QUESTION SET APPROVED
◉ Ionic Bonds. Answer: Bonds formed between ions with opposite
charges. (Gaining or loosing electrons in order for a bond to form)
◉ ionic bonds are. Answer: Electrolytes: necessary for nerve
impulse, conduction, muscle contractions and water balance.
◉ Covalent Bond. Answer: Bonds formed when atoms share
electrons.
◉ Covalent Bonds are used for. Answer: Holding together chemical
building blocks that make up a strand of DNA
◉ Hydrogen Bonds. Answer: An extra-strength dipole-dipole
attractive force due to a large electronegativity difference between
hydrogen and nitrogen, oxygen, or fluorine.
◉ Hydrogen bonds are used for. Answer: Holding the DNA helix
together and allowing the DNA to be stable, as well as be opened for
copying.
,◉ Monomer. Answer: A simple compound whose molecules can join
together to form polymers
◉ Polymer. Answer: molecules composed of many monomers;
makes up macromolecules
◉ Examples of macromolecules. Answer: carbohydrates, lipids,
proteins, nucleic acids
◉ dehydration synthesis. Answer: A chemical reaction in which two
molecules covalently bond to each other with the removal of a water
molecule.
◉ Hydrolysis. Answer: the chemical breakdown of a compound due
to reaction with water.
◉ Amino acids. Answer: monomers that make up proteins
◉ Polypeptide. Answer: long chain of amino acids that makes
proteins
◉ The role of a protein. Answer: make up the structures of the body
as well as regulate the body's tissues and organs.
, ◉ what makes up an amino acid. Answer: A central carbon, an amino
group (NH2), a carboxyl group (COOH), and a hydrogen atom.
◉ structure of a carbohydrate. Answer: carbon, hydrogen, oxygen
◉ sweet. Answer: Meaning of "saccharide" in greek
◉ polysaccharide. Answer: Glycogen is a
◉ Lipids. Answer: molecules that aren't soluble in water
◉ The role of a lipid. Answer: Energy storage, signaling in hormones,
make up membranes
◉ structure of lipids. Answer: They are long fatty acids attached
together to make long chains. Made of Carbon and hydrogen
◉ DNA. Answer: stores genetic information
◉ RNA. Answer: translates DNA instruction and facilitates protein
synthesis
