Detailed explanation-1: -Three transport processes that do not require energy are; diffusion, osmosis and facilitated diffusion. Facilitated diffusion is a passive process: the solutes move down their concentration gradient and do not require the expenditure of cellular energy for this process.
Detailed explanation-2: -1 Lipid diffusion (simple diffusion) Passive transport requires no energy input, as compounds are able to move freely across the membrane based only on a favourable concentration gradient (Figure 1.11).
Detailed explanation-3: -Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane.
Detailed explanation-4: -Not everything enters the cell through passive transport. Only the smallest molecules like water, carbon dioxide, and oxygen can freely diffuse across cell membranes. Larger molecules or charged molecules often require an input of energy to be transported into the cell.
Detailed explanation-5: -The two types of passive transport are : Simple diffusion and facilitated diffusion .
