Q- Which molecules help in active transport through plasma membrane? Answer- The Carrier molecules which are also called permeases or pumps helps in active transport through plasma membrane.
Q- Name two processes involved in passive transport of biomolecules. Answer- The two main processes which are involved in passive transport of biomolecules are: 1. Diffusion 2. Osmosis
Q- State one difference between diffusion and osmosis? Answer- Osmosis is the flow of water or any other solvent from a region of higher water concentration to a region of region of lower water concentration through a semipermeable membrane while Diffusion involves the movement of substances from higher concentration to lower concentration due to diffusion.
