Banana Peel as an Alternative for a Shoe Polish

I. Rationale Banana is a staple starch for many tropical populations.Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet, and texture from firm to mushy. Bananas are an excellent source of vitamin B6 and contain moderate amounts of vitamin C, manganese and dietary fiber. There many uses of the “banana”; banana sap from the pseudostem, peelings or flesh may be sufficiently sticky for adhesive uses, the large leaves may be used as umbrellas and…

Fundamentals of Cell Biology

The name of enzyme involved in this experiment is salivary amylase, which presents in our saliva. Salivary amylase catalyses the breakdown of complex sugar, such as starch, into a simple sugar, such as glucose. In this experiment, the optimum temperature for salivary amylase to function is 37˚C. Above the optimum temperature, the kinetic energy in the substrate and enzyme increases. The number of collisions between substrate and enzyme also increases, but the formation of enzyme-substrate complex decreases. This is because…

Yeast Fermentation

The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three, along with glucose and galactose, dietary monosaccharides that are directly absorbed into the bloodstream during digestion. Materials: 2% yeast…

Zachary’s Story

A) An ulcer starts by eroding the mucosa of the GI tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the submucosa and then the muscularis? Some of the ingested and secreted may not be absorbed correctly and may seep lumen if the mucosa layer is no longer functional. The functions that may be compromised if the ulcer eats through the…

Enzyme Activities

The term “photosynthesis” is so called because it synthetic process driven by light. Many studies have been carried on the light spectrum quality, intensity, wavelength and their combinations thereof on the rates of photosynthesis. Different importances have been attributed to different factors. But light and carbon dioxide are the most important paramers for active photosynthesis. In the present studied effect of light intensities (low and high) were investigated. It was found that Light is crucial for photosynthesis. It was also…

Biology_ Experiment

Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC, which is the body temperature, where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range…

Effect of Varying Temperatures on Enzymatic Activity

Abstract This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch and placing the solution of amylase and starch in various temperatures of water. After a certain amount of time- different amount of time needs to be used in order to have reliable results- iodine is added in a well on spot plates, then two drops of the mixture of amylase-starch is…

Factors Affecting the Rate of Enzyme Activity

The Purpose of doing this experiment is “how factors affect on the rate of enzyme activity.” “We examine the affects of enzyme activity when exposing enzymes to different substrates, PH and temperature. In this experiment a type of enzyme called Peroxides has been used. Peroxidase is the enzymes are found in living organism so, it can be founded in both liver and potato. For measuring the rate of enzyme activity in each experiment the height of the frothy foam column…

Biochemical Basis of Hfi

1. 2 Important Features of Enzymes Enzymes are proteins used in chemical reactions. In the reactions, enzymes act as catalysts. They function to speed up chemical reactions without using the enzymes themselves. The catalysts are neither the reactor nor the product. The first feature discussed in the text is the energy of the reaction. Catalysts will not change the energy of any reaction. For example, a non-catalyzed reaction and a catalyst reaction will both have the same equilibrium. Another feature…
