BMSC207- Module 2 Test with Questionsand 100% Correct Answers
what do glycoproteins do? - Answer - forms protective coat (glycocalyx)
- cell-cell recognition/interaction
what does glycolipid do? - Answer cell to cell recognition/interactions
what is the role of phosolipids? - Answer bulk of the lipid component of cell membrane
what is the role of sphingolipids? - Answer lipid anchored proteins commonly attach
to them
What is the role of cholesterol? - Answer positioned between phospholipid heads to add
flexibility and help to make membrane impermeable to small water-soluble molecules
What is the role of in peripheral proteins? - Answer attached to integral
proteins participate in cell signaling and attachment of cytoskeleton
what is adipose tissue made up from? - Answer - 90% lipids, majority TG's
- small fraction water
,what is skeletal muscle made up from? - Answer - 75% water
- 18% protein
True or False. Water can freely move throughout body and will follow solutes. - Answer
True
Is the extracellular and intracellular compartments in osmotic equilibrium? - Answer yes
what is osmosis? - Answer the movement of water across a membrane in response to
solute concentration gradient
what way does water move? - Answer from a region of low solute concentration to a
region of high solute concentration and can move freely between the intracellular
and extracellular spaces
True or False. osmotic equilibrium equals chemical and electrical equilibrium. -
Answer False. Osmotic equilibrium does not equal chemical or electrical equilibrium
what does osmolarity describe? - Answer the number of particles in solution
how can osmotic movement of water be predicted? - Answer by knowing the solute
particle concentrations of each solution
what is isosmotic? - Answer solutions have identical osmolarities (equal)
what is hyperosmotic? - Answer describes the solution with the higher
osmolarity (greater than)
, True or False. Membranes separate one compartment from another - Answer True
Does the cell membrane consist of a single or double layer and what is it made of?
- Answer - double layer (bilayer)
- made of phospholipids with protein molecules inserted in them
What are the functions of a cell membrane? - Answer - physical isolation
- regulation of exchange with the environment
- communication between the cell and its environment
- Structural support
What is physical isolation, in relation to the functions of a cell membrane? - Answer -
physical barrier separating ICF and ECF
- separates cell from environment
What is regulation of exchange with the environment, in relation to the functions of
a cell membrane? - Answer - controls entry, elimination and release
What is communication between the cell and its environment, in relation to function
of a cell membrane? - Answer - contain proteins that allow for responding or
interacting with external environment
What is the structural support, in relation to the function of a cell membrane? - Answer
- proteins in the membrane are used to make cell-to-cell connections (tissue) and
to anchor the cytoskeleton
