Investigating the Effect of Concentration on the Rate of Enzyme Catalysed Reaction To investigate the effect of concentration on the rate of enzyme catalysed reaction I must know all the factors that affect it in order to investigate in this. Here are all the factors: Temperature- Enzyme like it warm but not too hot. Enzymes are biological catalysts‚ which speed up chemical reactions. They work most efficiently at the optimum point (37°C). If they are below 37°C they will work

using strong stretching and contracting muscles this is how it moves. It has other important functions such as how it in gets it oxygen this is how‚ the earthworms respire through their skin‚ and therefore require humid conditions to prevent drying out. They coat themselves in mucus to allow the passage of dissolved oxygen into their bloodstream. The earth transports oxygen and carbon dioxide through the earthworm’s skin by diffusion. For diffusion to occur‚ the earthworm’s skin must be kept moist or

and another Cyril West were appointed to study ways to improve fruit storage. Applying information obtained while studying seed germination‚ Kidd and West demonstrated that fruit ripening could be retarded by increasing carbon dioxide and lowering oxygen in the storage atmosphere. And‚ from that day onwards and still ongoing‚ constant efforts are being made to control the atmosphere surrounding commodities and fruit‚ to help improve business logistics and better serve the customer.

interferes with cellular respiration. If inhaled‚ Hydrogen Sulphide combines with haemoglobin in the bodies of human beings and other mammals. haemoglobin is the substance in blood which carries oxygen to tissues. In combining with the haemoglobin‚ hydrogen sulphide prevents the transportation of oxygen. Without oxygen‚ people cannot live. Although hydrogen sulphide is very foul smelling‚ it can quickly paralyse the sense of smell‚ overcome the victim‚ and cause death.It also causes irritation of mucous

technique to access the internal body. One type of nanorobot which can be used is the respirocytes.The respirocytes are artificial mechanical red blood cells designed by Robert.A.Fretias. It is a 1000 atm diamondoid pressure vessel designed to deliver oxygen about 236 times more than the natural blood cells per unit cell volume. These respirocytes are provided with mechanical‚ chemical and pressure sensors and are implanted with an onboard microcomputer. The processor can be remotely controlled by the

could exert its toxicity through intracellular generation of reactive oxygen species (ROS). Tellurite inhibits the cellular response to oxidative stresses. To inhibit the growth of most normal bacterial inhabitants of the upper respiratory tract‚ including most species of Streptococcus and Staphylococcus‚ is to inhibit the growth of aerobic organisms through the presence of oxygen and high concentration of tellurite. Reactive oxygen species compounds such as hydrogen peroxide (H2O2)‚ superoxide anion

carbon dioxide and water causing the release of sugar and oxygen. Oxygen is also produced in photosynthesis‚ plants don’t really need oxygen so they give it out as a waste product but saves a little bit to use for respiration. The sunlight is absorbed by a green pigment called chlorophyll. Most of the glucose is turned into a substance called starch. Word equation for photosynthesis: Light energy Carbon dioxide + Water Glucose + Oxygen Chlorophyll Word equation for photosynthesis: Light energy

compounds as food and release of oxygen compounds as waste. The methods to measure the rate of photosynthesis are various. One method utilizes CO2 sensors to measure photoautotrophs CO2 intake under various luminescent environments. An elementary method utilizes H2O and NaHCO3 (Sodium Bicarbonate) for submersion of deoxygenized photoautotroph specimens to measure the release rate of oxygen compounds. Through the submersion method we recorded the rate of oxygen diffusion into the environment by

The initial research of sports science was to ensure energy levels and oxygen consumption to decrease fatigue and risks of injury (Hendricks). Latest in sports technology includes the RespiBelt.

Carbon Monoxide One of the main functions of the respiratory system is to provide the body with oxygen so that it can be delivered to vital cells that require oxygen to function.
