Under which conditions do most types of cells function at optimal levels

Biology
1 answer:
Scrat [10]3 years ago
6 0

Explanation:

Cells maintain a constant internal environment; this process called homeostasis, ensures that cells obtain an optimal environment in which they can best function.

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.

It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

For example, cells within the human body function at an optimal temperature between 97°F (36.1°C)  and 99°F (37.2°C). This is due to the optimal temperature requirement of the enzymes within the human body, which requires this specific range to obtain activation energy.

2. Sympathetic - functions as the flight and fight response.

3. Autonomic - it functions as the controller of automatic response.

4. Somatic- functions as controling voluntary response.

5. Peripheral- works as motor nerves and sensory which runs from and to central nervous system.

34kurt

Answer

Complex barrier to the flow of substances out of the cells,and restrictions to inflow of unwanted substances into the cells. The hydrophobic and hydrophilic nature of the cell membrane controls the entry of substances from the extracellular medium into the intracellualr. In addition the polarity restricts certain substance movement across the walls.

Serve as the selective channels  for the  influx of certain substances into the cells, and the out flux of wastes.This is through ion channels for the movements of ions across.

Provide insulation to the cells,to maintain the constant internal temperature,this is through the presence of lipids as( Phospholipids and cholesterol).The latter prevent the clogging of the lipids in the cell membrane therefore preventing frozen up of the cell membrane,providing insulation.

Separation of metabolic process in the cell.

Explanation:

Cell membrane-This is present in all cells.But the variation of its constituents makes it unique to each cell. Although it performs the same role, the location and role the cells it bounded, reflects its  constituents, it is made up of lipids, carbohydrate, protein and cholesterol
