Question

1)The enterohepatic circulation reabsorbs bile salts in the distal portion of the small intestine (ileum). All of the following statements about the enterohepatic circulation are true except one. Select the statement below that is NOT true of the enterohepatic circulation? A) Reabsorbing bile salts in the ileum gives more time to emulsify lipid and aid in their absorption within a greater length of the small intestine. B) The reabsorption of bile salts allows them to be reused within new bile. C) All of the components of bile are recycled by this circulation. D) Reabsorption of bile salts reduces the need to synthesize new bile salts. 2) Which of the following is the best illustration of the difference between metabolism and digestion? A) Digestion has a wide variety of chemical reactions while metabolism is restricted to only a few reaction types. B) Digestion requires enzymes for it to take place while metabolism does not necessarily need or use them. C) Metabolism comprises all of the chemical reactions preformed within the body while digestion is only the breakdown of food within the GI tract. D) Digestions must happen first for metabolism to follow it. 3) Which of the following is least involved in the mechanical breakdown of food, digestion, or absorption? A) large intestine B) the oral cavity C) the esophagus D) the small ingestion 4 Which of the following is the best explanation for why the cells of the proximal convoluted tubule (PCT) contain so many mitochondria? A) A great deal of active transport takes place in the PCT.

Answer 1

1. Answer ; C) All of the component of bile are recycled by the circulation.

Reason ; Among the four given statement, except the above mentioned statement all the steament are true about the enterohepatic circulation, cause all of the components aof the bile are not get recycled in the circulation. Hence the above statement is the appropriate answer.

2. Answer ; C) metabolism comprises all of the chemical reaction performed within the body while digestion is nonly the breakdown of food within the GI tract.

Reason ; Within the given statement the above mentioned statement is the only statement which explains the actual differnce between the digestion and the metabolism, cause these process is interrelated to one another. Other statement are not a actual fact about these process.

3. Answer ; C) the esophagus

Reason ; Among the given option, the above mentioned part is the region where the mentioned process including in the digestion are take place in a less amount, cause this part act as a channel for these process.
