Inorganic ions are charged particles that do not contain carbon atoms bonded together. While organisms are mainly built from carbon-containing molecules, their functions rely on inorganic ions such as nitrate, hydrogen and calcium. This essay will detail some of the roles of specific ions and describe how animals, plants and bacteria use them. Productivity in an ecosystem in the soil is limited in part by the availability of fixed nitrogen in the soil. Nitrogen fixing bacteria in the roots of leguminous plants reduce atmospheric nitrogen to ammonium using ATP and reduced NAD.
Both ATP and NADPH are responsible for the reduction of glycerate-3-phosphate into triose phosphate, which is converted into many useful organic compounds like carbohydrates, mainly glucose. Although glucose can be used as a direct energy source by plants, it cannot be used directly by animal cells as a source of energy. Instead, cells use ATP as their immediate source of energy. The conversion
The Impact Humans Has On the Ecosystem Shanty DePriest Everest University Online EVS 1001-44 October 26, 2012 The Impact Humans Has On the Ecosystem There are three Cycles in the Ecosystem that are impacted by Humans. They are the Carbon Cycle, the Phosphorus Cycle, and the Nitrogen Cycle. First cycle that human has a very significant impact on is the Carbon Cycle. The Carbon Cycle is the circulation of carbon between living organisms and their surroundings. For instance Carbon Dioxide from the atmosphere is synthesized by plants, which is ingested and metabolized by animals, which is converted to Carbon Dioxide during respiration and decay.
According to Hopkins (2006), photosynthesis is the process by which green plants and certain organisms transform itself from light energy into chemical energy. As a straight forward chemical reaction in which carbon dioxide comes from the air, along with the midair and water from the soil, photosynthesis conglomerates to produce what is known as carbohydrate (p. 6). Solar Energy produced by photosynthesis, stores itself in a chemical bond of a carbohydrate molecule. Sugar known as glucose is then formed which becomes convenient both by way of energy to be stored for later use in tissues or by way of carbon to be used for cells (p.7). Hopkins, w. G. (2006).
CnH2nOn + nO2 + ADP + Phosphate (+ oxidizing agent and energy from photon [through electrochemical gradient]) → ATP + nCO2 + nH2O Function Carbohydrates play a variety of extensive roles in all forms of life: Carbohydrates are initially synthesized in plants from a complex series of reactions involving photosynthesis. Store energy in the form of starch (photosynthesis in plants) or glycogen (in animals and humans). Provide energy through metabolism pathways and cycles. Supply carbon for synthesis of other compounds. Form structural components in cells and tissues.
The Action Spectrum and the Absorption Spectrum Introduction: The purpose of this experiment is to learn the rates of photosynthesis under different lights, and the absorbance of photosynthetic pigments in spinach extract. “There would be no biology without photosynthesis. Plant biomass is the food and fuel for all animals. Plants are the primary producers. These amazing organisms are capable of capturing the energy of sunlight and fixing it in the form of potential chemical energy in organic compounds.” (Measuring the rate of photosynthesis) “Light is one of the main factors that affects the rate of photosynthesis, which literally means using light to create something new.” (What Are Three Factors That Affect the Rate Which Photosynthesis Occurs?)
Acetyl-CoA is transported within the cell to the mitochondrion, a specialized organelle where acetyl-CoA converts into ATP. Aerobic cellular respiration is a more efficient process producing 38 molecules of ATP compared to the anaerobic process that produces 2 ATP molecules. This sequence of reactions also creates the by-products of water and carbon dioxide (CO2). The by-product carbon dioxide was the compound measured for this experiment. As carbon dioxide is released into the water through the respiration of the crayfish it is converted into carbonic acid shown below.
Some of the dissolved carbon dioxide remains in the water, the warmer the water the less carbon dioxide remains in the water. Some carbon dioxide is used by algae and phytoplankton through the process of photosynthesis. In the natural carbon cycle, there are two main processes which occur: * Photosynthesis = plants use carbon dioxide and produce oxygen. * Metabolism = oxygen is used and carbon dioxide is a product Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, coal, or natural gas. Fossil Fuels were formed very long ago from plant or animal remains that were buried, compressed, and transformed into oil, coal, or natural gas.
Photosynthesis is the process when plants and some bacteria use the sun lights energy to produce glucose from carbon dioxide and water. carbon dioxide + water- sunlight- glucose + oxygen Energy in the form of light is the definition of electromagnetic energy. Any visible light like light bulbs, electromagnetic energy can take the form of it. The energy is being absorbed to break bonds making the process endothermic. When energy is being released making new bonds formed is called the exothermic process.
Comparing the Growth of Pea Plants Grown in the Light and in the Dark Aim: To compare the vertical growth and weight gain of pea plants grown in the light and in the dark. Background Knowledge: Photosynthesis forms the basis for this experiment. This is the process by which a plant makes food for itself from the raw materials around it. The energy needed for photosynthesis comes from sunlight, which is the variable for this experiment. The substance that absorbs sunlight is chlorophyll, which is mainly contained in chloroplasts.
