Autonomic function control. If the dietary carbohydrates do not meet the energy needs of the body, protein and glycerol from dietary and endogenous sources are used by the body to maintain glucose homeostasis. Figure 3: Impact of intra-abdominal fat on plasma glucose-insulin homeostasis Figure 3: Impact of intra-abdominal fat on plasma glucose-insulin homeostasis One of the major conditions caused by excess intra-abdominal adipose tissue is insulin resistance, defined as the inability of insulin to perform many of its major metabolic functions. Family history and genes play a role in type 2 diabetes. Active immunity involves the production of antibodies by the body itself and the subsequent development of memory cells Passive immunity results from the acquisition of antibodies from another source and hence memory cells are not developed Active immunity will result in long-term immunity but passive immunity will not. Use a model to illustrate that aerobic cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and new bonds form, resulting in new compounds and a net transfer of energy. Homeostasis definition, the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function. On successful completion of the MBBS program, graduates will be able to: Recognize the normal structure and function of the human body (as an intact organism) and of each of its major organ systems, taking cognizance of the molecular, biochemical, and cellular mechanisms that are important in maintaining the body’s homeostasis. Concept If you were to insert a hollow tube of a certain diameter into a beaker of water, the water would rise inside the tube and reach the same level as the water outside it. We have proposed a modification of the GAS concept of Selye (1936) to reflect the progress in seed molecular biology and biochemistry over the last few decades. The outstanding stress resistance at certain stages in the seed life cycle and their vulnerability at other stages make seeds very attractive for the development of stress concepts.
