maximum rate of photosynthesis. What value of light intensity produced photosynthetic saturation in corn leaves? Photosynthesis first must be determined by plotting O2 evolution vs time at different light levels. The rates calculated from each O2 evolution curve are then plotted against light level. [ For example‚ the figure below shows O2 evolution curves when photosynthesis was allowed to occur in the presence of two different light

16. Using the following SKELETON equation: NH3 + O2 NO2 + H2O a) Balance the above equation … what is the molecule ratio? b) What is the ratio of moles of Oxygen used to moles of NO2 produced? c) How many molecules of H2O are produced when 18.3 moles of NH3 are used (assume excess O2)? 17. Draw a particle picture to represent the equation in #16 (above) when given 4 molecules of NH3 and 8 molecules of O2 react to form NO2 and H2O

Thermoregulation is the “maintenance of a steady body temperature even under a variety of external conditions” Harvard. Based on the process of thermoregulation‚ animals are divided into two groups‚ ectoderms and endotherms. Ectoderms are animals that are poor thermoregulators‚ having their body temperature determined by the ambient temperature. Animals that fall into this category are reptiles‚ amphibians‚ and fish. On the other hand‚ endotherms are animals that can thermoregulate and keep their

fate of pyruvate‚ however‚ is somewhat different between cancer and non-cancer cells. Normal cells will generally use pyruvate for aerobic respiration in the Tricarboxylic Acid (TCA) cycle and oxidative phosphorylation if oxygen (O2) is present. In the absence of O2‚ these cells will undergo anaerobic respiration and convert pyruvate into lactic acid. Cancer cells‚ on the other hand‚ will push pyruvate through the anaerobic pathway regardless of O21‚ 2. While this metabolic pathway yields less

Is Ireland’s current women’s prison system fit for purpose? 1500w Throughout this essay the author aims to examine the prison system in Ireland‚ in particular the author will focus on the impact of the system on female inmates. A thorough exploration of the women’s prison system will be undertaken in order to establish the level to which this system is fit for purpose. The author intends to critically assess the system and its implications on women and wider society. The author will evaluate the

Oxygen (O2) is released by the plants as bi-product into the atmosphere. * Respiration Just as plants carry out photosynthesis‚ animals carry out respiration. Respiration occurs when animals take in oxygen from the air along with simple sugars from their food. This helps in release of carbon dioxide‚ water and energy from the animal body. During cellular respiration‚ animals require O2 during inhalation. When they exhale the
