Test: Sources of Carbohydrates, Lipid/Fat, Protein - JAMB MCQ

Glucose is a monosaccharide, which means it is a simple sugar consisting of a single sugar unit. Starch, cellulose, and glycogen are complex carbohydrates or polysaccharides made up of multiple sugar units.

Starch is a complex carbohydrate made up of many glucose units bonded together. Fructose, lactose, and sucrose are simple sugars or carbohydrates composed of one or two sugar units.

Olive oil is a source of unsaturated fats. Unsaturated fats are considered healthier fats and are usually liquid at room temperature. Butter, coconut oil, and beef fat are sources of saturated fats, which are typically solid at room temperature and are considered less healthy when consumed in excess.

Amino acids are the building blocks of proteins. Proteins are large biomolecules composed of long chains of amino acids, which are connected by peptide bonds. Nucleotides are the building blocks of nucleic acids (DNA and RNA), fatty acids are the building blocks of lipids, and monosaccharides are the building blocks of carbohydrates.

Chicken is a complete protein source. Complete proteins contain all the essential amino acids required by the body. Rice, beans, and corn are incomplete protein sources as they lack some essential amino acids.

Lactose is a simple sugar. Simple sugars, also known as monosaccharides or simple carbohydrates, consist of a single sugar unit. Glycogen and cellulose are complex carbohydrates or polysaccharides, and sucrose is a disaccharide.

Eggs are an animal source of protein. They are a complete protein source and provide a good balance of essential amino acids. Lentils, tofu, and almonds are plant-based sources of protein.

Energy storage is a function of carbohydrates in the body. Carbohydrates are the body's primary source of energy. They are broken down into glucose, which is used by cells for various metabolic processes. Carbohydrates do not provide insulation, serve as a component of cell membranes, or transport oxygen in the blood.

Cheese is a source of saturated fats. Saturated fats are usually solid at room temperature and are considered less healthy when consumed in excess. Avocado, salmon, and sunflower oil are sources of unsaturated fats, which are generally considered healthier fats.

Soybeans are an incomplete protein source. Incomplete proteins lack one or more essential amino acids. Beef, quinoa, and milk are complete protein sources as they provide all the essential amino acids required by the body.
