Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
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
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).
In plants the way they get there energy is through sun light where they have process called photosynthesis where they produce and release oxygen in the air. Photosynthesis requires direct sunlight, carbon-dioxide, and water. In this process of photosynthesis, plants decompose the molecules of hydrogen and carbon dioxide into hydrogen, then carbon and oxygen produces glucose which forms their source of energy, food and growth. Solar cells similar to this process get sunlight where light in the form of photons hits the solar cell and are absorbed by semiconducting materials such as silicon. Negative electrons are break free from their atoms, causing them with an electric potential difference.
During the day, carbon dioxide is released from the organic acids made the night before to become incorporated into sugar in the chloroplasts. C4 plants are plants that preface the Calvin cycle with reactions that incorporate carbon dioxide into a four-carbon compound, the end product which supplies carbon dioxide for the Calvin cycle. In C4 plants, there are two types of photosynthetic cells which are called bundle-sheath cells and mesophyll cells. In mesophyll cells, the enzyme PEP carboxylase adds carbon dioxide to PEP. A four-carbon compound conveys the atoms of the carbon dioxide into a bundle-sheath by way of plasmodesmata.
Glucose is split into two molecules called pyruvate and two ATP molecules are generated per molecule of glucose as well as two molecules of NADH. Also Glucose takes place in the cytoplasm of the cell. Glycolysis can occur with or without oxygen. Without oxygen it is called fermentation with oxygen it is the first stage of the cellular respiration. • What is the role of the citric acid cycle?
Form structural components in cells and tissues. Photosynthesis is a complex series of reactions carried out by algae, phytoplankton, and the leaves in plants, which utilize the energy from the sun. The simplified version of this chemical reaction is to utilize carbon dioxide molecules from the air and water molecules and the energy from the sun to produce a simple sugar such as glucose and oxygen molecules as a
P4- Explain the Physiology of two named body systems in relation to energy metabolism in the body. In this essay I am going to be explaining how energy is made in the body and two body systems that help to produce this energy. “The metabolic systems are responsible for the chemical reactions within the body. These reactions are involved in the maintenance of the living organism and may be involved in reactions that break compounds down catabolic reactions or reactions which build compounds up anabolic reactions”. (King R 2012) They all require energy to work.
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.
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. This energy is used to convert carbon dioxide (CO2) and water into sugars. This conversion creates the
