The correct Answer is:
To solve the question of which lists include one or more molecules that always contain nitrogen atoms, we will analyze each list step by step.
### Step 1: Analyze List I
- **Molecules in List I**: Glucose, Cholesterol, Triglycerides, Water
- **Glucose**: A monosaccharide (sugar) that does not contain nitrogen.
- **Cholesterol**: A type of lipid that does not contain nitrogen.
- **Triglycerides**: A type of fat (ester) that does not contain nitrogen.
- **Water**: A simple molecule (H2O) that does not contain nitrogen.
**Conclusion for List I**: None of the molecules in List I contain nitrogen.
### Step 2: Analyze List II
- **Molecules in List II**: Glucose, Antibodies, Adenine, Phospholipids
- **Glucose**: As previously stated, does not contain nitrogen.
- **Antibodies**: Proteins that are made of amino acids, which always contain nitrogen (NH2 group).
- **Adenine**: A nitrogenous base that is part of nucleotides and contains nitrogen.
- **Phospholipids**: Do not contain nitrogen.
**Conclusion for List II**: Antibodies and Adenine in this list contain nitrogen.
### Step 3: Analyze List III
- **Molecules in List III**: Hemoglobin, Carbon Dioxide, mRNA, Monosaccharides
- **Hemoglobin**: A protein that carries oxygen and contains nitrogen.
- **Carbon Dioxide**: A simple molecule (CO2) that does not contain nitrogen.
- **mRNA**: A type of nucleic acid made of nucleotides, which contain nitrogenous bases, thus mRNA contains nitrogen.
- **Monosaccharides**: Simple sugars that do not contain nitrogen.
**Conclusion for List III**: Hemoglobin and mRNA in this list contain nitrogen.
### Final Conclusion
- **List I**: No nitrogen-containing molecules.
- **List II**: Contains nitrogen (Antibodies and Adenine).
- **List III**: Contains nitrogen (Hemoglobin and mRNA).
Thus, the lists that include one or more molecules that always contain nitrogen atoms are **List II and List III**.
### Answer
**The correct answer is: 2 and 3 only.**

Read the passage given below and answer the question: Adenosine triphosphate (ATP) is the energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine, the sugar, ribose, and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis). Usually only the outer phosphate is removed from ATP to yield energy, when this occurs ATP is converted to adenosine diphosphate (ADP), the form of the nucleotide having only two phosphates. The importance of ATP (adenosine triphosphate) as the main source of chemical energy in living matter and its involvement in cellular processes has long been recognized. The primary mechanism whereby higher organisms, including humans, generate ATP is through mitochondrial oxidative phosphorylation. For the majority of organs, the main metabolic fuel is glucose, which in the presence of oxygen undergoes complete combustion to CO_2 and H_2O : C_6H_(12)O_6 + 6O_2 rarr 6CO_2 + 6H_2O + "energy" The free energy (AG) liberated in this exergonic (AG is negative) reaction is partially trapped as ATP in two consecutive processes: glycolysis (cytosol) and oxidative phosphorylation (mitochondria). The first produces 2 mol of ATP per mol of glucose, and the second 36 mol of ATP per mol of glucose. Thus, oxidative phosphorylation yields 17-18 times as much useful energy in the form of ATP as can be obtained from the same amount of glucose by glycolysis alone. The efficiency of glucose metabolism is the ratio of amount of energy produced when 1 mol of glucose oxidised in cell to the enthalpy of combustion of glucose. The energy lost in the process is in the form of heat. This heat is responsible for keeping us warm. (source: Erecińska, M., & Silver, 1. A. (1989). ATP and Brain Function.

Carbohydrates play a vital role in our daily life. These are classified as monosacchrides, oligosaccharides and polysaccharides depending upon the number of smaller molecules on hydrolysis. It has been suggested that monosaccharides do not have a free aldehyde or ketonic group but have cyclic hemiacetal or hemiketal structures. D - Glucose exists in two isomeric stereoisomeric forms : alpha-D- glucose and beta-D glucose which have different positions of H and OH groups on first carbon atom. Disaccharides such as sucuose, maltose, lactose, etc., give monosaccharides on hydrolysis. Polysaccharides are starch, cellulose, glycogen, having molecular formula (C_(6)H_(10)O_(5))_(n) . Name the water insoluble component of starch.
Monosaccharides are polyhydric aldehydes and ketones which cannot be hydrolysed into simpler carbohydrates. The monosaccharides containing -CHO group are called aldoses while those containing C=O group are called ketoses. The aldehyde group is always present at C_(1) while keto group is generally present at C_(2) . All monosaccharides are oxidised by Tollen's reagent and Fehling solution and are called reducing sugars. The monosaccharide molecules may be assigned D and L-configurations depending upon whether the configuration of the molecule is related to D- or L-glyceraldehyde. If the -OH group is attached to the carbon adjacent to the -CH_(2)OH group (last chiral carbon) is on the right hand side, it is assigned D-configuration. The molecule is assigned L-configuration if the -OH group attached to the carbon adjacent to the -CH_(2)OH group is on the left. The monosaccharides contain one or more chiral carbon atoms. Pentoses and hexoses have cyclic structures furanose (five membered) and pyranose (six membered). During cyclization, C_(1) in aldohexoses and C_(2) in fructose become chiral and the newly formed -OH group may be either on the left or on the right in Fischer projection formulae. These monosaccharides, therefore, exist in two stereoisomeric forms called alpha -anomer and beta -anomer while C_(1) and C_(2) are called glycosidic or anomeric carbon. The bonds joining glycosidic carbon are called glycosidic linkages. D(+) glucose exists in two stereoisomeric forms, alpha -D- glucose and beta -D-glucose. When either of these two forms of glucose i.e., alpha-D- glucose are dissolved in water and allowed to stand, these get slowly converted into other form and an equilibrium mixture of both is formed. This process is called mutarotation. The maximum number of optical isomers of glucose expected are
