Unit 1 Questions. Total: 16 marks 1. How many electrons does Mg2+ have? (1 mark) 10 electrons 2. Given that the half-life of the radioisotope carbon-14 is 5730 years‚ how useful do you think this isotope would be for dating bones that are over a million years old? (2 marks) 3. Summarize the four major types of biochemical reactions studied in this lesson. For each type give its name‚ a word summary of what happens during the reaction‚ and an example of where the reaction might be biologically important

Organic compounds are very important to a body. They are help the body to do things and replenish it. The 4 organic compounds I will talk about are carbohydrates‚ lipids‚ proteins and nucleic acids. I will explain what they do and what they are made of. Carbohydrates are in foods‚ some examples are sugars and starch. The structure of a carb is ring shaped‚ it is an easy one to know. The monomer of a carb is monosaccharide‚ which means one sugar. A monosaccharide consists of glucose‚ fructose and

Title: Determining which organic molecules are present in a series of unknown dietary supplements ● Introduction: Our main objective was to find out if the dietary supplements that claimed to be providing high levels of proteins contained fillers such as starch and sugar. We developed and carried out tests to determine which organic molecules were present in a series of unknown supplements. This is important because it is important to know what is in the food you eat for yourself and not always reply

Are you weak‚ tired‚ and lazy all the time? With macromolecules‚ your body will be bigger‚ better‚ faster‚ stronger‚ and built to last longer! There are four major macromolecules that can give you more energy‚ strength‚ and enough fat to keep you warm and protected. In conclusion‚ the four major macromolecules are important to growth and development because they produce and store energy‚ create muscle to build a repair the body‚ create fat when it gets cold‚ and to tell when to release amino acid

Aim: To verify the buffering capacity of a phosphate solution using a pH meter and construct a titration curve of an amino acid to determine the pka values of its ionisable groups to identitfy an unknown amino acid. Method: The ratio of [HPO42-] to [H2PO4-] required to produce buffer solutions at pH values 5.9‚ 6.9 and 7.9 were calculated. 0.1M of H2PO4- and 0.1M HPO42- were used to mix appropriate volumes to 25mL of each of the buffer solutions. The calibrated pH meter was used to measure

Introduction to Biochemistry Biochemistry : a multidisciplinary science that explores the chemistry of living organisms and molecular basis for changes occurring in living cells. Principal areas of Biochemistry 1. Struture and Function of Biomolecules Based on structure depend the function (structure function relationship) Example: Hemoglobin S differs from regular adult hemoglobin (hemoglobin A) by just one single amino acid. A valine replaces a glutamine in the 6th position of the beta
