BIOCHEMICAL PROPERTIES OF LIPIDS STUDY GUIDE WITH
COMPLETE SOLUTION!!
Phospholipid Bilayer
Answers :Arrangement with hydrophobic tails inward and hydrophilic heads
outward.
Selective Permeability


Answers :Property of the bilayer allowing specific molecules to pass through.
Saturated Fatty Acids


Answers :Fatty acids with no double bonds, decreasing membrane fluidity.
Unsaturated Fatty Acids


Answers :Fatty acids with one or more double bonds, increasing membrane
fluidity.
Cholesterol


Answers :Regulates membrane fluidity; stabilizes at high temps, prevents stiffness
at low temps.
Facilitated Diffusion


Answers :Movement of molecules with the help of transport proteins.
Osmosis


Answers :Passive movement of water across a selectively permeable membrane.
Active Transport

, Answers :Requires energy to move substances against their concentration gradient.
Electrochemical Gradient


Answers :Combined influence of solute concentration and electrical gradient
across a membrane.
Signal Transduction


Answers :Process of cells responding to external signals by changing behavior.
Membrane-bound Receptors


Answers :Receptors binding polar signals on the cell membrane.
Cytoplasmic Receptors


Answers :Receptors binding nonpolar signals within the cell.
Phosphorylation Cascades


Answers :Series of enzyme activations amplifying a signal in cell signaling.
Cellular Respiration


Answers :Process of producing ATP from glucose in cells.
Glycolysis


Answers :Metabolic pathway yielding ATP and pyruvate in the cytoplasm.
Citric Acid Cycle
