To determine: The irreversible process in terms of the entropy changes in the system, surroundings, and the universe is to discuss where there is a system consisting of an egg in an incubator; the white and yolk of the egg contains proteins, carbohydrates, and lipids, and if the egg is fertilized, the complex organism is formed from a single cell.
Introduction:
The “system” is defined as the region where the molecules react with other and are collectively differ from surroundings. The region of the universe minus the system is called “surroundings”.

Explanation of Solution
Explanation:
The fertilization of egg and formation of mature chick is the complete series of reactions.
The system is considered as egg and its related developmental reactions. The yolk, eggshell and region aorta from egg are collectively termed as surroundings.
The division of single cell and formation of multiple cells increases the order of reaction. The increase in order of reaction reduces the system ‘entropy.
The molecules acting as fuel in surroundings has low entropy and gradually they convert to smaller molecules, such as water and carbon dioxide. The entropy is increased in surroundings. There is a significant difference in entropy decreased of chick and entropy increased of surroundings.
Conclusion:
The egg divides and multiple cells are formed that differentiate and form mature chick. The entropy is decreased of chick and the entropy increases of surroundings.

- Map out all of the metabolic pathways in the liver cell. Draw out the structures and names of all compounds neatly by hand and the pathways responsible for metabolizing them. Some examples are: Glycolysis/gluconeogenesis, PPP, Glycogenesis/glycogenolysis, Krebs, ETC, selectamino acid pathways (Ala, Glu, Asp) Lipogenesis/lipolysis. Citrate/MAS/glycerol phosphate shuttlesystems, and the Cori/Glc-Ala cycles. Rules:-Draw both a mitochondrial area of metabolism and a cytoplasmic area of metabolism.-Draw the liver and its roles in glucose recycling (Cori cycle/Glc-Alanine recycling)-Avoid drawing the same molecule twice (except for separate mitochondrial/cytoplasmic populations. i.e. Design the PPP/Glycolysis so that GAP is only drawn once)-Label Carbon 4 of glucose and highlight where you would expect to find it in EVERY compound in whichit is present.-Have one or two locations for NADH/NADPH/ATP/GTP/CoQH2 – many arrows will come to/from thesespots.arrow_forwarda. Draw the Krebs Cycle and show the entry points for the amino acids Alanine,Glutamic Acid, Asparagine, and Valine into the Krebs Cycle. (Include name of Enzymes involved) b.

Phosphate is a substrate for Complex V (the ATP Synthase), the enzyme that couples the synthesis of ATP to the H+ gradient formed by the electron transport chain. (a) Bongotoxin is a hypothetical compound that inhibits the phosphate translocase of the inner mitochondrial membrane. Explain why electron transport from NADH to O2 stops when bongotoxin is added to mitochondria (i.e., why do electrons stop flowing through the electron transport chain even with an abundance of NADH and O 2 present). What effect will the addition of the weak acid dinitrophenol (DNP) to the cytosol have on electron transport in bongotoxin-inhibited mitochondria? Be sure to explain your answers.

It is converted enzymatically to fluoroacetyl-CoA and is utilized by citrate synthase to generate (2R,3S)-fluorocitrate.
