Question

The acid-soluble pool represents roughly the cytoplasmic composition which of the following nutrient is most likely absent in it?

• A. Lecithin
• B. Calcium ions
• C. Adenosin
• D. Glucose

Answer 1

The correct option is B

Calcium ions

The correct option is B:

Explanation of correct option:

1. The majority of organic compounds are soluble in acid and subsequently filtered out, forming the filtrate.
2. It's referred to as an acid-soluble pool.
3. The acid-soluble pool may be devoid of inorganic components.
4. Organic molecules (mainly monomers) such as lecithin, adenosine, and glucose are likely to be found in acid-soluble pools.
5. As a result, calcium is less likely to be present in an acid-soluble pool.

Explanation of incorrect options:

Option A:

1. Lecithin is a lipid combination that is necessary for human cells to function.
2. Lipids are included in the acid-soluble pool because their molecular weight meets the criterion for molecules in the acid-soluble pool.

Option C:

1. Human cells contain the chemical adenosine.
2. Adenosine, adenosine monophosphate (AMP), and adenosine triphosphate are the three types of adenosine (ATP).
3. It is freely soluble in hot water and soluble in 1 N hydrochloric acids and therefore, can be found in the acid-soluble pool.

Option D:

1. Glucose crystallizes into white or colorless crystals that are extremely soluble in water and acetic acid, but not in methanol or ethanol.
2. It is a carbohydrate and is present in the acid-soluble pool.

Final answer: The acid-soluble pool represents roughly the cytoplasmic composition, calcium ions are unlikely to present in it.
