D)chloroplast
Answer: Option A .
In a coil by Hydrogen bonding.
Explanation:
B - pleated sheet secondary structure of protein is a regular element of secondary protein structure which consist of beta strands. In B pleated sheet, two or more segments or strands of polypeptide chain lie at the side of each other to form sheet which is held by Hydrogen bonding. The G in B pleated sheet form a coil and are held by Hydrogen bonding. This bond is formed by carbonyl and amino acid group.
Answer:
The correct answer is ''They are reabsorbed in the ileum.''
Explanation:
Bile salts are the fundamental constituent of bile, solubilizing dietary lipids so that they can be absorbed. Bile salts are the main products of cholesterol degradation and are poorly absorbed by passive diffusion in the proximal portion of the small intestine and most of the intestinal bile salts are reabsorbed in the terminal ileum, which actively absorbs 90 % of bile salts to the portal venous circulation, which returns them, again, to the hepatocytes that conjugate and excrete, again, the bile into the gallbladder. Bile salts circulate through this pathway from the liver to the intestine and again to the liver (enterohepatic circulation) between 10 and 12 times a day.
