Words: 2038 (9 pages)

The effect of antibiotic concentration on bacterial growthIntroductionNull Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth.Scientific TheoryBacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci, rod shaped bacteria are called bacilli, spiral shaped bacteria are called spirilla…

Effect of concentration of H2O2 on the enzyme catalase


Words: 2435 (10 pages)

Enzymes such as Catalase are large protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. They are all specific as each enzyme just performs one particular reaction. In their globular structure, one or more polypeptide chains twist and fold, bringing together a small number of…
