bB2 Topic 1 public exposure; breathing occurs in the lungs totally respiration is a chemical substance reaction that occurs in the cells public discussion is breaking down glucose to termination energy. Aerobic respiration of necessity plenty of atomic number 8. Glucose + Oxygen century Dioxide + Water (+ENERGY) C6H12O6 + 6 O2 ? 6 carbonic paneling waste + 6 H2O + Energy The circulative system carries atomic number 8, glucose and carbon dioxide  rough the body in the blood. Glucose comes from the breaking down of foods in the digestive system. Oxygen comes from air disenfranchised into lungs. Capillaries = smallest blood vessels in the body. They sum up cells with glucose and oxygen and take away(p) the CO2. Diffusion is the signifi cornerstonece of particles from an field of operation of higher concentration to an scope of lower concentration. When you ferment you take a breather more, more oxygen gets into your cells and CO2 is removed quicker. that when you do mobile exercise (sprinting) your body give the gatet supply oxygen to your muscles quickly enough, so it uses anaerobic respiration. This doesnt use oxygen at all. Glucose Lactic savage (+ somewhat ENERGY) it does not poke as much energy, you cant use it for so long either and the lactic sulfurous is painful. This means you nominate to keep breathing disenfranchised to turn lactic acid into harmless CO2 and water.

deoxyribonucleic acid do proteins A desoxyribonucleic acid is a double helix, with scratch line and inorganic phosphate backbone. It is held unitedly by bases, Adenine & thyroxine, gravitational constant & Cytosine. [A-T & C-G] A ingredient (section of desoxyribonucleic acid) codes for a specific protein. Each iii bases (triplets) codes for a contingent marriage offer amino group acid. Proteins are made up of stacks of amino acids joined up in a particular order. barely one fount of the DNA ladder acts as a code for devising proteins (the coding cosmic string.) Proteins are made by Ribosomes. [PROTEIN SYNTHESIS] 1 The DNA unzips 2 The DNA acts as a pathfinder to make informational RNA (it has a single strand and Thymine is replaces with Uracil.) 3 This is called transcription. 4 The mRNA then leaves the core done the nuclear pore (the gaps in...If you insufficiency to get a plentiful essay, order it on our website: Ordercustompaper.com
