different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen‚ where a higher concentration of inhibitor will yield less oxygen‚ resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed that less gas was produced as the concentration of the inhibitor rose. This Is because more enzymes were inhibited‚ and so less active sites

The uses of plants in developing and producing vaccines For thousands of years‚ society has been brought to the brink of disaster thanks to the spread of resilient diseases and the plague of hardy viruses. However‚ humans have been aware for just as long of medicinal defence mechanisms against these ailments. The ancient Egyptians and Romans‚ as well as the primitive islander and Aboriginal communities‚ knew that certain herbaceous matter could help heal the wounded and sick. In more recent times

The Determination of the Effect of pH on Amylase Activity Grace Chung Abstract: Amylase is an important enzyme in the human body as it allows for the consumption of starch by breaking the polysaccharide down into maltose units. All enzymes‚ including amylase‚ function best at a certain optimal pH. Therefore‚ in this experiment‚ the effect of different pHs on the reaction rate of amylase is studied. It was hypothesized that the amylase-starch reaction would proceed fastest at a pH closest to

environments that would be normally inhospitable. Genetically modifying crops improve their cold tolerance. Unexpected frost can destroy sensitive seedlings. An antifreeze gene from cold water fish has been introduced into plants such as tobacco and potato and strawberries. With this antifreeze gene‚ these plants are able to tolerate cold temperatures that normally would kill unmodified seedlings. Because the plants can survive in harsher conditions that they previously couldn’t have‚ the farmers are

In conclusion‚ the original sample was used to collect different amounts of fraction. The original sample was Spirulina‚ which was spun down in a centrifuge before using. This process helps to separate the proteins from the tissues. Table 1 shows the amount of fraction collected from each sample. Based off the collected fractions‚ there is a larger quantity of yellow fraction present than the blue fraction. The yellow fraction remained in the filter for a longer period of time than the blue fraction

EXTRACTION OF DNA FROM ONIONS ABSTRACT The purpose of the experiment was to experience firsthand the isolation of DNA form a plant tissue without destroying its structure and sequence. A white onion was used for the experiment. After several processes‚ DNA isolate was the visible result. Different chemical tests were performed on the DNA isolate‚ namely: Dische Test‚ Murexide Test‚ Wheeler-Johnson test and Test for Phosphate. Visible results were then noted.
