Active and Passive Transport | Back to Top. Passive transport requires no energy from the cell. Examples include the diffusion of oxygen and carbon dioxide, osmosis of water, and facilitated diffusion. Types of passive transport.
Energy is required for cells to perform many functions. Enzymes convert substrates into products but must do so against the activation energy (so energy is needed here). Cellular respiration requires some amount of energy to occur. The most important energy consumer is the Na+/K+ ATPase ion pump which is responsible for maintaining cellular gradients and consumes approximately 50% of the energy of the cell.
