Biomolecules in Chemistry Class 12

What are the main functions of carbohydrates in living organisms?

• Energy provision, energy storage, and structural support

• Regulating body temperature, supporting immune function, and aiding in digestion

What are the two main types of carbohydrates?

• Healthy carbohydrates and unhealthy carbohydrates

• Simple carbohydrates and complex carbohydrates

• Solid carbohydrates and liquid carbohydrates

• Fast carbohydrates and slow carbohydrates

What is the general formula for a carbohydrate?

• CO2

• H2O

• C6H12O6

• (CH2O)n

What are lipids and what are their functions in living organisms?

• Lipids are inorganic molecules that serve as enzymes in living organisms.

• Lipids are only found in plants and have no function in animal organisms.

• Lipids are primarily used for muscle contraction in living organisms.

• Lipids are organic molecules that serve as energy storage, insulation, and form the structure of cell membranes in living organisms.

What are the main types of lipids?

• Triglycerides, phospholipids, and sterols

• Saturated, unsaturated, trans fats

• Proteins, carbohydrates, vitamins

• Monosaccharides, disaccharides, polysaccharides

What are the differences between saturated and unsaturated fats?

• Saturated fats are healthier than unsaturated fats

• Saturated fats are found in plant-based oils, while unsaturated fats are found in animal products

• Saturated fats are always liquid at room temperature, while unsaturated fats are always solid

• Saturated fats are solid at room temperature and mostly found in animal products, while unsaturated fats are liquid at room temperature and mostly found in plant-based oils.

What are proteins and what are their functions in living organisms?

• Proteins are only responsible for providing energy in living organisms

• Proteins are only found in plants and not in animals

• Proteins are not made up of amino acids and do not have any specific functions in the body

• Proteins are essential molecules made up of amino acids that perform a wide variety of functions in living organisms, including acting as enzymes, hormones, and antibodies, as well as providing structural support and transport within the body.

What are the building blocks of proteins?

• Carbohydrates

• Amino acids

• Nucleotides

• Fatty acids

What is the primary structure of a protein?

• Linear sequence of amino acids in the polypeptide chain

• Three-dimensional shape of the protein

• Nucleotide sequence in the DNA

• Double helix structure

What are nucleic acids and what are their functions in living organisms?

• Nucleic acids are proteins and their functions include facilitating nerve transmission and supporting muscle contraction.

• Nucleic acids are the building blocks of DNA and RNA, and their functions include storing genetic information, transmitting genetic information, and controlling the synthesis of proteins.

• Nucleic acids are carbohydrates and their functions include providing energy for the cell and supporting cell structure.

• Nucleic acids are lipids and their functions include regulating body temperature and insulating the body.
