Describe characteristics and importance of the four major macromolecules – review the structure of each macromolecule (what they are comprised of) as well as examples: Carbohydrates-Compounds containing principally carbon‚ hydrogen‚ and oxygen atoms in a ratio of 1:2:1. Are a group of organic compounds in foods and living tissues and consist of sugars‚ starch‚ and cellulose. They can be broken down to release energy in the body Proteins-Macromolecule containing one or more polypeptide chains. are nitrogenous

acids. These organic molecules are used to produce ATP (Adenosine triphosphate). We break down these macromolecules (large biological molecule) by a process called digestion (when enzymes break down large molecules into smaller ones). This is also a catabolic reaction (a metabolic reaction that results in the breakdown of complex molecules) Humans use different process to break down these macromolecules. Carbohydrates (contain carbon‚ hydrogen‚ and oxygen and can be broken) are broken down through cellular

least about. As OpenStax CNX puts it‚ “Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules”. Proteins are “Macromolecules that contain nitrogen as well as carbon‚ hydrogen‚ and oxygen”(Miller‚ Kenneth R.‚ and Joseph S. Levine 48). Macromolecules are exceedingly large molecules that can be made up of several lesser molecules called proteins. These proteins are made up of numerous amino acids‚ which are “Compounds

Which of the following statements concerning cellular metabolism is FALSE? Answer Energy obtained from nutrients or light is stored in the bonds of ATP. ATP is used in the formation of macromolecules. Enzymes are used in both catabolic and anabolic reactions. Macromolecules are converted into cell structures via catabolism. The goal of metabolism is reproduction of the organism. 2 points Question 6 1. Enzymes known as lyases participate in __________ reactions
