this substance together would release a certain amount of oxygen‚ this varied over the course of six minutes. We tested the yeast a total of four times using the gas sensor each time. The gas sensor would be left in the bottle for at least six minutes. The oxygen

d) In the lungs and tissue e) i) Deoxygenated blood has less oxygen than the alveolar air. ii) This causes oxygen to diffuse out of the alveolus into the blood capillaries. f) Oxygen molecules pass through and dissolve in the thin film of moisture in the alveolar wall. The oxygen then pass through the thin layer of alveolar epithelial cells and the endothelial cells of capillary wall. g) Oxygenated blood has more oxygen and less carbon dioxide than the tissue. 3. a) A – Water

Carbohydrates are made up of carbon‚ hydrogen‚ and oxygen. It provides energy for the body‚ especially the brain and the nervous system. The food sources are in sugar and grains. Lipids Lipids are made up of hydrogen‚ carbon and oxygen. It provides Energy storage‚ acting as structural components of cell membranes‚ and hormone production. The food sources are in fatty acids‚ dairy‚ and trygycerols. Proteins Proteins are made up of hydrogen‚ oxygen‚ nitrogen and carbon. It provides energy

aeneus is an organism that respires bimodally ‚ that it is being capable of drawing oxygen from both water and air. It carries out aerial respiration through it’s adapted posterior intestine.This experiment was done in order to determine the disadvantages of aerial respiration by manipulation of oxygen content and depth. The effect of dissolved oxygen‚ when the fish was placed into a cylinder of water and the oxygen concentration was determined while the number of breaths in a 10 minutes period was

Aerobic Treatment In the biological process‚ if the micro organisms (aerobes) use free or dissolved oxygen for the degradation of organic wastes‚ it is named as aerobic treatment. The availability of the oxygen for the working of aerobes as an electron acceptor accelerates the biodegradation significantly and maximized the treatment system capacity. Factors influence on treatment process The microorganisms and their growth are the driving force for the degradation process. To achieve a high rate

membrane through diffusion. Diffusion is the process of which the respiratory gases across the gas exchange membrane (oxygen from the environment into the body‚ carbon dioxide from the body to the environment). Using the concentration gradient along the gas exchange surface. For gas exchange to occur these three Features are needed; the gas exchange surface needs to be moist so that the oxygen and carbon dioxide can dissolve in water (H2O) in order to diffuse across the membrane. The gas exchange surface

equation for ATP(energy) is ATP-> energy+ adenosine diphosphate(ADP+P). there are two pathways anerboic and aerobic respiration. aerobic requires oxygen in order for respiration to take place. The equation for this is glucose + oxygen -> carbon dioxide + water(+energy). Anerboic respiration does not require oxygen it only happens when there is not enough oxygen for aerobic respiration. The equation for this is glucose -> lactic acid (+energy relesed). When a muscle contracts it creates movement which

transport of oxygen to the cells of tissues and organs by blood vessels is vital for respiration to occur. Oxygen is carried in red blood cells by the pigment haemoglobin‚ a globular protein consisting of four polypeptide chains. Both of these components of blood are structured specifically to carry out their functions of oxygen transport‚ hence ensuring efficient respiration. Erythrocytes‚ or red blood cells‚ possess a unique structure that enables them to play their role in oxygen transport. They

respiratory gases across a membrane. It is the delivery of oxygen to the body‚ and the elimination of carbon dioxide from the body .The reason why gas exchange takes place because oxygen is one of the most essential requirements of life‚ without which organisms on Earth would not survive. Living organisms generate energy from food through the process of respiration. This allows humans and other organisms to perform their daily tasks. Oxygen is used in mitochondria to generate adenosine triphosphate
