1. What is metabolic absorption?: cells taking in and using nutrients and other substances from their
surroundings
2. What organs cells are specialized to carry out absorption?: inestine and kidney
3. How to cells become specialized?: through process of differentiation or maturation to eventually
preform one of the 8 chief cellular functions
4. What are the 8 chief cellular functions?: movement, conductivity, metabolic absorption, secretion,
excretion, respiration, reproduction, and communication
5. During cell injury, what is released that is capable of cellular auto digestion?-
: lysosomal enzymes or hydrolase
6. What are hydrolases?: digestive enzymes in lysosome that function as the intracellular digestive system
and are capable of digesting most cellular conssiosuents completely to their basic components
7. What are lysosomal storage diseases?: pompe disease, tay-sacks, and gout
8. What is crucial for normal digestion of cellular nutrients, intercellular debris,
and potentially harmful extracellular substances that must be removed from
the body?: lysosomes
9. As cells complete their life span and die what happens?: lysosomes digest the resultant
cellular debris in a process called auto digestion
10. What is responsible for cell divison and controlling genetic information?: the
nucleus
11. What is a small dense structure composed largely of RNA, most of the cellular
DNA, and the DNA-binding proteins that regulate its activity?: nucleolus
12. What are the primary functions of the nucleus?: cell division, control of genetic info, as well
as the repication and repair of DNA and the transcription of the information stored in DNA
13. Cell membranes contain which major chemical components?: lipids and proteins
14. What are not uniformly distributed but can separate into discrete units called
microdomains?: lipids and proteins
15. Lipids and proteins act as the "_________" for the structural integrity of the
membrane.: molecular glue
16. What does it mean for a lipid to be polar or amphipathic?: part hydrophobic (water
hating) and part hydrophilic (water loving)
