The transfer of substances containing carbon between organisms, and organisms and the environment this is a a2 biology synoptic essay, so i need to think of about 10 examples of this so far ive only got the basic ones, such as photosynthesis, respiration, and digestion. The transfer of substances containing carbon between organisms and between organisms and the environment june 2006question 4 the following topics from the specification contain material that could be relevant and used in the essay. The carbon cycle is just one of several recycling processes, but it may be the most important process since carbon is known to be a basic building block of life as the foundation atop which a huge family of chemical substances called organic substances are formed, carbon is the basis of carbohydrates, proteins, lipids, and nucleic acids—all. In addition, the atmosphere contains substances that are essential for life, including carbon, nitrogen, oxygen and hydrogen the hydrosphere - this consists of those parts of the earth system composed of water in its liquid, gaseous (vapour) and solid (ice) phases. Carbon is known as the most essential element for life, and it's the second most abundant — after oxygen — in the human body carbon paper was an early method of making copies, using a sheet of paper coated with wax and, originally, carbon soot.
However, the formulas for some ionic compounds containing polyatomic ions are not empirical formulas for example, the ionic compound sodium oxalate is comprised of na + and c 2 o 4 2− ions combined in a 2:1 ratio, and its formula is written as na 2 c 2 o 4. These molecular compounds (covalent compounds) result when atoms share, rather than transfer (gain or lose), electrons covalent bonding is an important and extensive concept in chemistry, and it will be treated in considerable detail in a later chapter of this text. Sakuma and colleagues (1984) measured the smoke components in mainstream and sidestream smoke and found that nitrogen-containing compounds were abundant in smoke from burley tobacco, whereas the non-nitrogen-containing compounds were more abundant in smoke from bright and oriental tobaccos. Carbon is found in many different compounds it is in the food you eat, the clothes you wear, the cosmetics you use and the gasoline that fuels your car in addition, carbon is a very special element because it plays a dominant role in the chemistry of life.
Particular substance reactions involving the transfer of a hydrogen ion, h+, a reactant (often containing carbon) reacts with oxygen o2. Organic chemistry - the study of carbon and its compounds the study of the chemistry of life inorganic chemistry - the study of compounds not-covered by organic chemistry the study of inorganic compounds or compounds which do not contain a c-h bond. The 5 carbon compound is then converted to a 4 carbon compound by the same decarboxylation and dehydrogenation process cells need to take in substances like glucose and oxygen and get rid of substances like urea and co2 glycolysis the link reaction oxygen and nitrogen. Carbon is contained in all organic compounds, which is why carbon is the second most abundant element in the body, accounting for about 18% of body mass carbon is found in proteins, carbohydrates, lipids, and nucleic acids. Since a compound contains two or more different elements, it also contains two or more different atoms, hence the simplest form of a compound is a molecule as an example, a molecule of water contains two hydrogen atoms and one oxygen atom, (written as h 2 o.
Chapter 4 carbon and the molecular diversity of life all organisms are composed mostly of chemical structures based on the element carbon. Orgainic chemistry is the study of chemicals that do not contain carbon study of the composition of substances determining the energy transfer when water boils. Carbon catalyst to saturate the alkene double bond of the the starting material scheme 2: the eight transfer-hydrogenation reactions performed in class however, this was not the only transfer-hydrogenation reaction run by the class. Organometallic chemistry — the study of chemical compounds containing bonds between carbon and a metal solid-state chemistry — the study of the synthesis, structure, and properties of solid materials.
• carbon dioxide in organisms and ecosystems • the transfer of substances containing carbon between organisms and between organisms and the environment. The carbon cycle all cells - whether animal, plant or bacteria - contain carbon, because they all contain proteins, fats and carbohydratesplant cell walls, for example, are made of cellulose - a. Photosynthesis converts these energy- depleted compounds (adp and nadp+) back to the high energy forms (atp and nadph) and the energy thus produced in this chemical form is utilized to drive the chemical reactions necessary for synthesis of sugars and other carbon containing compounds (eg, proteins, fats.
The transfer of substances containing carbon, between organisms and organisms and the environment has anyone got a sample answer to this essay question and could you post it on here. Nucleic acids are carbon compounds that store and transmit geneticinformation they include: deoxyribonucleic acid (dna) ribonucleic acid (messenger,transfer) (rna) proteins(in the case of. Ap chemistry-midterm review multiple choice identify the choice that best completes the statement or answers the question ____ 1 which response lists all of the following properties of sulfur that are physical properties and no other.
Heterocyclic compounds compounds classified as heterocyclic probably constitute the largest and most varied family of organic compounds after all, every carbocyclic compound, regardless of structure and functionality, may in principle be converted into a collection of heterocyclic analogs by replacing one or more of the ring carbon atoms with a different element. Combustion reactions occur when a compound, usually one containing carbon, combines with the oxygen gas in the air this process is commonly called burning heat is the most-useful product of most combustion reactions. Molecules, compounds, and chemical equations 31 hydrogen, is composed of water molecules that always contain 2 hydrogen atoms for carbon dioxide, meaning. When we burn these substances, carbon that has been stored for millions of years is released once again to the atmosphere in the form of carbon dioxide (co 2 ) the carbon cycle has a large effect on the function and well being of our planet.
