AVU split into 5 sections

Question 1

issue and relevance

Answer 1

This report is going to investigate the effect enzymes have on the environment. Enzymes are relevant to the environment because they use up less energy and water, this has a positive impact on the environment because biological detergent is stronger than non biological detergent which means less energy and water will be used when using bio, ultimately helping the environment

Question 2

researching the issue - source 1

Answer 2

Information from source one shows that biological detergent, which includes enzymes can break down stains better than non bio, which doesn’t have enzymes. Biological is more effective and is better for the environment because bio can be operated at lower temperatures and use less energy, which will save money on fuel as water doesn’t need to be heated up so much

Question 3

researching the issue - source 2

Answer 3

In source two the graph shows that Sainsbury’s bio powder was the most effective but also shows that both bio and non bio powders did well in terms of killing bacteria. This means bio is overall best for th environment. Although bio was the more effective it can have it’s negative impacts for example it could cause mild reactions in those with sensitive skin, while non bio doesn’t have enzymes it can’t cause rashes but is slightly less effective.

Question 4

underlying biology

Answer 4

biological detergents has had a positive impact on the society/environment because it doesn’t need to operate at high temperatures, it works best at 40*c or below this saves money because the water doesn’t need to be heated so much, because of the enzymes breaking down protiens, it allows them to break. through tough stains at lower temperatures

biological detergent has also had a negative impact on society/the environment because the enzymes in biological detergent can cause allergic reactions like skin rashes or worsen eczema, making non bio safer for babies/young children

Question 5

conclusion

Answer 5

From my investigation I can conclude that biological detergent is better for the environment because you can wash clothes at lower temperatures and use less energy, source one supports this because it states that enzymes don’t need as much energy to operate as non bio. Linking back to the aim, Biological detergent is stronger because it contains enzymes and is more effective at breaking down stains but non bio will mostly rely on higher temperatures.
