1 The nucleusss , which is essential for ss ss ss ss


function andsurvival of the cell.
ss ss ss ss ss



A) is the site of protein synthesis
ss ss ss ss ss



B) contains the genetic code ss ss ss



C) transforms cellular energy ss ss



D) initiates aerobic metabolism ss ss




2 Although energy is not made in mitochondria, they
ss ss ss ss ss ss ss


are knownas the power plants of the cell
ss ss ss ss ss ss ss ss


because they:
ss nn




A) contain RNAfor protein synthesis. ss s ss ss



B) utilize glycolysis for oxidative energy. ss ss nn ss



C) extract energy from organic compounds.

3 Although the basic structure of the cell plasma
ss ss ss nn ss ss ss


membrane isformed by a lipid bilayer, most of the
ss ss ss ss ss ss ss ss ss


specific membrane functions are carried out by:
ss ss ss nn ss ss ss



A) bound and transmembrane proteins. ss ss ss



B) complex, long carbohydrate chains. ss ss ss



C) surface antigens and hormone receptors.

that:
A) displace surface receptor proteins. ss ss ss



B) accumulate within cell gap junctions. ss ss ss ss



C) bind to contractile microfilaments.

metabolism,provides energy by:
ss ss ss



A) removing the phosphate bonds fromATP. ss ss ss ss s

is a correctly matched description and type of epithelial

10 Although all muscle tissue cells have some similarities,
ss ss ss ss ss ss ss


smooth muscle (also known as involuntary muscle)
