  • Fats are broken down into glycerol and fatty acids with a series of chemical reactions occurring in the digestive tract. The fatty acids are then absorbed through the small intestine and enter lacteals. The excess of such fatty acids gets converted into fats and are stored in the adipose tissue present in the subcutaneous layer. Under starvation, the fatty acids are mobilized to be used as energy during cellular respiration. These fatty acids during cellular respiration are first broken down into

    A
    Pyruvate
    B
    Succinate
    C
    Oxaloacetic acid
    D
    Acetyl Co-A

  • The following statements are based on the digestion and absorption of food. Select the correct and incorrect statements and choose an option accordingly from the codes given below. I. Active absorption of monosaccharides in the stomach and jejunum is carried out by facilitated transport. II. Most of the amino acids (above 95%) are absorbed in the duodenum and jejunum parts of the small intestine. III. Food is digested completely before absorption and is used by the body tissues. IV. Absorption of water from the small intestine is concerned with the absorption of salts and digested food in order to maintain an osmotic balance with the blood.

    A
    I, II and IV are correct, while III is incorrect
    B
    I, II and III are correct, while IV and V are incorrect
    C
    III, IV and V are correct, while I and II are incorrect
