BIOLOGY 235
MIDTERM 1- VERSION B
Know components of the lipid bi-layer
o Phospholipids, Cholesterol, and Glycolipids
Bonds between water molecules- what type of bond is it?
o Hydrogen Bond
Facilitated diffusion and what role does carrier protein play
o Channel mediated or Carrier mediated. Moves solute down conc. Undergoes
shape change
Know Transcytosis
o Endocytosis to enter, Exocytosis to exit
Is synovial membrane considered an epithelial membrane?
o No, doesn’t have epithelium. Lines joints and connective tissue.
Know what role triglycerides and cholesterol plays in body
o Triglycerides: Energy storage (twice efficient)
o Cholesterol: synthesize steroids. Makes bilayer stronger, less fluid. Except at low
temperature
Know location of the Nail Bed (hyponchium)
o Underneath Nail Body
o Hyponchium secures nail to fingertip
o Eponychium (cuticle) is stratum corneum above and proximal to lunula
Which layer of the epithelium is not present in Thick skin?
o Thin Skin doesn’t have lucidum. Thick skin has Basale, Spinosum, Granulosum,
Lucidum, Corneum BSGLC
Properties of Enzymes
o Lowering activation energy to speed up biochemical reactions
What is not a common characteristic of epithelium?
o All epithelium is tightly packed in sheets by cell junctions and without BV except
ones lined on BV. Function as barrier, secretion, protection. Types –
covering/lining and glandular
Choose example of a positive feedback system
o Birth, Blood loss
Wound healing- does it result in Fibrosis?
o Near perfect if parenchymal cells. If stroma fibroblasts repair, collagen and ECM
causes scar.
What lines the Medullary Cavity?
