LAB 9 THE ENDOCRINE SYSTEM BIO201L
STRAIGHTERLINE SCORED PRACTICE TEST
BANK 2026 TESTED QUESTIONS WITH
ANSWERS GRADED A+
⩥ What are the regions and cavities in the human body? Answer:
Abdominal (digestive organs), thoracic (heart, lungs), cranial (brain),
spinal (spinal cord), pelvic (bladder, reproductive organs, rectum).
⩥ What are the directional terms and sectional planes? Answer:
Directional: anterior/posterior, superior/inferior, medial/lateral,
proximal/distal, superficial/deep. Planes: sagittal, midsagittal,
coronal/frontal, transverse/horizontal.
⩥ What are the components of a cell? Answer: Cytoplasm (cell interior),
intracellular fluid, extracellular fluid, cytosol (fluid in cytoplasm),
neoplasm (abnormal growth).
⩥ What are the structures and functions of organelles? Answer:
Mitochondrion (ATP production), Rough ER (protein synthesis), Smooth
ER (lipid synthesis), Golgi (protein modification/packaging), Nucleolus
(rRNA/ribosome assembly), Ribosomes (protein synthesis).
, ⩥ What is the difference between hydrophobic and hydrolytic? Answer:
Hydrophobic: repels water (lipids). Hydrolytic: breaks bonds using
water (enzymes, catabolism).
⩥ What are the molecules and functions of the plasma membrane?
Answer: Phospholipids (barrier), cholesterol (stability), proteins
(transport/signaling), carbohydrates (cell recognition).
⩥ What is the relation of pH to solution concentration? Answer: pH =
−log[H⁺]; low pH = acidic, high H⁺; high pH = basic, low H⁺.
⩥ What is the composition and function of proteoglycans and
glycoproteins? Answer: Proteoglycans = protein + GAGs; structural
support in ECM. Glycoproteins = protein + sugar; cell signaling,
recognition.
⩥ What is the structure and function of proteins? Answer: Composed of
amino acids; levels: primary → quaternary. Functions: enzymes,
transport, signaling, structural support.
⩥ How are organs classified in specific body cavities? Answer: Lungs
(thoracic), heart (thoracic), brain (cranial), liver (abdominal), bladder
(pelvic).
