How is carbohydrate consumed in excess converted to fat?
a. Directly, by incorporating the glucose into the triglyceride
b. Indirectly, by converting glucose to acetyl CoA
c. Directly, by converting glucose to fatty acid molecules
d. Indirectly, as a by-product of gluconeogenesis

Indirectly, by converting glucose to acetyl CoA.

Explanation:

When excess carbohydrate is consumed it gets converted to glycogen or fatty acids.

The glucose stores fatty acids by the process of lipogenesis. In this process the end product of glycoloysis ie pyruvate is converted to acetyl CoA. This triglyceride stores the fat in adipose tissues.

In the time of need glucose is brought to use by glycogenolysis and gluconeogenesis.

So, the excess fat gets converted and stored as long chain fatty acid and gets incorporated in phospholipids, cholestrol  and triacyglycerol.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

6.4 cm (max) - 25 cm (min)
