BLD 204- EXAM 1 UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS
Question:
1. Describe the components of the cell memebrane
Answer:
Question:
2. State at least three functions of the cell membrane
Answer:
Structure, gatekeeper, barrier (certain things in certain things out)
Question:
3. Explain the function of the mitochondria
Answer:
Source of most ATP needed for energy
Question:
4. Explain the function of the lysosome
Answer:
Degrades materials. Contains enzymes that break things down.
Question:
5. Explain the function of the nucleus
Answer:
Contains genetic material (DNA) and is the control center of the cell
Question:
6. Explain the function of the Endoplasmic reticulum
Answer:
protein synthesis, modification and folding. Also stories Ca (sequestered here)
Question:
7. Explain the function of the Golgi complex
Answer:
modification, secretion and intracelluler transport of proteins and lipids
,Question:
8. Explain the function of the peroxisome
Answer:
Contains enzymes involved in metabolic reactions
Question:
9. Explain the function of the microtubules
Answer:
Move vesicles and provide structure to the cytoskeleton. Can be involved in
transport as well.
Question:
10. Explain the function of the microfilaments
Answer:
Made of actin and help to support cell movement
Question:
11. Explain the function of the ribosomes
Answer:
makes proteins
Question:
12. Define etiology and be able to use when discussing the
cause of disease and response of organism to disease
Answer:
Study of disease cause
Question:
13. Define pathogenesis and be able to use when discussing
the cause of disease and response of organism to
disease
Answer:
Development/ MECHANISM of disease
Question:
14. Describe ways normal cells or tissues can adapt to stress
and the signals that induce them: Hypertrophy
Answer:
increase cell/organ SIZE in response to stress
Increase workload in cells that CANT divide
, Question:
15. Describe ways normal cells or tissues can adapt to stress
and the signals that induce them: hyperplasia
Answer:
increase in NUMBER of cells; cells are CAPABLE of division
Question:
16. Describe ways normal cells or tissues can adapt to stress
and the signals that induce them: atrophy
Answer:
Cells SHRINK by loss of cell substance; may lose enough to effect whole organ;
not dead, but have DIMINISHED FUNCTION
Question:
17. Describe ways normal cells or tissues can adapt to stress
and the signals that induce them: metaplasia
Answer:
Reversible change; one cell REPLACE another. Improves function in light of stress,
increases risk
Question:
18. Describe ways normal cells or tissues can adapt to stress
and the signals that induce them: dysplasia
Answer:
ABNORMAL growth or development of tissue or organ
Cancer is an example
Question:
19. Describe ways normal cells or tissues can adapt to stress
and the signals that induce them: hypoplasia
Answer:
Below or INADEQUATE NUMBER of cells
Use not fully mature cells to take care of a problem, use less cells by slowing
down blood flow
Question:
20. Discuss homeostasis
Answer:
Keeping balance within the body. Good DNA, functioning PROTEINS, sound
MEMBRANE, enough nutrients and oxygen
