Which of the following is/are correct regarding the pentose phosphate pathway? I. NADH is generated by the oxidation of glucose-
fgiga [73]

Answer:

The correct answer is 1 NADH is generated by the oxidation of glucose-6-phosphate.

Explanation:

Pentose phosphate pathway deals with the utilization of glucose-6-phosphate by oxidation process to form 6-phosphogluconolactone by the catalytic activity of glucose-6-phosphate dehydrogenese.

   This enzyme need NAD+ as co enzyme which get reduced to generate NADH.

Which statement is true for an open system?
Bingel [31]

Answer:

Before we get into the first law of thermodynamics we need to understand the relation between heat and work and the concept of internal energy. Just like mass, energy is always conserved i.e. it can neither be created nor destroyed but it can be transformed from one form to another. Internal energy is a thermodynamic property of the system that refers to the energy associated with the molecules of the system which includes kinetic energy and potential energy.

Whenever a system goes through any change due to interaction of heat, work and internal energy, it is followed by numerous energy transfer and conversions. However, during these transfers, there is no net change in the total energy.

Similarly, if we look at the first law of thermodynamics it affirms that heat is a form of energy. What it means is that the thermodynamic processes are governed by the principle of conservation of energy. The first law of thermodynamics is also sometimes referred to as the Law of Conservation of Energy

What is the change in enthalpy when 4.00 mol of sulfur trioxide decomposes to sulfur dioxide and oxygen gas? 250 2(g) + O2(g) ®
lidiya [134]

Answer: A. -396 kJ

Explanation:

The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.

2SO_2(g)+O_2 (g)\rightarrow 2SO_3(g)  \Delta H^0=198kJ

Reversing the reaction, changes the sign of \Delta H

2SO_3(g)\rightarrow 2SO_2(g)+O_2 (g)  \Delta H^0=-198kJ

On multiplying the reaction by 2, enthalpy gets multiplied by 2:

4SO_3(g)\rightarrow 4SO_2(g)+2O_2 (g)   \Delta H=2\times -198kJ=-396kJ

Thus the enthalpy change for the reaction 4SO_3(g)\rightarrow 4SO_2(g)+2O_2 (g)  is -396 kJ.
