The movement of substances from lower to higher concentration across a semi permeable membrane that must have a specific protein carrier and cell expenditure of energy is called

Question

Quizplus · Accepted Answer

The description matches the process of active transport, which involves the movement of substances against their concentration gradient with the use of energy and specific protein carriers. Facilitated diffusion also involves the use of protein carriers but does not require energy expenditure, while diffusion and osmosis do not involve protein carriers or require energy expenditure. Endocytosis is a process of cell ingestion and is not relevant to the given description.
