***A*** ∻Key Concept∻ ⚹Active Transport Requires Energy⚹ ∻Explanation∻ ⚹Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. This process requires energy, often in the form of ATP, because it is moving substances against their natural direction of movement.⚹◊How do cells utilize active transport to maintain homeostasis?⍭ Generate me a similar question◊
