16. Which one of the following is produced during the formation of photochemical smog?
(a) Hydrocarbons (b) Nitrogen Oxides
(c) Ozone (d) Methane

Ans: c

  • Photochemical smog is the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles, ground-level ozone and and peroxyacetyl nitrate (PAN).. This noxious mixture of air pollutants can include the following:
    • Aldehydes
    • Nitrogen oxides, such as nitrogen dioxide
    • Peroxyacyl nitrates
    • Tropospheric ozone
    • Volatile organic compounds

    All of these harsh chemicals are usually highly reactive and oxidizing. Photochemical smog is therefore considered to be a problem of modern industrialization. It is more common in cities with sunny, warm, dry climates and a large number of motor vehicles. Because it travels with the wind, it can affect sparsely populated areas as well.

Ans: c

Secretin and cholecystokinin are released from cells in the duodenal epithelium in response to acidic and fatty stimuli present there. (The duodenum /ˌdəˈdinəm/ is the first section of the small intestine )
  • An enterogastrone is any hormone secreted by the mucosa of the duodenum in the lower gastrointestinal tract in response to dietary lipids.(Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes)Examples include:
    • secretin
    • cholecystokinin
    • gastric inhibitory peptide
