A very thin slice is removed from a peanut and treated with a drop of Biuret reagent and then placed on a brown paper bag. A translucent spot was left behind on the brown paper bag and there are blue-violet spots on the peanut. What conclusions can you draw from this examination?

Asolution of an enzyme and a substrate was placed in a water bath and the temperature of the reaction was raised gradually. the graph shown was plotted at the end of the experiment. what can be concluded from the graph? a) temperature has no effect on the activity of the enzyme. b) the effect of temperature on the enzyme is unpredictable. c) the enzyme shows increased activity up to a certain temperature. d) the activity of the enzyme is inversely proportional to the temperature.
