Which of the following secrete amylase?

Salivary glands and small intestine

Which of the following is used to keep the concentration of Na+ inside the epithelial cell low?

Active transport through the sodium-potassium pump

Secondary active transport through the Na+/glucose co-transporter

Facilitated diffusion through Na+ channels

Simple diffusion through the cell membrane

What is a similarity between active transport and passive transport?

Both move particles along the concentration gradient

Both move particles against the concentration gradient

What are the main differences between active and passive transport?

Active transport uses ATP and goes against the concentration gradient

Active transport uses ATP and and goes along the concentration gradient

Passive transport uses ATP and goes along the concentration gradient

Passive transport does not use ATP and goes against the concentration gradient

How does glucose leave the epithelial cell and enter the capillaries?

Facilitated diffusion through a membrane transport protein

Active transport through the membrane pump

Simple diffusion through the plasma membrane

How does the capillary network inside the villus provide an adaptation to absorption?

It maintains a high concentration gradient

It creates a long diffusion path

It transports fats around the body

What happens to fatty acids and monoglycerides once they enter the epithelial cell?

They are resynthesized into triglycerides by the smooth ER

They are resynthesized into triglycerides by the rough ER

They are packaged into lipoproteins and absorbed by the lacteal

They are packaged into lipoproteins and absorbed by the capillaries

How do non-polar triglycerides travel through the lymph system and the blood?

By being packaged into vesicles known as lipoproteins

By being packaged into vesicles known as cholesterol

By breaking back down into fatty acids and glycerol

Why is dialysis tubing a good model of the small intestine?

It is semipermeable and allows small molecules to diffuse in and out

It is semipermeable and allows large molecules to diffuse in and out

It is semipermeable and allows all molecules to diffuse in and out

It allows glucose, water and starch molecules to diffuse in and out

What is the muscle action that propels food through the gut?

Antagonistic muscle contraction
