When drugs are swallowed, they may be broken down (metabolized) by enzymes and/or absorbed using. transporters in cells found in the small intestine. Grapefruit juice can cause problems with these enzymes. and transporters, causing too much or too little drug in the body. Some drugs, like statins used to lower cholesterol, are broken down by enzymes.
Monocots. Monocotyledonous leaves show a parallel venation and mostly are arrow or band-shaped. Stomata and other epidermal cells are almost always arranged in parallel arrays. These characterics are depicted in the photographs below of maize, papyrus and yucca.How monocotyle leaves develop is further explained in the section on monocot leaf formation.onocotyledonous leaves show a parallel venation and mostly are arrow or band-shaped.

Many of the most important food crops are examples of plants with monocot seeds including wheat, rice, and corn. Monocots have one cotyledon or embryonic leaf in their seeds differentiating them from dicots that have two. Monocot flowers have floral parts grouped in threes: parallel leaf veins, pollen grains with one pore or furrow and vascular bundles throughout the stem's tissue. As a food crop grown for more than 12,000 years, agronomists believe that wheat originated in southwestern Asia.
