How do specialized cells perform their functions in an organism?

Answer 1

Specialized cells include red blood cells, nerve cells, etc... These are cells that make up eukaryote organisms that perform the task they are designed to do better than a plain-old generic cell. Because of this, they can only survive in conjunction with the rest of the organism; their specialization prevents them from doing other tasks that are important for life but are instead performed by the organism's other specialized cells. Specialized cells may have more of a certain organelle than other cells (Your pancreas cells have a larger Golgi Body system because they are designed to export chemicals to the rest of your body), and some may be missing what are considered to be essential organelles (red blood cells are little more than a lot of hemoglobin in a phospholipid membrane). if a body part that in your body.

Primary Functions of Calcium in Cell Culture Systems:

Calcium is involved with a wide range of vital cell functions including enzyme activities, attachment, motility, tissue morphology, metabolic processes, signal-transduction, replication, and electrochemical responses by specialized cells such as muscle and neural cells. It is stored primarily in the endoplasmic reticulum (ER). Proteins that bind calcium within the ER lumen include protein disulphide isomers, calreticulin, endoplasmic and reticulocalbin. Cells contain a number of none lumen calcium-binding proteins that mediate cellular activities and signaling cascades. Examples of these proteins include the Clementine's, troponin C, climatology and S-100 proteins.

Calcium Cell Signaling: Calcium is involved at several levels in receptor mediated signal transduction. It facilitates the binding of protein kinase C to cell membranes, and upon its release from the ER by inositol 1,4,5 trisphosphate it binds and activates calmodulin. The cyclic nucleotides, cAMP and cGMP, function as second messengers. Activated calmodulin regulates cyclase and phosphatase enzymes that control the intracellular pools of these nucleotides. Activated calmodulin also regulates protein kinases and phosphatases involved in cell cycle progression

Cell Attachment and Tissue Morphology: Calcium facilitates the attachment of cells to substrates and to one another and mediates many cellular events that affect cell movement, shape and three-dimensional structure. It modulates the function of cadherins, selectins and integrins. These families of adhesion molecules regulate homologous cell-cell, heterologous cell-cell and cell-matrix interactions, respectively. Calcium is also involved in signaling attachment events from inside the ER lumen.
