1 The nucleustf , which is essential for function tf tf tf tf tf




andsurvival of the cell.
tf tf tf tf




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




B) contains the genetic code tf tf tf




C) transforms cellular energy tf tf




D) initiates aerobic metabolism tf tf




2 Although energy is not made in mitochondria, they are
tf tf tf tf tf tf tf tf




knownas the power plants of the cell because they:
tf tf tf tf tf tf tf tf nn




A) contain RNAfor protein synthesis. tf ft tf tf




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




C) extract energy from organic compounds. tf tf tf tf




D) store calcium bonds for muscle contractions.

3 Although the basic structure of the cell plasma membrane
tf tf tf nn tf tf tf tf




isformed by a lipid bilayer, most of the specific membrane
tf tf tf tf tf tf tf tf tf t f




functions are carried out by:
tf nn tf tf tf




A) bound and transmembrane proteins. tf tf tf




B) complex, long carbohydrate chains. tf tf tf




C) surface antigens and hormone receptors. tf tf tf tf




D) a gating system of selective ion channels.

communicationutilizes chemical messenger systems
tf tf tf tf




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




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




C) bind to contractile microfilaments. tf tf tf




D) release secretions into extracellular fluid. tf tf tf tf

,5 Aerobic metabolism, also known as oxidative
tf tf tf tf tf




metabolism,provides energy by:
tf tf tf




A) removingthe phosphate bonds fromATP. ft tf tf tf ft




B) combining hydrogen and oxygen to formwater. tf tf tf tf tf




C) activating pyruvate stored in the cytoplasm. tf tf tf tf tf




D) breaking down glucose to form lactic acid. tf tf tf tf tf nn

9 Connective tissue contains fibroblasts that are responsible for:
tf tf tf tf tf tf tf




A) providing a fibrous framework for capillaries. tf tf tf tf tf




B) synthesis of collagen, elastin, and tf tf tf nn



reticularfibers.

smooth muscle (also known as involuntary muscle)
