Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion.

Homeostasis

Using the South University Online Library or the Internet, research about homeostasis.

Based on your research and understanding, provide your response to the following tasks:

*Analyze the feedback mechanisms that maintain homeostasis, and what happens when these systems do not function appropriately.

*Provide two specific examples for each.

*Provide the organizational levels in order, beginning at the atom.

*Then, analyze how each level relates to specific functions and to each other.

*Evaluate metabolism, anabolism, and catabolism.

*Then, distinguish them by providing an example for each of these and the end result for that reaction.

*Analyze and define internal and external respiration in terms of physiology and anatomy.

Please answer all questions....

Solution

Answer :-Homoestasis is the ability of an organism to maintain internal stability or in equilibrium whenever there is variation or change in the environmental factors. For example in humans higher glucose level in the blood triggers the release of hormone insulin from pancreas that lowers blood sugar level in the blood and when blood sugar level drips too low another hormone glucagon cuases breakdown of glycogen into glucose increasing the blood glucose level to normal. This is feedback mechanism that is operative not only at cellular level in ecological system of tje biosphere as well. When homoestasis does not function properly it affects the physiology of the cell as well as entire organism. For example diabetic patient cannot control its blood sugar level due to deficiency of insulin hormone hence cannot maintain homeostasis of blood sugar and needs input of jnsulin from outside and if not provided it would lead to several health issue even sometimes to death.

==>The organizational levels beginning from atom are as:-

ATOM-MOLECULE--ORGANELLE-CELL-TISSUE-ORGAN-ORGANISM.

==>The metabolism is the sum total of anabolism and catabolism.

Anabolism is the process in which large comples molecules are synthesised from simple ones for constructive metabolism for example photosynthesis

CO2 + H20------->Glucose

Catabilism is the reverse of anabolism where complex molecules breakdown into simpler ones for example respiration.

Glucose - - - - - - > H20+ CO2 + Energy
