2. Why is water important for cell health? -helps transport items throughout the cell -helps keep cell shape and structure (creates pressure inside a cell) -water forms a large component of blood, and blood transports items through the organism -dissolves nutrients and minerals so they are more accessible -helps form proteins and DNA -important in photosynthesis for plants (photosynthesis is the process where plants make their own food) -required in cellular respiration -helps form cell membranes surrounding cells -involved in chemical reactions within cells -helps regulate temperature, helps create sweat, temperature regulation is important for proper function of cells -part of cytoplasm which move things throughout the cell (water is the universal solvent) 3. Why is oxygen important for cell health? -oxygen is important for cells because it is used in cellular respiration which helps a cell create energy to do everything it needs to do. - oxygen comes from the inhaled air (20% oxygen and 79% nitrogen) -oxygen enters lungs, diffuses through small air sacs into capillaries (small blood vessels) -protein called haemoglobin in red blood cells carries oxygen to various parts of the body -once the oxygen reaches the various body cells, the cell then uses oxygen to break down sugar molecules in a process called cellular respiration -the breakdown of sugar creates energy for your body to carry out its various functions -as a byproduct of the sugar breakdown, carbon dioxide is produced and energy is released (this energy is stored for the cell to use at a later point) -carbon dioxide is then transported through the blood to the lungs to be exhaled -cellular respiration is the reverse formula of photosynthesis
