The concentration of 2‚3-BPG varies inversely with the pH‚ since it is inhibitory to catalytic action of bisphosphoglyceromutase. (5 marks) 5.

question. For these reasons‚ researchers have endeavored to engineer plants with genes that can bestow superior degradation abilities. A direct method for enhancing the efficacy of phytoremediation is to overexpress in plants the genes involved in metabolism‚ uptake‚ or transport of specific pollutants. Furthermore‚ the expression of suitable genes in root system enhances the rhizodegradation of highly recalcitrant compounds like PAHs‚ PCBs etc. Hence‚ the idea to amplify plant biodegradation of xenobiotics

than he or she uses‚ overweight and obesity result. 2. Not necessary 3. What is “metabolism”? What does human metabolism have to do with energy balance and body weight? Metabolism is the set of life-sustaining chemical transformations within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow and reproduce‚ maintain their structures‚ and respond to their environments. Metabolism is the process in which the body gets energy from food. It affects body weight because

We have four important macromolecules; carbohydrates‚ lipids‚ proteins‚ and nucleic acids. From these four‚ the macromolecule I chose for this assignment was carbohydrate. Carbohydrates branch off into three main categories; monosaccharides‚ disaccharides‚ and polysaccharides. I decided to focus on disaccharides‚ specifically sucrose. Sucrose is more commonly known as table sugar. It has a chemical formula of C12H22O11. It is physically described as a white‚ odorless (although when heated‚ it may

perfect way to burn pounds is to boost the metabolism so it loses calories more effectively. Fat Loss programs are planned to assist you to lose weight and fat by modifying your eating routines. The program swears to help you burn calories. There are no counting calories and no accurate exercise options to follow. The fat loss secrets are basically present in what and how you eat. The fat loss diet is necessary and would boost your energy and metabolism so your body can lose fats and minerals most

my efforts of exploring macro and micronutrients the goal will be to identify the types of both and the reasons why they are important for a normal functioning body. Macronutrients consist of the body’s energy supply‚ when we focus on a normal metabolism we would be describing the energy requirements that are necessary for the body’s cell function‚ tissue repair‚ and the muscle function in a human body. When we think about nutrients we need to remember that they are chemicals that any living organisms
