Question
Metabolism typically couples endergonic and exergonic reactions Why? Are the overall bioenergetics of these coupled reaction endergonic exergonic or neutral? Explain. The Theory of Evolution by Natural Selection is sometimes paraphrased at "survival of the fittest." How is fitness measured or defined? What Panera or monogenetic inheritance is exhibited by the pedigree above? Be specific your identification: identify if the trait in question is autosomal, Y-linked, or X-linked. Also, identify whether the trait is dominant or recessive, incompletely dominant co-dominant or epigenetic as appropriate. The mating pair in generation IV (see arrow) in the pedigree above is expecting another child. What is the probability of this child being an unaffected (not expressing or carrying the allele in question) female? (Show now work).Explanation / Answer

Cell theory:
According to cell theory, cells have size limitation because every cell has its own surface area to volume ration that determines its individual functional effects such as metabolic activities including enzymatic reactions to generate energy & to sustain cell life. In unicellular giant cells normally all reactions performed by a single cells therefore only one cell determines the life of the cell where as in solution of multicellular organisms is better than a single giant cell because multicellular organisms composed various cells together to form a functional tissue to carry out various metabolic activities with regeneration capacity.
These cells normally exchange oxygen and CO2 to perform catabolic and anabolic activities to generate energy. These cells exchange metabolic waste materials and heat energy to keep the cell at living condition at biological temperature and pressure. Cell size has determined by the cell genome and DNA of the nucleus at the time of mitosis or reduction division. Gene expression of each cell determines the synthesis of enzymatic proteins to carryout cell functions in both single cell and multicellular species with meticulous differences. Therefore, cell differentiation affected & determined by the enzymatic synthesis and gene expression.
Ques-58:
Metabolism is typically coupled to endergonic and exergonic reactions to mediate enzymatic reactions finally to generate energy to perform physiological functions of the body as a result homeostasis can be attained inside & outside the cell. Most of the coupled reactions associated with both catabolic and anabolic reaction to derive energy and to perform metabolic reactions within the cells. For example catabolic coupled reactions are involving enzymatic action on various polymer molecules to break down and to generate energy in the form of ATP to support anabolic activities therefore these are exergonic coupled reactions. Anabolic endergonic reaction coupled with the usage of the cellular energy ATP to generate complex macromolecules from simple monomers.
