• what is the photosynthesis equation ?

  carbon dioxide + water = glucose +oxygen
• what is a symbol equation for photosynthesis?


  6CO2 + 6H2O -> C6H12O6 + 6O2
• how do plants use glucose?

  Respiration, cellulose, amino acids, oils or fats, starch
• what factors affect the rate of photosynthesis?


  intensity of light, concentration of carbon dioxide and temperature
• how can I artificially create the ideal conditions for farming?


  Greenhouses, light, heaters, fertilisers
• what is respiration?


  The process of transferring energy from glucose which goes on in every cell
• name three examples of how organisms use energy transferred by respiration


  To build up larger molecules from smaller ones, allow animals muscles to contract, in mammals and birds energies to keep their body temperature steady in colder surroundings
• what is metabolism?


  Metabolism is the process by which the body converts food and drink into energy.
• what doesRespiration transfer energy to?


  All the reactions in the body that make molecules
• what is broken down in respiration?


  Glucose
• what is the sum of all the chemical reactions that happen in a cell or body called?


  Metabolism
• what is the word equation for aerobic respiration?


  Glucose + Oxygen -> Carbon Dioxide + Water + Energy
• what is the symbol equation for aerobic respiration?


  C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
• when is anaerobic respiration used?


  when there is not enough oxygen
• what is the word equation for anaerobic respiration in muscles cells?


  glucose -> Lactic acid
• what is the word equation for anaerobic respiration in plants and yeast cells?


  Glucose → Ethanol + Carbon Dioxide
