REDUCTION Oxygen makes up only about 20% of the air‚ yet is the essential component for so many reactions. Without it fuels would not burn‚ iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where oxygen is added

Biology practical 10 Photosynthesis January‚ the 28th‚ 2013 Done by: Instructor: Introduction Respiration is the number of processes which leads to the oxidation of organic compounds to produce the energy. There are several types of respiration‚ and one of them is aerobic. During the aerobic respiration‚ human uses the oxygen from atmosphere and produce carbon dioxide. A cardiorespiratory system which includes lungs‚ heart‚ blood vessels and others is responsible for all the processes

1. The Oxygen Cycle 2. What is oxygen? a. Oxygen is an element b. Colorless‚ odorless and tasteless gas c. Denser than air d. very poor conductor of heat and electricity 3. Picture. 4. Oxygen Cycle a. Step one i. Plants release oxygen into the atmosphere as a by-product of photosynthesis b. Photosynthesis c. Definition- The process in which green plants use the energy from the sun to make carbohydrates from carbon dioxide and water in the presence of chlorophyll 5. Steps to the photonthesis

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems‚ etc. The parts of a typical leaf

for finding some advice. On this exhibition we learned that the plastic could recycle to different kind of valuable thinks. Such as T-shirt‚ Cups‚ Pens etc.… … However‚ we also go to Tuen Mun Yan Oi Tong Recycle Centre. We are attending a lesson on the centre. Their member who is repents the recycle schemes about the plastics. Also‚ base on their statistics of recycle rate‚ housing estates is a top in 1 of 4 recycle rate of the collection method. The reason of why housing estate is the most

effect of differing wavelengths of visible light on the photosynthetic activity of Beta vulgaris Introduction Photosynthesis is a crucial biological process that occurs within the chloroplasts of plant cells where CO2 + H2O + Sunlight C6H12O6 + O2. The chloroplasts use light‚ an electromagnetic energy source‚ to produce food for the plant in the form of sugar molecules. During photosynthesis‚ the excited electrons from the light pass through proteins in the electron transport chain (ETC)‚ where ATP

DECISIONS SERIES Oxygen Saturation A Guide to Laboratory Assessment BY SHANNON HAYMOND‚ PHD uman life depends on the oxygen transport by hemoglobin. In healthy patients‚ the majority of molecular oxygen (O2) is bound to hemoglobin and only a small fraction is dissolved in blood. But in patients with respiratory problems or certain metabolic and genetic disorders‚ the fraction of oxygenated hemoglobin can fall to dangerously low values. Therefore‚ laboratory assessment of oxygen saturation (SO2)—the

Introduction Photosynthesis is the process by which autotrophic organisms convert light energy to chemical energy in the form of glucose. Without this process life on earth would be very different because every organism directly or indirectly depends on photosynthesis. Photosynthesis helps the plants to grow roots‚ leaves‚ flowers and fruits. It is an extremely important process because plant tissue serves as the bottom of every food chain. The process of photosynthesis is dictated by a number
