Significance of the birds in the old man
Research studies suggest that a high-fiber diet protects against colon cancer. This is because high fibrous food increases the bulk in the digestive tract to pass easily through the intestinal tract to shorten the time of passage. This short time of passage of food reduces the interaction of carcinogens present in the food with the intestinal tract. The fibers are broken down in butyrate by the bacteria present in the lower intestine. This butyrate inhibits the growth of tumors of colon and rectum,
Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
