The endoplasmic reticulum is the term which describes an extensive network of tubes, sacs, and vesicles throughout a cell that provides transport as its main function. The endoplasmic reticulum is a small organelle and is found in most Eukaryotic cells. It is not found in red blood cells. The endoplasmic reticulum is a network in the core of the cell and occurs within the nuclear membrane and is involved in the synthesis of lipids and proteins. The endoplasmic reticulum also usually has ribosomes attached to it.
<span>The function of an ADP, or Adenosine diphosphate molecule, is to assist in the flow of energy throughout the cell. The basic structure of the molecule itself is made up of three main parts - a sugar backbone, which is attached one adenine molecule and two phosphate groups, which is then bonded to a 5' carbon atom of ribose. </span>
Hearing.
The process of hearing starts by pressure waves that are captured by our ears and taken inside the ear by the ear canal reaching firstly the ear drum. The ear drum then vibrates according to the pressure waves that were captured making the acicular (a set of 3 little bones) enter in motion. This vibrations then move from the acicular to the inner ear. Within the inner ear we can find the cochlea which is where this mechanical waves are converted into electrical signals and then passed to the brain. The auditory cortex of the brain then interprets this signals as sounds and gives them meaning.
