Organic Molecules * Large organic molecules are called macromolecules * Four major categories of macromolecules: 1. Proteins 2. Nucleic Acids 3. Carbohydrates 4. Lipids * Several of these are long chains of smaller subunits. * The smaller subunits are known as monomers * The long chains of monomers are known as polymers * Four groups of Macromolecules * Building Macromolecules – Monomers and Polymers * Molecules, such as amino acids

activities that can lead to the formation of a new cell wall. Choice E – Mitochondrial cristae is incorrect. The mitochondria are found in nearly all cells and is responsible for cellular respiration, the process in which ATP is formed from simple macromolecules. The organelle is bounded by a double membrane, the inner membrane being the mitochondrial cristae. The purpose of the cristae is to increase the surface within the mitochondria allowing electrons to pass through using the electron transport chain

human body, where the metabolic processes happen to in order to maintain life. It itself is considered a mini-organism made up from organs called organelles. These organelles are the structural and functional units and are created from several macromolecules connected together. A typical animal cell contains the following organelles (Tracey Greenwood, 2012): the nucleus (which houses the DNA), mitochondria (which produce energy), ribosomes (which make protein), the endoplasmic reticulum (for transportation)

Introduction : We had learned about that all living organisms are made up of molecules, each molecule serve its own special purpose. Molecule can be divided into two types, macromolecules and micro molecules. The molecules that we are studying in this experiment are macromolecules. In this case, we are studying on 3 types of macromolecules, carbohydrates, protein and lipid that present in different food. Carbohydrate can be divided into monosaccharide, disaccharide and polysaccharide. Monosaccharide is

practice exercises, students should be able to: • Define the biologically relevant interactions (bonds) between molecules • List functional groups commonly found in biological molecules. • List the different kinds of biological macromolecules and their monomers. • Summarize how polymers are made and broken down and how water participates in these reactions. • Describe the structure and functions of: o Simple sugars. o Nucleotides o Amino acids • Summarize

proteins, lipids, and nucleic acids. Each of these macromolecules (polymers) are made of smaller subunits (monomers). The bonds between these subunits are formed by dehydration synthesis. This process requires energy; a molecule of water is removed (dehydration) and a covalent bond is formed between the subunits (Fig.1). Breaking this bond is called hydrolysis; it requires the addition of a water molecule and releases energy. Each class of these macromolecules has different structures and properties. For

Chapter 1: • Name four properties that all life forms have. Order, Regulation, Growth and Development, and Energy Processing 2. Briefly discuss Darwin’s theory of Natural Selection. The process of descent with modification is Darwin’s take on evolution. The mechanism he proposed for this was called natural selection, which is another way of saying unequalled reproductive success. First, he observed overproduction and competition. Next, he observed individual variation. Finally Darwin concluded

Evolution is real because it's been proven so. It's been proven from samples of DNA , the discovery of fossils, matching traits from common ancestors , watching evolution happen over time, and identifying vestigial traits. Vestigial traits are traits that other species have also. For an example we have ears and so do monkeys. Although we are two different species and do a lot of stuff differently our ears function the same. Stuff like that makes you think ¨Did we both descend from the same ancestor
