The effect of ATP (adenosine triphosphate) on bioluminescence in fireflies.

Introduction

Adenosine triphosphate, also known as ATP, is the supply of energy found in every cell that we need in order to do essentially everything (Anonymous, 2008). It is an energy source for biochemical reactions such as muscle contraction, active transport, molecular synthesis, and in fireflies, also known as lightening bugs, bioluminescence (Biology Book). Bioluminescence is the process in which living organisms convert chemical energy into light (Branchini, 2008). In the fireflies case the reaction involves the enzyme luciferase which lights up a lantern-like mechanism under the tip the wings and attached to the end of the body of the firefly.

Results were observed and recorded.
At station 3, the control Petri dish was left alone and the experimental Petri dish was heated in a hot water bath for 60 second using a clamp to hold it in place. The experimental Petri dish was removed from the hot water bath. Two drops of ATP solution was added with a pipette to both the control and the experimental Petri dish. Results were recorded. At station 4 a pipette was used to add two drops of ATP to both the experimental and controlled Petri dishes. The pipette was used to deliver several drops of sodium chloride solution to the experimental Petri dish. Results were observed and recorded.

Results In station 1 when the acid was added to the experimental Petri dish the bioluminescence of the powdered firefly lantern started to dim and once the base was added the lantern began to brighten up again. The controlled Petri dish remained bright during all four of the experiments. The results are as shown in Table 1. In station 2 after the experimental Petri dish was taken out of the fridge and ATP was added the powdered firefly lantern did glow but at a very dim level. The results are as shown in Table 1. In station 3 after the experimental Petri dish was taken out of the hot water bath and two drops of ATP were added no bioluminescence reaction occurred at all in the powdered firefly lantern and
