MetabolismAnabolism+catabolism. the chemical processes that occur within a living organism in order to maintain life. Enzymatic Reactions inside a living organism CarbonCarbon is an element with the atomic number 6, meaning it has four electrons in its outer shell. These electrons can form covalent bonds with carbon atoms or atoms of other elements. This allows a diversity of stable compounds to exist. LipidsA diverse group of Carbon containing macromolecules made up of carbon, hydroge...

Biology AQA A level questions + answers - Exchange, energy transfers + response A 2g sample of biomass was fully combusted in a calorimeter. The volume of water in the calorimeter was 100cm^3. The increase in temperature recorded was 15.7oC. 4.18J of energy are needed to increase the temperature of 1cm^3 of water by 1oC. Use this information to calculate the heat energy released in KJ per g of biomass. Show your working. (2 marks) - correct answears100cm^3/1000 = 0.1kg 0.1x4.18x15.7...
