Cellular respiration is a process by which the simple sugar glucose is oxidized (combined with oxygen) to form the energy-rich compound adenosine triphosphate (ATP). Respiration requires enzymes to catalyze the oxidative breakdown of glucose, the respiratory substrate for respiration. At the current rate of global energy demands, fossil fuels cannot replenish fast enough to meet these growing needs. But photons of different wavelength have different energy content, according to the Planck's law. This is known as the Q10. 3) As temperature increases up to a certain point germination/respiration will increase. Hypothesis is included. ATP powers all cellular activities. The temperature altered the crickets' cellular activity and thus, effected their cellular rates of respiration. During cellular respiration, the chemical energy in the glucose molecule is converted into a form that the plant can use for growth and reproduction. Amthor (1991) described two different effects of [CO 2] on plant respiration rates that can be distinguished experimentally: a direct effect, in which the rate of respiration of mitochondria or tissues could be rapidly and reversibly reduced following a rapid increase in [CO 2] (Amthor et al.
