Question

a primary active transport process is one in which ______. view available hint(s) molecules move through transport proteins that have been activated by atp an intracellular vesicle fuses with the plasma membrane and releases its contents to the extracellular fluid molecules move across the plasma membrane without an input of energy the plasma membrane folds inward to form a vesicle containing extracellular material molecules pass directly through the phospholipid bilayer of the plasma membrane

Explanation:

Active transport requires energy (ATP) to move molecules against their concentration gradient, often via transport proteins. The other options describe passive transport (no energy, like simple diffusion or facilitated diffusion without ATP) or vesicular transport (endocytosis/exocytosis), not primary active transport which directly uses ATP to power transport proteins.

Answer:

molecules move through transport proteins that have been activated by ATP
