Smooth muscles are spindle shaped, non-striated muscles and have uninucleated fibers. They are involuntary muscles and are found in the walls of internal organs such as the organs of digestive system. Peristalsis of smooth muscles of digestive system creates a wave like pattern of muscle contraction and moves the food through the system. Images A and B represent skeletal and cardiac muscles respectively both of which have striated fibers.
Smooth muscle is found in the walls of hollow organs throughout the body.
Smooth muscle contractions are involuntary movements triggered by impulses that travel through the autonomic nervous system to the smooth muscle tissue.
<u>The smooth muscle of the alimentary canal or the digestive tract facilitates the peristaltic waves that move swallowed food and nutrients.</u>
During translation peptide bonds are formed from the (N) to the (C) terminus by removal of water also referred to as dehydration or condensation and catalyzed by RNA referred to as a ribozyme that forms part of the ribosome.
In the process of photosynthesis, plants that contain chlorophyll utilize carbon dioxide and water using energy from sunlight that is absorbed by chlorophyll to make glucose + oxygen.
Biochemical tests and use of media allow physicians to identify
the type of bacteria causing a disease (such
as whether its gram+ or gram-) and use appropriate
antibiotic effective against the bacteria. Another clinical significance is to
determine the resistance of bacteria to antibiotics (this is conducted using susceptibility tests).
