Chapter 5 Quiz

 
Chapter 5 Biology Quiz, open book, Reece/ Campbell
     There are four classes of life’s organic compounds:  c_______________, p______________, n_________ a__________, and lipids.  The first three are formed from p____________s.  The building blocks of p___________ are monomers.
     Monoers are connected by a reaction in which two molecules are covalently bonded to each other through loss of a w______molecule, in a process called a condensation or dehydration reaction.  They come apart again in the opposite reaction, called h________, where a water is added.
     In the body, p_________ are broken up into their m___________ (often in the digestive tract), the m______ are released and absorbed into the bloodstream for distribution to all body cells.  The cells can then reassemble the m__________s into p________s.
     Carbohydrates are built from s________ and their p__________s.  The simplest carbohydrates are m___________, known as s_________ sugars.  They generally have molecular formulas that are some multiple of _____________. 
     In aqueous solutions most sugars form r________.
     Monosaccharides are major n___________ for c_________.
     A disaccharide consists of two monosaccharides joined by a glycosidic linkage.  The most pevalent disaccharide is sucrose, which is t________ s______.  Sucrose’s two monomers are g______ and f_______.  L___________ is the sugar present in milk.
     S__________ is the storage polysaccharide of plants.  Animals store a polysaccharide called g______, a polymer of glucose that is stored in the liver and m__________ cells.
     The polysaccharide that is a major component of plant cell walls is c___________.
      The polysaccharide that is part of arthropods’ exoskeletons is c________.
     L___________ are a class of large biological molecules that do not contain p_______ and are hydro____________.  F__________s store large amounts of energy.  S_____________ fats are solid at room temperature, u____________ fats are generally liquid at room temperature.  Hydrogenated oils have had a ______________ atom inserted to make them __________ at room temperature.
