Which equation is an expression of the second law of thermodynamics for a spontaneous process?.
leva [86]

The second law of thermodynamics states that a spontaneous process increases the entropy of the universe, S(univ) > 0. If ΔS(univ) < 0, the process is nonspontaneous, and if ΔS(univ) = 0, the system is at equilibrium

<h3>What is thermodynamics ?</h3>

The science of thermodynamics examines the connections between heat, work, temperature, and energy. The rules of thermodynamics explain how energy moves inside a system and whether or not the system is capable of performing beneficial work on its surroundings.

  • Energy cannot be generated or destroyed, according to Thermodynamics' First Law. The entropy of the cosmos increases for spontaneous processes, according to the second law of thermodynamics. Third Law of Thermodynamics: Entropy is zero in a flawless crystal at absolute zero Kelvin.

Polysaccharide digestion and glycogen breakdown involve sequential cleavage from ________ ends of glucose polymers.
Alex787 [66]

Sequential cleavage from the non-reducing terminals of glucose molecules is required for both glycogen degradation and polysaccharides hydrolysis.

Why non-reducing end is selected for digestion?

A polysaccharide's non-reducing end is the one where an anomeric carbon participates in the glycosidic connection. The elimination of carbohydrate remnants one at a time out from the non-reducing terminal occurs during glycogenolysis and polysaccharides hydrolysis.

  • For example, several enzymes are involved in glycogenolysis in the liver and muscle.
  • An example of such an enzyme is glycogen phosphorylase, which catalyzes the successive dissociation of the alpha 1->4 glycosidic bond that connects two glucose molecules at a non-reducing terminal of glycogen. The last glucose residue is eliminated as alpha-D-glucose 1-phosphate.

That is why non-reducing end of glucose is chosen for digestion or breakdown of the carbohydrate polymer.
