random mixing of particles in a solution occurs because of the particle ’s kinetic energy “(Allen C. 2006)‚ and is subjected to detect the presence of each of the substances given in the biochemical testing‚ the increase in temperature‚ and different reagent used are some aspect that could cause the difference of diffusion in certain solution. It was clear that the protocols Glucose‚ Albumin‚ NaCl‚ and Starch would be tested positive in the cytoplasm solution through diffusion‚ meaning they are present

The color caused by the reaction of peptide bonds in the protons or peptides. The presences of free amino acids will not give you the violet color.

Paper Spot test‚ one would have had to apply the substance on a cardboard like paper. If it looked oily it was the biomolecule called lipid. The result of test one was it stayed the same‚ it did not turn oily and was clear. Next was the test called Biuret test‚ this was to test if it was a protein. If it was a positive control it would break down into 2 colors of maroon-brownish. While substance 1 stayed clear with a blue-green tint. Concluding that the substance is definitely not a protein.

organisms.html) A few experiments were performed to test for the presence of the different types of macromolecules of various solutions. The iodine tested for starch and glycogen‚ Benedict’s test tested for reducing sugars for carbohydrates and biuret test was performed to test for proteins. It is necessary to understand how important controls are in a lab experiment. A control is where all of the experimental variables can be controlled and monitored. Results are determined by comparing these
