Question

question 5 which transports molecules down their concentration gradients? passive transport active transport question 6 sugar molecules ____ diffuse through a lipid bilayer. can cannot

Explanation:

• For Question 5: Passive transport moves molecules from an area of higher concentration to an area of lower concentration (down the concentration gradient), while active transport moves molecules against the concentration gradient.
• For Question 6: Sugar molecules are polar and relatively large, and they cannot easily diffuse through the non - polar lipid bilayer without the help of transport proteins.

Answer:

Question 5: passive transport
Question 6: cannot
