nervous system‚ muscle tone in the stomach and intestinal tract‚ and healthy skin‚ hair‚ and eyes The 20-2500 mitochondria per cell produce the majority of the body’s energy (ATP) by means of an intricate and complex process called cellular respiration. The production of ATP within the mitochondria involves two metabolic cycles called the "Krebs" or "citric acid" cycle‚ and the oxidative phosphorylation electron transport chain. Vitamin B1(thiamine) is a coenzyme used in removing CO2 from various

tolerance‚ microorganisms can be placed into four classes. Strict aerobes cannot survive in the absence of oxygen and produce energy only by oxidative phosphorylation.Strict anaerobes‚ in many cases‚ generate energy by fermentation or by anaerobic respiration and are killed in the presence of oxygen Aerotolerant anaerobes generate ATP only by fermentation‚ but have mechanisms to protect themselves from oxygen. Faculatative anaerobes prefer to grow in the presence of oxygen‚ using oxidative phosphorylation

This would mean that reproduction of a new cell would not occur and the whole process would not be possible. Part 2: Photosynthesis and Cellular Respiration Matrix Complete the matrix.

science in which all the other sciences are based. In biology you learn about living organisms and their composition. Organisms are alive because of chemistry - Why we breathe oxygen‚ how we make energy‚ elimination of waste products‚ cellular respiration‚ etc. All of these are based on how living organisms use chemistry to live. Biological organisms have chemical compositions. Carbon is found in all living organisms. After that‚ because there are many chemical processes occuring in various living
