__________. 9. The name of a chemical reaction to break molecules by inserting a water molecule is called __________. 10. What are the 4 main elements of the body? 11. What are the 4 macromolecules called? What are their “building blocks”/subunits (monomers) called? Give functions of each macromolecule and examples. 12. What is the main energy currency of the body? 13. What is the smallest unit of life with living properties? 14. What is a cell called if it doesn’t have a nucleus

gas). This occurs because the molecules with the greatest energy (the “hottest” ones) tend to vaporize first. 2. List the four major classes or groups of biologically important macromolecules and explain one reason for the importance of each. The four major classes or groups of biologically important macromolecules are Carbohydrate, Lipids, Nucleic, and Protein. Carbohydrate are any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy

tested positive for lipids. The first group of foods that were tested was the fruits and they consisted of apples, bananas, plantains, and avocados. The apple, banana, and plantain contained starch and sugar and this is correct because these two macromolecules are present in plants. The only exception to this group is the avocado. It contains a small amount of starch (since it is still a plant), but it also contains proteins and lipids because of its single large pit (seed) whereas the other fruits

Testing for the macromolecules (Carbohydrates, Proteins and Lipids) Group Members Sonovia Culmer Welleana Ferguson Ashley Morley Jino Petit-Homme Anatomy & Physiology I: Biol 131/ section 01 Lecturer: Mr. Woodrow Smith Date: 11 February 2015 Introduction Carbohydrates, proteins and lipids are all organic macromolecules composed of polymers which are made up of smaller simpler subunits (monomers). These macromolecules have unique characteristics that allow them to

I. Answer 1. What do you know about proteins? Proteins are important molecules in cells, is one macromolecule organic. They are compound of large amino acid chains and distingue of the rest of the macromolecule by containing Nitrogen; they are involucre in the many processes of the organism, such as: the formation of membranes of the cells (structure), bioregulation (enzymes) and defense (antibodies). The structure three-dimensional and specific function of proteins this defined by the sequence

In this lab, we were trying to identify certain macromolecules commonly found in food and other substances. These macromolecules were carbohydrates(both simple and complex), proteins, and lipids. Carbohydrates are a simple, short-term source of energy, and they are used in making cell structures. Carbohydrates are made up of monomers(which are comprised of single molecules) called monosaccharides. Monosaccharides include glucose, sucrose, and galactose. Two monosaccharides can be combined by removing

Biology 119, Spring 2015 Review sheet for Exam 1 The exam is worth 100 points total. It will consist of approximately 47 multiple-choice questions worth 2 point each and 3-4 short essay questions. Bring a scantron and pencil to the exam. The best way to study is to review the posted lecture notes. I suggest printing of a blank copy and filling them in referring to your book and notes as little as possible. Continue this process until you can fill them in without assistance. Exam 1 will cover

Discuss the different processes of cellular exchange, with NAMED examples. Nucleus is at the centre of the cell, it has coded instruction that enables it to make specific protein; this is how ribosomes are made here. This is bounded by a double membrane; the cytoplasm is like material within the nucleus this is called the nucleplasm (Rowland, as biology, 2008). The nucleus stores, replicates and decodes DNA. , which gives each cell it unique characteristics; this means liver cells are is different

Chemistry of Life Matter is anything that occupies space. Matter is made of one or more elements. An element is the most pure form of matter. Elements are made of atoms. There are 111 elements and of these 92 are naturally occurring. Essential Elements About 25 elements are essential to life. These are called ‘essential elements’. 4 essential elements make up 96% of the human body. These are O, C, H and N. The other elements account for the remaining 4%. Trace Elements Certain elements
