Question 14

Absorption via diffusion
(2)

Answer 14

• The net movement of substrates form an area of high concentration to an area of low concentration
• PASSIVE PROCESS

Question 15

Facilitated diffusion
(2)

Answer 15

• Invloves a carrier protein
• PASSIVE PROCESS

Question 16

Active transport
(3)

Answer 16

• Substances are moved against the concentration gradient
• Requires a supply of energy
• This comes from ATP

Question 17

Co-transport
(3)

Answer 17

• a special type of transport
• Monosaccharides move across the epithelium of the small intestine into the capillaries in this way
• Disaccharide’s and polysaccharides are too large
