Accepted Answer

### Question 3
# Brief Explanations:
- Option a: Carbs (carbohydrates) are made of monosaccharides, amino acids are monomers of proteins—incorrect pairing.
- Option b: Lipids include fats, and fatty acids are components of lipids (e.g., in triglycerides, fatty acids are part of the lipid structure)—correct pairing.
- Option c: Proteins are made of amino acids, glucose is a carbohydrate monomer—incorrect pairing.
# Answer: B. Lipids and Fatty acids

### Question 4
# Brief Explanations:
Carbohydrates (like glucose) are broken down to release energy quickly and are the primary energy source for cells and living organisms. Lipids are long - term energy storage, proteins are for structure/enzymes, and nucleic acids are for genetic info.
# Answer: Carbohydrates

### Question 5
# Brief Explanations:
Polymers are large molecules made by linking many smaller monomer units (e.g., proteins are polymers of amino acid monomers, carbohydrates are polymers of sugar monomers). So monomers do make up polymers.
# Answer: True

### Question 6
# Brief Explanations:
Lipids are non - polar molecules. Water is polar, so lipids do not mix with water (hydrophobic). Carbohydrates, proteins, and nucleic acids are generally hydrophilic or have hydrophilic regions.
# Answer: Lipids

### Question 7
# Brief Explanations:
1. **Dietary Intake**: Organisms (like humans) eat food containing proteins (e.g., meat, beans, eggs) and digest them into amino acids, then reassemble into their own proteins.
2. **Synthesis (for Autotrophs/Some Organisms)**: Plants (autotrophs) can synthesize proteins using amino acids made from inorganic nitrogen (like nitrate) and carbon skeletons from photosynthesis - derived sugars. For example, they combine amino acids to make enzymes or structural proteins.
# Answer: 1. Eating protein - rich foods (e.g., meat, beans) and digesting them into amino acids to build new proteins. 2. Synthesizing proteins from amino acids produced via metabolic pathways (e.g., plants using nitrogen and carbon sources to make amino acids then proteins).

### Question 8
# Brief Explanations:
Proteins are made of amino acids, and amino acids contain carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sometimes sulfur (S). So the elements in proteins are C, H, O, N (and S in some cases).
# Answer: Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N) (and sometimes Sulfur (S))

### Question 9
# Brief Explanations:
Lipids store long - term energy in the form of fat (triglycerides are a common form of lipid storage, with fatty acids and glycerol. Adipose tissue in animals stores triglycerides as fat for long - term energy).
# Answer: Fat (or Triglycerides)

### Question 10
# Brief Explanations:
Enzymes are biological catalysts, and most enzymes are proteins (a small number are RNA, but the majority are protein - based). So enzymes are proteins (a type of biomolecule).
# Answer: Proteins (most enzymes) (some enzymes are RNA, but protein - based enzymes are the most common answer here)

### Question 11
# Brief Explanations:
- Option a: Amino acids are monomers of proteins, not monosaccharides.
- Option b: Enzymes are proteins (or RNA), not monosaccharides.
- Option c: Glucose is a simple sugar (monosaccharide), the monomer of carbohydrates.
# Answer: C. Glucose

### Question 12
# Brief Explanations:
Cookies, candy, and cakes are rich in sugars (carbohydrates, especially simple sugars like sucrose in candy, or complex carbs that break down to sugars). They are sources of carbohydrates (specifically often simple carbohydrates or refined carbs).
# Answer: Carbohydrates (specifically often simple sugars or refined carbohydrates)

### Question 13
# Brief Explanations:
Nucleic acids (DNA and RNA) store and transmit genetic/hereditary information. DNA has the genetic code, and RNA helps in expressing that code (e.g., mRNA carries the code from DNA to ribosomes). Carbohydrates are for energy, lipids for energy storage, proteins for structure/enzymes.
# Answer: Nucleic Acids (DNA and RNA)

### Question 14
# Brief Explanations:
The monomer of a carbohydrate is a monosaccharide (e.g., glucose for starch, fructose, etc.). Fatty acids are monomers (or components) of lipids (like in triglycerides). So the statement is false.
# Answer: False

### Question 15
# Brief Explanations:
Carbohydrates are broken down quickly to provide short - term energy (e.g., glucose is used in cellular respiration for immediate energy). Lipids (like fats) are stored and can be broken down over time to provide long - term energy (they have more energy per gram than carbohydrates).
# Answer: Carbohydrates Provide short term energy, while Lipids provides long term energy

### Question 16
# Brief Explanations:
The cell membrane is a phospholipid bilayer. Phospholipids are a type of lipid (they have a hydrophilic head and hydrophobic tails). So the biomolecule that makes up the bilayer of the cell membrane is lipids (specifically phospholipids).
# Answer: Lipids (specifically Phospholipids)

### Question 17
# Brief Explanations:
1. **DNA (Deoxyribonucleic Acid)**: Stores genetic information in cells, has the instructions for an organism's development, function, and reproduction.
2. **RNA (Ribonucleic Acid)**: Involved in protein synthesis (e.g., mRNA carries genetic code, tRNA brings amino acids, rRNA is part of ribosomes).
# Answer: 1. DNA (Deoxyribonucleic Acid) 2. RNA (Ribonucleic Acid)

### Question 18
# Brief Explanations:
One main function of carbohydrates is to provide energy. For example, glucose is oxidized in cellular respiration to produce ATP (adenosine triphosphate), which is used by cells for work (like muscle contraction, active transport). They can also be used for structural purposes (e.g., cellulose in plant cell walls), but energy provision is a key function.
# Answer: Provide energy (e.g., glucose is broken down to make ATP for cellular processes)

### Question 19
# Brief Explanations:
In the central dogma of molecular biology, DNA is transcribed (copied) into mRNA (messenger RNA) in the nucleus. Then, mRNA is translated (in ribosomes) into proteins (polypeptide chains made of amino acids), which are the functional molecules (enzymes, structures, etc.) in the cell.
# Answer: DNA is transcribed into mRNA (messenger RNA) which is translated into proteins
