved around electron-acceptor molecules that are alternatively being reduced and oxidized. In this process NADP+ is reduced to NADPH, which is the source for the synthesis reaction (Stegenga 27). Reduction potential is the willingness of a molecule to be reduced or accept an electron. It is measured in volts and the more positive the number, the higher chance of the molecule to accept an electron and be reduced (Redox Potentials). This relates to our

    Photosynthesis is the process by which green plants, algae and some bacteria absorb light energy and use it to synthesize organic compounds. In green plants, photosynthesis occurs in chloroplasts, that contain the photosynthetic pigments. Photosynthesis occurs by slightly different processes in C3 and C4 plants. Factors which can affect this are the stomata. Plants can regulate the movements of water vapor, O2 and CO2 through the leaf surface. This is accomplished by opening and closing the stomata, usually found on the bottom…

    9-24-14 590550535305001st Introduction The process of photosynthesis occurs when six carbon dioxide molecules (CO2), six water molecules (H2O), and light energy are added together and result in glucose (C6H12O6) and six oxygen (O2) molecules. There are two stages to this process; light reactions and dark reactions. Light reactions start with chloroplast which absorbs the light. Inside the chloroplast are thylakoids that contain pigments which absorb certain wavelengths of light. Each cluster of pigments is called a photosystem. Photosystem I and II obtain some of the light’s energy. Light first enters chlorophyll A in photosystem II and the electrons inside become excited enough to leave it. Some of the electrons, which just left, enter a chain of reactions called the electron transport chain and it produces ATP. The electrons that couldn’t fit into the ETC move onto photosystem I. Those electrons then get excited by light energy and enter the ETC where they add a hydrogen atom to NADP to form NADPH.…

    Introduction: Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage, where energy from sunlight is captures in Photosystem 2 and then 1, the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP, by the ATP Synthase. The equation for this reaction is 6CO2 + 6H2O  C6H12O6+6O2 or, carbon dioxide +water sugars + oxygen . This reaction takes place on the thylakoid membrane of the chloroplast and uses energy from sunlight to produce compounds like ATP and NADPH. The second stage of photosynthesis is the Calvin Cycle, which takes place in the stoma of the chloroplast. This stage is light-independent or it does not need energy from sunlight. During this reaction ATP and NADPH from Stage 1are used to produce high energy sugars. The reaction is 3CO2 + 6NADPH + 5H2O + 9ATP  G3P + 2H+ + 6NADP+ + 9ADP + 8Pi . Additionally, the three limiting factors of photosynthesis are the light intensity, carbon dioxide concentration, and the temperature. Lastly, the items used in this particular experiment were baking soda to provide CO2, a light to excite the electrons in stage 1, distilled…

    In cellular respiration and photosynthesis, the reactants flow through pathways to become products in very different ways. Respiration is catabolic, breaking glucose down, while photosynthesis is an anabolic reaction, building glucose. When respiration breaks glucose down, energy is released in small increments. The released energy is used to synthesize ATP, NADH, and FADH2. The NADH and FADH2 go through oxidative phosphorylation to produce ATP and H2O. Photosynthesis uses light reactions to provide energy to build glucose. Inside the thylakoids, where the light reactions take place, there are two types of photosystems, II and I. Photosystem II utilizes light…

    Photosynthesis is a chemical process that converts the sunlight into a chemical energy that plants store for later. Without photosynthesis, the world as we know it would not exist. All the plants would die and so would a major food and oxygen source. During Photosynthesis water is sucked up through the roots up the stem and to the leaves. The leaves take in carbon dioxide and begin to absorb sunlight. these things combine to make glucose and oxygen. The plant then uses the glucose and oxygen is expelled through the stomata of the plant as a waste product. In The leaves there are a very special pigment called chlorophyll. Chlorophyll is responsible for the absorption of sunlight. Richard Martin Willstätter is the man responsible for studying these structures.…

    Light energy Light energy Background Information (Activity A): In photosynthesis, plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll, the primary photosynthetic pigment in chloroplasts. The chemical equation for photosynthesis is: 36 ATP + 6CO2 + 6H2O C6H12O6 + O2 (From: "LabBench for Lab 4." LabBench. PHS School, n.d.

    In plants, cells called chloroplasts collect energy from the sun and use water and carbon dioxide (photosynthesis) to make sugars.1 Light energy (called photons) hit single chlorophyll pigments in the cells of the plant leaves. 2 Photoautotrophs is the term used for plants that create energy out of sunlight. Plants that do not use the sun’s energy are called chemoautotrophs.3 For photosynthesis to begin a few conditions must be met; enough water must be available in a plant’s body, there should be direct sunlight on its leave, the leaves are green, and the leaves need to have access to carbon dioxide in the air.4 When the light energy has stimulated enough of the chlorophyll it is brought to a singular part of the chloroplast. The light energy combines with the water molecules, carbon dioxide molecules, and adenosine diphosphate and creates a chemical reaction.5 This chemical reaction produces oxygen and adenosine triphosphate, or ATP.6…
