Question

62. Choose the false statement:

A. One of the features that distinguishes amylose starch from glycogen is that the former is characterize by having only α-1,4 glycosidic linkages whereas in glycogen both α-1,4 and α-1,6 glycosidic linkages predominate.

B. One of the reasons that nervous tissues prefer glucose, as opposed to triglycerides, is that a gram of glucose generates more acetyl CoA than an equivalent amount of fat, both on a per carbon basis and per unit weight.

C. Saturated fats are usually solid at room temperature, whereas under similar conditions unsaturated fats would be liquid.

Answer 1

The answer is B. One of the reasons that nervous tissues prefer glucose, as opposed to triglycerides, is that a gram of glucose generates more acetyl CoA than an equivalent amount of fat, both on a per carbon basis and per unit weight.

This statement is false, the statements A and C are correct.

One gram of glucose generates less number of acetyl co. A than an equivalent amount of fat or both on a per carbon basis and per unit weight. the main reason behind why nervous cells glucoe as its main souce of enery is, if the nervouse system uses fats, it leads to promote oxidative stress, which leads and triggers the damage of cell membranes.
