In this type of passive transport process a solute, such as glucose, binds to a specific transporter protein on one side of the membrane and is released on the other side after the transporter protein undergoes a change in shape?
This type of membrane protein serves as sort of an anchor, and may connect the plasma membranes of two neighboring cells together.
swell and burst
A red blood cell placed in distilled (pure) water (which is hypotonic) would do this.
One type of human cell (spermatozoan) is capable of movement because its has this type of microtubule.
What is an accurate statement regarding the fluid-mosaic model of cell membrane structure?
Phospholipids form a bilayer that is largely impermeable to water soluble molecules.
This is a transport process by which cells secrete vesicular materials into the extracellular fluid
The characteristic of plasma membranes allowing only some substances to move through is known as
What statement best describes lipid molecules?
In general, they have few polar covalent bonds, and are therefore hydrophobic and insoluble in water.
Secondary Active Transport
In this transport process, the energy stored in the Na+ or H+ concentration gradient is used to drive other substances across the membrane against their own concentration gradients.
True or False: Most enzymes are non-specific, meaning they may bind to substrates indiscriminately and catalyze a wide range of reactions in the body.
This directional term means farther from the attachment of a limb to the trunk or farther from the origination of a structure.
A false statement regarding cytoplasmic organelles would be:
The golgi complex is the site of protein transcription.
During _______ the chromosomal centromeres split and the chromosomes migrate to the opposite ends of the cell.
