    Which are the most common types of lipids?

    • A.

      Steroids

    • B.

      Carbohydrates

    • C.

      Fats

    • D.

      Enzymes

    Correct Answer
    C. Fats
    Explanation
    Fats are one of the most common types of lipids. Lipids are a diverse group of molecules that include fats, steroids, and phospholipids. Fats, also known as triglycerides, are composed of glycerol and fatty acids. They are an important source of energy in the body and play a crucial role in insulation, protection of organs, and absorption of fat-soluble vitamins. Steroids, on the other hand, are a class of lipids that include hormones like testosterone and cholesterol. Carbohydrates and enzymes are not lipids.

    What is the function of enzymes?

    • A.

      Form genes

    • B.

      Catalyze specific chemical reactions

    • C.

      Carries out protein synthesis

    • D.

      Build cell structures

    Correct Answer
    B. Catalyze specific chemical reactions
    Explanation
    Enzymes are proteins that act as catalysts in biological reactions. They speed up the rate of chemical reactions by lowering the activation energy required for the reaction to occur. Enzymes are highly specific, meaning that each enzyme catalyzes a particular chemical reaction. They do not form genes, carry out protein synthesis, or build cell structures. Instead, enzymes play a crucial role in catalyzing specific chemical reactions in cells.

    RNA has a sugar called 

    Correct Answer
    ribose

    RNA has a sugar called ribose. Ribose is a monosaccharide sugar that is a key component of RNA molecules. It is a five-carbon sugar that forms the backbone of the RNA molecule. Ribose is essential for the synthesis and functioning of RNA, as it provides the necessary structural support for the molecule. This sugar is different from the sugar found in DNA, which is called deoxyribose.

Blood is approximately 92% water, and bodily fluids such as saliva, urine, and sweat also contain a high percentage of water. Water is essential for various bodily functions, including transporting nutrients and oxygen, regulating body temperature, lubricating joints, and removing waste products. Without an adequate amount of water, the body cannot maintain proper hydration and function optimally.
