1. Absorption Of Products Of Digestion

Question 1

What are the products of digestion ?

Answer 1

Monosaccharides

Monoglycerides and fatty acids

Amino acids

Question 2

How is glucose transported across membrane into blood?

Answer 2

Active transport with sodium ions via co transporter protein

Galactose the same way with same protein

Question 3

How is fructose transported across membrane into blood ?

Answer 3

Facilitated diffusion through a different transporter protein

Question 4

What helps move monoglycerides and fatty acids towards epithelium?

Answer 4

Micelles

As they constantly break up and reform they release monoglycerides and fatty acids allowing them to be absorbed.

Whole micelles not taken up but MG and FA are lipid soluble so can diffuse directly across

Question 5

How to amino acids transport across membrane into

Blood?

Answer 5

Active transport with sodium’s ions through co transporter proteins

Question 6

Visking tubing

Answer 6

Partially permeable

Allows small soluble molecules like water to pass through not not large ones like proteins
