Ionic bond
Give this one a try later!
A complete transfer of electrons between two atoms results in separate
positively charged and negatively charged ions.
Results of bone remodeling
Give this one a try later!
- Woven bone remodeled into lamellar bone
- Bone thickness increases
- Bone shape changes
- Bone adjusts to stress, repair, altered calcium
,Lipids Function and Composition
Give this one a try later!
Function: Protection, Insulation, Regulation, Vitamins, Structure, Energy
Composition: carbon, hydrogen, and oxygen
ATP powered pump
Give this one a try later!
ATP-powered pumps move specific ions or molecules across the
membrane using ATP to provide energy. Move specific ions or molecules
across the membrane; require ATP molecules to function
Plasma membrane function
Give this one a try later!
Separation, regulation, communication, and structure
(Outside of the membrane is positive, and the inside of the membrane is
negative)
Channel Proteins
Give this one a try later!
, One or more integral membrane proteins arranged so that they form a tiny
channel through the plasma membrane
Cross-bridge movement
Give this one a try later!
A cycle of events resulting in contraction proceeds very rapidly
Differences between smooth muscles and skeletal muscles
Give this one a try later!
smooth muscle has a slower contraction speed than skeletal muscle. This
difference is due to several factors. In smooth muscle, some of the Ca2+
required to initiate contractions enters the cell from the extracellular fluid
and from the sarcoplasmic reticulum. Therefore, it is the greater distance
that Ca2+ must diffuse, the slower rate at which action potentials are
propagated between smooth muscle cells, and the slower rate of cross-
bridge formation between actin and myosin myofilaments that are all
responsible for the slower contraction of smooth muscle.
Action Potential Propagation
Give this one a try later!
• "Propagate" - to spread from one location to another
• AP does not move along the membrane: new AP is generated at each
successive location
• "All-or-none" principle: AP are all identical
, • Frequency: number of APs produced per unit of time; stronger stimulus =
higher frequency

Monosaccaride
The Synapse
Give this one a try later!
• Junction between a neuron and another cell
• Site where action potentials in one cell cause action potentials in another
cell
• Types of cells in synapse - Presynaptic
- Postsynaptic
Basic functional unit of the muscle
