Biology A - Assignment 1: Cell Membranes and Temperature Background Theory Beetroot contains betalain pigments within it’s vacuole‚ which gives it it’s purple-red colour‚ it’s this pigment which leaks out as the beetroot is heated and the cells membrane begins to break down. The practicals aim is to show the effect of temperature on the cell membrane by observing the colour change of the water the beetroot was placed in. The cell membrane is important as it controls the substances enters and

Method: The placebo controlled experiment design can be helpful in this study. In order to determine the effect of caffeinated energy drink‚ the total of twenty athletes will volunteer to participate in it. All the participants will be divided into two groups; ten will drink caffeinated energy drink and other ten will ingest placebo (no caffeine content). The drinks will be served in an opaque bottle to avoid its identification and to make sure that player drink beverages in it entirely. Both the

I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then
