Question

(check all that apply)
active transport is different from passive transport because

□ active transport requires atp energy.

□ active transport does not need a protein present in order to take place.

□ active transport moves molecules from areas of low concentration to areas of high concentration using a protein.

□ active transport does not require energy.

□ active transport moves molecules from area of high concentration to areas of low concentration.

Explanation:

Active transport requires ATP energy to move molecules against the concentration gradient (from low - to high - concentration areas) with the help of transport proteins. Passive transport moves molecules along the concentration gradient (from high - to low - concentration areas) and does not require ATP energy. Some passive transport (facilitated diffusion) may use proteins, but not all.

Answer:

• Active Transport requires ATP energy.
• Active Transport moves molecules from areas of LOW concentration to areas of HIGH concentration using a protein.
