Liberty University BIOL 101 Quiz 2 Complete Solution s Correct Answer s Key More than two versions In an organism, the structure of ___________ determines its function; in a cell the structure of ____________ determines its function. A common form of energy storage in the roots of plants: A condensation reaction joins two organic molecules together creating an H+ ion and an – OH ion. These then The tertiary structure of a protein describes its A fat molecule consists of: Testosterone signals all of the following in the human male except: Which of the following examples from the living world exhibit well - designed structures supporting well - designed functions? In a protein, the sequence of amino acids often folds initially into alpha helices and/or beta pleated sheets. These helices and sheets are two examples of Polymers are degraded by the cell into monomers in a process in which the __________ from a water molecule stabilize the broken _________ in the polymer molecule. The bases in a DNA molecule include all of the following except The structure of testosterone could best be described as Which of the following is the name for a class of sugar molecules? The four major classes of biomolecules are: An amino group, a carboxylic acid group, a hydrogen atom and one or more atoms composing a side chain (“R” group) all together make up a monomer called A phospholipid is made up of: A carbohydrate contains ________ atoms. Which of the following is not a lipid?

The carbon atom is uniquely suited to building large molecules because it: A large polymeric molecule that is nonpolar over most of its structure but very polar at one end: Each of the following is the name of a class of monomers used as building blocks in the polymers of living organisms except for The structure of a phospholipid molecule admirably suits it to the function of The Miller - Urey experiments used random jolts of electrical energy to produce a variety of amino acids and other molecules. One weakness of these experiments: Virtually all monomers in cells are built into polymers by removing _________ from one monomer and ____________ from the other monomer, and using these products to form ____________ Which of the following molecules is a polymer? Carbon atoms are uniquely suited for building molecules in living things because In living organisms well - designed structures support well - designed functions. This intricacy of design is seen at Hemoglobin Carbohydrates include all of the following except Which of the following is not a carbohydrate The carbon atom Glycoproteins DNA contains four kinds of nitrogenous bases whose principle function is Which is not a function of a lipid Cellulose and starch are both long polysaccharide chains made of glucose molecules. But a cell’s enzymes can tell them apart because When a single hemoglobin subunit picks up an oxygen molecule Amino acids are building blocks used in building proteins. About how many different kinds of amino acids are there for this purpose Which class of biomolecules is most efficient as a long - term storage, concentrated source of energy? What stimulates the release of the enzyme amylase into the pancreatic duct so that it can break down starches?

Which of the following terms describes or names a cell that swims like an animal using cilia, but is green in color like a plant? Which of the following is NOT part of the Cell Theory? A eukaryotic cell structure (organelle) that results when a vesicle formed from the Golgi complex simply remains in the cytoplasm of the cell: Which of the following statements is an element of cell theory? Biologists have discovered living things that defy (do not agree with) “Cell Theory”. Which aspect of the cell theory is most directly violated by slime molds? When the enzyme amylase from the pancreas is finally ready for use, it is stored within cell cytoplasmic vesicles called___. In order for the nasty bacterium Streptococcus pyogenes to adhere to your throat cells, attachment to your cells must be made. This is done using new proteins called _____ and new cell structures called ________. Two unusual features of protozoan cells like Paramecium are It is difficult for human macrophages to detect and destroy Strep cells because Strep cells A prokaryotic cell is protected against osmotic swelling and rupture by its A eukaryotic cell structure (organelle) in which the final stages of protein maturation are completed: Energy processing in eukaryotic cells often involves linearly arranged reactions. That is why energy processing organelles have highly folded membranes within them — structures known as Respiratory proteins, ion channels, transport proteins and attachment point proteins are all examples of protein found ____ are little molecular machines (eukaryotic cell structures) that move vesicles and organelles throughout the cytoplasm of the cell. When a protein molecule has folded into its final form, it leaves the endoplasmic reticulum (RER) and travels to the Golgi complex by means of Some species of Paramecium receive sugars from

Within an acinar cell, the enzyme amylase reaches its final form within An important function of the eukaryotic cell membrane is to Which of the following is NOT a kind of protein found in a prokaryotic membrane? It is impossible to write a brief dictionary definition of life because ____________ house enzymes that trap carbon dioxide and bind it to larger substrate molecules. What structures inside the eukaryotic cell provide a skeletal framework that supports and shapes the cell? ________ and ________ are structures that walk along microtubules in the eukaryotic cell carrying vesicles from place to place. To say that “the cell is the unit of life” means that Which of the following organisms is considered to be eukaryotic ____ are little molecular machines that move vesicles and organelles throughout the cytoplasm of the cell Cells are small because Which of the following occurs in the nucleolus In order for nasty bacterium Streptococcus pyogenes to stick to your throat cells, attachment proteins must be made. These proteins are called Prokaryotic organisms have a definite lack of which of the following A sal tine cracker is mostly starch. If cracker bits are digested into small subunit parts, what kind of molecule would be the product? Discrete, visible lengths of DNA sequence found in human cell nuclei are known as Ignoring cell size and just counting numbers, most of the cells in nature are this type Bacteria are typically very mall, yet even the largest bacterium is still a prokaryote because it
