Chapter 1 Smart Book Review Questions The type of lipid that is important for storage is Triglyceride Due to their charged, hydrophilic heads and hydrophobic, nonpolar tails, Phospholipids can assemble into layers like those found in membranes. Which of the following are ringed compounds that are commonly found in the cell membranes of animals and fungi? Steroids Staphylococcus aureus and Staphylococcus epidermidis are bacteria that share the same Genus For the organism Staphylococcus aureus, aureus represents the Species level of classification. The outer covering of gram-negative bacteria contains lipopolysaccharide, a complex of carbohydrate and lipid responsible for symptoms such as fever and shock. In aqueous solutions, the charged heads of phospholipids are attracted to the water phase, and the nonpolar tails are repelled. This property causes lipids to naturally assume single and double layers Among eukaryotes, there are single and multicellular organisms Most Macromolecules are made up of monomers linked into polymers The most common and universally important hexose is Glucose Beyond the primary structure of the order of amino acids in a protein chain, there are up to three levels of folding and association that lead to significant complexity and functional specificity. There are a total of four levels 1. 2. 3. 4.

Primary Secondary Tertiary Quaternary

When exposed to an aqueous solution, phospholipids can form single and double layers because their charged heads are attracted to the water phase and their Nonpolar tails are repelled from the water phase.

The scheme that represents the relationship between groups of living organisms due to their relatedness by descent is called phylogeny A class of ring-shaped compounds that are commonly identified as animal hormones and cell membrane components in animals and fungi is the Steroids or sterol Staphylococcus aureus and Staphylococcus epidermidis are bacteria that share the same genus For the organism Escherichia coli, coli represents its Species name. Some proteins can assume a level of quaternary structure in which two or more polypeptides assemble to form a larger, multiunit protein.

What is biotechnology The use of microbes or their products for commercial or industrial purposes

An environment or material that is completely free of all life forms (including spores) and virus particles is referred to as sterile A network of polysaccharide chains cross-linked by short peptides that forms the structural support of bacterial cell walls is called peptidoglycan Lipids encompass which four of the following groups of compounds    

Phospholipids Triglycerides Waxes Steroids

Triglycerides are composed of glycerol and fatty acids In living systems, the predominant organic molecules are proteins, which are largely responsible for the structure, behavior, and unique qualities of a cell. Designing organisms in the industrial setting that can provide human products through genetic engineering or clean up environmental waste through bioremediation is part of the subdiscipline of microbiology referred to as biotechnology The primary concerns of modern taxonomy are naming, classification and identification

three major taxonomic groups, Bacteria, Archaea, and Eukarya, which are called Domains The outer covering of gram-negative bacteria contains lipopolysaccharide a complex of carbohydrate and lipid responsible for symptoms such as fever and shock. Cells that contain a nucleus and a number of other membrane-bound organelles are called eukaryotic, cells. All organisms are constructed from a few major types of biological molecules called macromolecule; large molecules made of repeating subunits called monomers. A monosaccharide is the simple sugar building block for carbohydrates consisting of 3 to 7 carbon atoms. A compound in which polysaccharides are linked to peptide fragments that provides the main source of structural support to the bacterial cell wall is peptidoglycan Proteins are polymers composed of amino acids The simplest and smallest unit of a carbohydrate is specifically called a monosaccharide A compound in which polysaccharides are linked to peptide fragments that provides the main source of structural support to the bacterial cell wall is peptidoglycan All organisms are constructed from a few major types of biological molecules called macromolecules; large molecules made of repeating subunits called monomers. Chains of amino acids comprise Proteins Due to their charged, hydrophilic heads and hydrophobic, nonpolar tails, Phospholipids can assemble into layers like those found in membranes. A network of polysaccharide chains cross-linked by short peptides that forms the structural support of bacterial cell walls is called peptidoglycan The simplest and smallest unit of a carbohydrate is specifically called a monosaccharide Large compounds that are composed of many smaller molecular subunits, most notably biochemicals are referred to as macromolecules Which of the following describes a lipopolysaccharide?  
