Some time after the digestion of a meal the concentration of glucose in the intestine can be lower than the concentration in the blood. However, glucose still passes into the blood. This occurs by:

•  active transport

• diffusion

• osmosis

• peristalsis

Which cell structure is responsible for making proteins?

• cell wall

• ribosome

• cell membrane

• nucleus
