As mentioned before‚ browning in bananas is an enzymatic process where enzymes such as polyphenol oxidase serve as catalysts in the oxidation of several phenolic compounds. In this experiment however‚ the only reaction being tested is the oxidation of catechol (a diphenol) by the enzyme catalyst catechol oxidase or polyphenol oxidase‚ which initiates a chain of reactions and eventually triggers the formation of brown pigments known as catechol-melanins. Catechol‚ also called 1‚2-dihydroxybenzene

Overview In the cell‚ chemical reactions take place to help release and convert energy. For example‚ sugars are converted to amino acids to make proteins‚ but in digestion‚ proteins are broken down into monomers of amino acid which then are converted into sugars. The process of cellular respiration is an example of chemical reactions. Throughout the chapter‚ the cell’s metabolism will be examined to understand how it controls the chemical reactions that take place in the cell. Section 6.1 -

It cannot cleaves the peptide bonds at the terminals. Endopeptidase is unable to break peptides into monomers. 3. Ang (1-9) causes vasodilation by increasing nitric oxide. Also‚ decreases the fibrosis and hypertrophy. But‚ Ang (1-7) decreases the collagen synthesis‚ fibroblast proliferation and cardiomyopathy. However‚ Ang (1-7) increases the left ventricular

How ethical is McDonald’s and which stakeholders benefit the most and who are neglected McDonald’s is a globally well-known restaurant. At first glance‚ it seems to be a brilliant company‚ but does it mean that the way it works is in accordance with ethics? The words ‘business ethics’ are defined as ‘principles and standards that guide behavior in the world of business’ (Ferrell and Fraedrich et al.‚ 2002‚ p.6). This essay will discuss the extent of McDonald’s ethics as well as the stakeholders
