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

muscles contract and relax. Muscles normally work in pairs first one contracts (become shorter and wider) and the other relaxes (becomes longer and thinner) this is how they work when moving bones. (1) Formula for aerobic respiration Glucose + oxygen Carbon Dioxide + water (+ energy) Muscle fatigue and what causes it Muscle Fatigue is when a muscle gets tired and does not have the ability to generate a force. It can occur because of too much vigorous exercise (aerobic respiration)

The experiment we conducted in lab used three different species of algae‚ Macrocystis (brown)‚ Plocamium (red) and Ulva (green). Before we conducted anything‚ we first measured the initial oxygen concentration in the water that was used to house each alga. This was done because in the water that we used there happened to be phytoplankton which can respire and photosynthesize. If we didn’t take them into consideration our results would end up skewed. Once that was known we took a piece of each algae

and several raw materials such as carbon dioxide and water to produce sugars and release oxygen into the atmosphere. It does not only supplies oxygen which required for human life but it is also the primary source of food energy for all forms of life‚ directly or indirectly. Cellular respiration is the process of converting food molecules such as glucose into energy in the form of ATP. In this process‚ oxygen is utilized and carbon dioxide is produced. Carbon dioxide‚ required for photosynthesis by

the survival of an organism. The purpose of this process is to obtain oxygen from the environment (which is necessary for cellular respiration‚ and to dispose of CO2‚ a bi product of respiration. An efficient gas exchange system has 3 requirements. It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first dissolve into a fluid before it can diffuse into a cell. Having

respiratory system role with oxygen and carbon dioxide. The respiratory system is responsible for the movement of gases involved in cellular metabolism. b. Why is oxygen needed? Oxygen is needed because it is used up during the aerobic breakdown of glucose. c. What generates CO2? Carbon dioxide arises from the aerobic metabolism of glucose . 2. Define the three important continuous physiological processes that are responsible for the movement of oxygen and carbon dioxide. Ventilation
