Transcript of Biology Assignment
A Nucleic acid that contains the sugar deoxyribose forms the main constituent of the cell wall in most plants, and is important in the manufacture of numerous products, such as paper, textiles, and explosives Condensation A chemical reaction in which water or another simple substance is released by the combination of two or more molecules Elements A substance composed of atoms having an identical number of protons in each nucleus Enzyme Any of numerous proteins or conjugated proteins produced by living organisms and functioning as biochemical catalysts Glucose A monosaccharide sugar, occurring widely in most plant and animal tissue. It is the principal circulating sugar in the blood and the major energy source of the body Hemoglobin an iron-containing protein in red blood cells that transports oxygen from the lungs to the tissues of the body. Hormone Living systems are made up of complex molecules that consist mostly of a few elements, especially carbon, hydrogen oxygen nitrogen and phosphorus. Substance made in one half of an organism that affects the other half of the same individval. Hydrogen Hydrolysis Inorganic molecule Lipids Macromolecue made from carbon and hydrogen atoms
Ex: Fats,waxes and oils M
e Molecules There are four major categories of organic molecules that make up living systems: carbohydrates, fats, proteins, and nucleic acids. Carbon is the backbone of all living organisms. The simplest unit of a chemical compound that can exist, consisting of two or more atoms held together by chemical bonds A chemical reaction in which a compound reacts with water to produce other compounds We would all die because we need all of them to live. A flammable colourless gas that is the lightest and most abundant element in the universe. Any very large molecule, such as protein or synthetic polymer Carbohydrates create and give the body energy. Lipids main purpose is to store energy and then release it when the body needs it. Proteins purpose is to build muscle, fight disease, and control the rate of reactions. Nucleic acids are found in DNA and RNA and it carries your genetic information. Carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Carbohydrates, lipids, proteins, and nucleic acids. Both living and nonliving things are composed of compounds, which are themselves made up of elements joined by energy-containing bonds, such as those in ATP Lipids contain high energy bonds because they have a lot of carbon in them which can form unlimited bonds. All living or once-living organisms are composed of carbohydrates, lipids, proteins and nucleic acids. Carbohydrates and lipids contain many carbon-hydrogen bonds that also store energy. All living or once living organisms are composed of carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates and lipids contain many carbon-hydrogen bonds that also store energy. However, that energy must be transferred to ATP to be usable by the cell. Non living thing without carbon Monomer Small unit that can join together with other small units to form polymers Monosaccharide Single sugar molecue Nitrogen A colourless odourless relatively unreactive gaseous element that forms 78% of the air, occurs in many compounds and is an essential constituent of proteins and nucleic acids Nucleic Acids Any of a group of very large polymeric nucleotides that constitute the genetic material of living cells and viruses and that code for the amino acid sequences of proteins Organic molecule Any compound of carbon and another element Oxygen A colourless odourless highly reactive gaseous:the most abundant in the earth's crust Phospholipid Any of a group of compounds composed of fatty acids, phosphoric acid, and a nitrogenous base Phosphorus An allotropic nonmettalic element occurring in phosphates and living matter Polymer A naturally occurring or synthetic compound, such as starch or perspex, that has large molecules made up of many relatively simple repeated units Polysaccharide Any one of a class of carbohydrates whose molecules contain linked monosaccharide units Protiens Any of a large group of nitrogenous organic compounds that are essential constituents of living cells R N A A long linear polymer of nucleotides found i n the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes Starch A carbohydrate that is the chief form of stored energy in plants, and potatoes What are the six most common element in organic molecules?
