BMS 595 Human Physiology Exam I –
Terminology correctly answered to pass
Passive Transport - correct answer ✔✔No energy requirement; diffusion, facilitated diffusion,
filtration, and osmosis
Active Transport - correct answer ✔✔Against concentration gradient and needs carrier.
Bulk transport- Exocytosis, endocytosis, phagocytosis, and pinocytosis
Simple diffusion - correct answer ✔✔always happens in favor of [] gradient based on kinetic
energy of molecules causing their movement through membrane openings or intermolecular
spaces.
Flicks Law of Diffusion - correct answer ✔✔net rate of diffusion C.A.AS.T/R
c- diffusion coefficient
A= cross sectional area
AS= concentration gradient
T =temperature
R = molecular radius
Facilitated Diffusion - correct answer ✔✔In favor of concentration gradient carrier. There is a
max limit depending on the carriers and their ability to undergo conformational changes.
Osmosis - correct answer ✔✔Movement of solvent
, Filtration - correct answer ✔✔Movement of solvent and solute due to hydrostatic pressure
gradient
Active Transport - correct answer ✔✔Carrier typically a lipoprotein that binds to the substance
transport to other sides. Then, the enzymes breaks the complex, and lipid insoluble substance
cannot go back following concentration gradient. The carrier goes back to pick another
substance. It is limited transport and against the concentration gradient. Na/K pump.
Bulk Transport; Endocytosis - correct answer ✔✔Phagocytosis for solids
Pinocytosis - correct answer ✔✔for liquid
Exocytosis - correct answer ✔✔to secret ore excrete substance from the cell.
Osmotic Pressure - correct answer ✔✔For a given solution, the exact amount of pressure
required to stop osmosis. It depends on the numbers of particles.- one osmole is one gram for
MW of undissociated solute; glucose.1 osmole = 1g MW = 180g of glucose.
One mole of a substance is_____ - correct answer ✔✔equal to its MW in grams.
osmoles____ - correct answer ✔✔always the same number of solute particles
What is the Osmolality? - correct answer ✔✔a solution that has 1 oslmole of solute dissolved in
each kg of water- 1 osmolality of 1 osmole /kg
What is the normal osmolality of ECF an ICF? - correct answer ✔✔300 milliosmoles/kg or
300,000 osmole/liter
