Why is the caloric value of some sugar alcohols less than 4 kcal/g? a. They cannot be transported into the mitochondria. b. None
avanturin [10]

Answer:

Option-C

Explanation:

The sugar alcohols are the carbohydrates which are neither considered sugars nor alcohols but they partially resemble the structure of both of these sugars and alcohol.

The sugar alcohols are naturally present in the vegetables and fruits but they are also artificially synthesised like xylitol, lactitol, mannitol and others.

They are considered the alternative from of sugar but they provide less energy as compared to carbohydrates like they provide about 0-3 kcal per gram whereas sugar provides 4 kcal per gram.

This difference is due to the reason that they are not completely absorbed by the human body and also they are incompletely metabolized therefore provide less energy.

Thus, Option-C is the correct answer.

Describe the four structural roles of the skeletal system.<br> The Human SKELETAL SYSTEM
makkiz [27]

Answer:

1. Support

2. Protection

3. Movement

4. Supply & Storage

Explanation:

1. Support :  It provides a framework to support the organs and tissues of the body.  

2. Protection:  It protects our internal organs.  The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).

3. Movement:  It provides a framework for muscles to attach.  Then when the muscles contract they pull on the bones of the skeleton, which act like levers to create movement.

4. Supply & Storage:  The bones that make up the skeleton are a source of both red blood cells (which transport oxygen) and white blood cells (which fight infection), which are formed within the bone marrow.
