amount is oxygen‚ that’s where VO2max comes into play. VO2max is “the volume of oxygen a person can consume in one minute as he or she exercises at maximum exertion” (paragraph 4). With Team NOVA‚ their VO2max levels were measured before and after their nine months of training; and they were dramatically better after. It’s not the VO2max levels that help with receiving enough oxygen when running‚ it is merely an indicator. The amount of red blood cells present in your body help with your oxygen intake

Ozone As A Disinfectant Joey Finnegan Section 01 October 3‚ 2010 Ozone is a highly reactive gas composed of three oxygen atoms. Ozone is an unstable gas that can destroy bacteria and viruses. Ozone can have many different effects on humans depending on where it is in the atmosphere‚. Some of these effects can be harmful although some can be good. An excess‚ or high concentration of ozone in an inclosed area can be quite harmful to humans although in moderation and if used properly ozone

conversion of light energy to chemical energy took place in the chloroplast. In 1881‚ he observed the movement of bacteria towards the chloroplasts in a strand of “Spirogyra” algae. Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photo synthetically active chloroplasts in the algae. This was one of the first documented observations of positive aero taxis in bacteria. In 1882‚ he performed his famous action spectrum experiment using a device designed and built

Biology Notes 1.02 Sometimes a practice or belief claims to be science but does not follow the scientific method or cannot be proven reliable through experimentation. These practices are examples of pseudoscience‚ which literally means "fake science." Charms‚ astrology = stars‚ and phrenology= reading the bump on skull 1.03 * In the mid 1600s in the Netherlands‚ the scientist Antonie van Leeuwenhoek developed the first known microscope using a single magnifying lens. He was the first person

Research Question Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating

reacts within cells. Cellular respiration is the process by which cells break down sugars (ATP) in order to produce energy for other chemical reactions. Cellular respiration takes place mainly in the mitochondria and the reactants in this process are oxygen and glucose and the main product in this process is ATP as well as waste products which include carbon dioxide and water. Almost all organisms perform cellular respiration. There are two types of cellular respiration

be aerobic respiration or anaerobic respiration. During the process‚ prokaryotic cells carry out cellular respiration within the cytoplasm‚ or‚ in the inner surfaces of the cells. In cellular respiration‚ the reactants are oxygen and glucose. When an organism breathes‚ oxygen enters into its body. When an organism eats and consumes‚ glucose enters the body. The output of cellular respiration is carbon dioxide and water. During the process‚ carbon dioxide is being taken from the mitochondria out of

Structure of Gaseous Exchange Surfaces in Humans‚ Fish‚ Insects and Frogs Gaseous Exchange is a biological process where oxygen diffuses into the body or bloodstream and carbon dioxide diffuses out of the body or blood stream. This process is different for Humans‚ Fish. Frogs and Insects. Humans: In humans the gas exchange system is known as the Respiratory system. The respiratory surface is the Alveoli located on Bronchial tubes inside of the lungs. The average human adult has about 600 million

What is the role of the electron transport system? Include the reactants and the products. Where does it occur? The electron transport system is the final stage in cell respiration. The main role is to transport electrons formed from NADH to oxygen in order to release the energy cells use to make ATP. Photosynthesis:
