Recommended: The importance of light on photosynthesis

“Photosynthesis is the process” in that plants, a few bacteria, and a few protist use light energy to produce sugar and then converts that sugar using cellular respiration into ATP. Then convert the unworkable light energy from the sun into “usable chemical energy” to use with chlorophyll (Farabee, “Photosynthesis”). When it talks about how NADPH is being reduced, it just means that there is a continued discharged of “electrons from water to” it (Farabee, “Photosynthesis”). Then that “energy is used in carbon fixation and at that time no NADH is made only ATP (Farabee, “Photosynthesis”). Sometimes the cell lacks ATP so it makes more or if their is no more NADP + to be reduced into NADPH (Farabee, “Photosynthesis”). When water is split in photosystem I and II to gain electrons (“Electron Transport in photosynthesis.”). A Proton Gradient is established with the help of the Electron Transport that then powers the production of ATP (“Electron Transport in photosynthesis.”) . Then stores energy in the reduced form of the coenzyme of NADPH (“Electron Transport in photosynthesis.”). The energy then is used in the Calvin Cycle to make sugar and other carbohydrates (“Electron Transport in photosynthesis.”). Light is a very important factor in photosynthesis.
Light influences Photosynthesis in number of ways. If the light is very intense the plant grows better than if the light has a low intensity. When the chloroplast has no light present, the chlorophyll wouldn't be the color green that we see. Also if their was no light present then there wouldn't be photosynthesis to take place. When the enzymes in photosynthesis become denatured their is a “loss of tertiary structure”(Salvucci et al) Heat puts stress on photosynthesis by loweri...

The chlorophyll absorbs light energy and enables it to be used by the plant for building up sugar. The overall effect is that energy is transferred from sunlight to sugar molecules.

  • Cellular Respiration And Photosynthesis Essay

    1028 Words  | 3 Pages

    So, after learning about what photosynthesis is and how it truly works is something that is remarkable and how plants are really the only living thing that uses this process. Such as photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sun light is absorbed through chloroplasts which contains chlorophyll or better known as the leaves of the plant. Sun light is what helps break down and rearranges the atoms of these two, which produces sugars (glucose, C6H12O6), and this is photosynthesis at its finest. With the photosynthesis process the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.). Photosynthesis is something that helps the plants to grow but it is also very beneficial to us for the fact that we need to breath oxygen to maintain our functions of life. Plants produce an abundant supply of energy that is stored because they are what I would like to call savers/hoarders. Plants store the extra energy that they produce into different things such as potatoes, carrots, and other different types of food in which we use to

    The substance that absorbs sunlight is chlorophyll, which is mainly contained in chloroplasts. This energy is used to convert carbon dioxide (CO2) and water into sugars. This conversion creates the waste product oxygen, which is used by humans for breathing. Without being able to photosynthesise plants will stop growing and die. In a plant growing in the dark the chlorophyll will slowly be destroyed causing them to use their food reserves.

    The Calvin cycle uses NADPH, ATP, and carbon as the reactants. In the light-dependent reactions, the electron released from water travels through the photosystems and the electron transport chain in the thylakoid membrane, then attaching to NAD+ to be carried to the Calvin cycle. When the electrons are taken from the water, the oxygen diffuses out and only hydrogen ions are left on the inside of the thylakoid, called the

    Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...

    Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.

  • The Effect of Light Intensity on the Rate of Photosynthesis in an Aquatic Plant

    The Effect of Light Intensity on the Rate of Photosynthesis in an Aquatic Plant Introduction The input variable I will be investigating is light, as light is just one of the 4 factors required in the green-plant process of photosynthesis. Photosynthesis is the process by which green-plants use sunlight, carbon dioxide, water & chlorophyll to produce their own food source. This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthesis. Light is the factor that is linked with chlorophyll, a green pigment stored in chloroplasts found in the palisade cells, in the upper layer of leaves.

    An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
