Active and passive transport are biological processes that move oxygen‚ water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand‚ passive trasport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.

TASK 3 COMPONENTS OF BLOOD AND TRANSPORT OF OXYGEN Blood components are red cells‚ white cells‚ platelets and plasma. These can be put to different uses. RED BLOOD CELLS Red blood cell also known as erythrocytes make up 45% of blood volume lacks nucleus and contains the oxygen-carrying protein haemoglobin‚ which is a pigment that gives whole blood its red colour. Erythrocytes are produced inside of red bone marrow. Its main function is to distribute oxygen to body tissue‚ and carry waste

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

Active and passive transport are the ways in which cells allow things to move into and out of the cell through the cell membrane. They include many different ways to transport things. Passive transport requires no expenditure of energy by the cell. However‚ Active transport requires ATPs which have energy in order for it to move something through the cell membrane. There are different types of transport to suit the sizes of molecules as well. Passive transport includes diffusion‚ osmosis‚ and
