digestion

Question 1

cells lining the ileum of mammals absorb the monosaccharide glucose co-transport with sodium ions explain how

Answer 1

sodium ions are actively transported from ileum to blood
maintaining the gradient
glucose enters by facilitated diffusion with sodium

Question 2

explain advantages of lipid droplet and micelle formation

Answer 2

increase surface area
faster hydrolysis
micelles carry fatty acids and glycerol

Question 3

how is golgi involved in absorption of lipids

Answer 3

modifies triglycerides
combines triglycerides with proteins
packages for release

Question 4

describe the processes involved in the absorption and transport and digested lipid molecules from the ileum to lymph vessels

Answer 4

micelles contain bile salts and fatty acids
make fatty acids soluble
fatty acids absorbed by diffusion
triglycerides reform on cells
vesicles move the cell membrane

Question 5

describe the mechanism for the absorption of amino acids in the ileum

Answer 5

facilitated diffusion of amino acids
co transport
sodium ions actively transported from cell to blood
creating sodium ion concentration gradient
