Which of the following statements about gluconeogenesis in animal cells is true?
MakcuM [25]

Answer:

C. THE CONVERSION OF FRUCTOSE 1,6-BISPHOSPHATE to fructose- 6- phosphate is not catalyzed by phosphofructokinase -1, the enzyme involved in glycolysis.

Explanation:

This statement is true as the enzyme involved in this step is FRUCTOSE-1,6-BISPHOSPHATASE.

Gluconeogenesis is the coversion of non-carbohydrate molecules (lactic acid, amino acids, glycerol) through the pyruvic acid into glucose in the cells.

This process takes place mainly in the liver and occurs during periods of fasting, starvation, low carbohydrate diets.

The pathway of gluconeogenesis involves eleven steps of enzymatic catalyzed reactions.

In the conversion of fructose 1,6- bisphosphate to fructose-6-phosphate is catalyzed by fructose 1,6-bisphosphatase and not by phosphofructokinase -1 which is involved in glycolysis. This step is a rate-limiting step of the pathway.

The conversion of glucose-6-phospahte to glucose is not catalyzes by hexokinase but glucose -6- phosphatase.

What's the answer to this question
Flauer [41]
The answer is C. Thermal energy is transferred to her face by radiation, and thermal energy is transferred to the bottoms of her feet by conduction. 

Conduction is a method of transferring heat by using the collision of molecules and free electrons (depending on the material). Heat is usually transferred by conduction if both objects are in contact with each other that way the molecules can collide and spread the kinetic energy thus raising their internal heat. So, since the feet and the sand are in contact, so the heat should be transferred by conduction. However, air is a very poor heat conductor, it cannot transfer heat efficiently, therefore, the first answer is not conduction. 

Radiation is a method of transferring heat too but using electromagnetic waves. It works great even in the air, or even with vacuum space. The sun shining from outer space to earth through the vacuum space is also by radiation. So, the first answer is radiation. 

The answer is C, hope it helps!
