Every cell‚ whether it belongs to a plant‚ bacteria or a human‚ requires energy from varying food sources to survive. However‚ when cells break down food into its sugar components‚ i.e glucose‚ they cannot use the components directly because glucose holds a lot of energy it would be inefficient to use for reactions that don’t need a lot of energy. Imagine you want to buy pencils for $5 from a store that won’t give change‚ it is more economical to use a $5 or $10 bill than a $100‚ that way there is

Background Information: Spectrophotometry is a method that measures how much light is absorbed by using the electromagnetic spectrum. By seeing which colors are absorbed and which are reflected scientists can determine what a substance is without having to touch them. This is possible because each substance has a specific absorbance spectrum‚ meaning that the absorption spectrum of two different substances cannot be the same. Purpose/Hypothesis: 1. The purpose of the experiment was to determine
