thermodynamic quantity such as ΔH that is associated with a thermochemical equation always refers to the number of moles of substances explicitly shown in the equation. Thus for the synthesis of water we can write 2 H2(g) + O2(g)→ 2 H2O(l) ΔH = –572 kJ or H2(g) + ½ O2(g)→ H2O(l) ΔH = –286 kJ • Thermochemical equations for reactions taking place in solution must also http://www.chem1.com/acad/webtext/energetics/CE-4.html 1/11 4/6/2014 Thermochemistry and calorimetry specify

During carboxylation CO2 is fixed and raised temperature enhancing oxygenation. c.) Level of PGA depends on Rubisco with who is going to bind. Rubisco is an enzyme that reacts with CO2 and O2. The reaction with O2 competes with carboxylation reaction where CO2 is fixed. That means‚ if Rubisco catalyses with O2‚ the oxygenase wins‚ if there is enough CO2 in atmosphere‚ like at the beginning of evolution then it is the carboxylation reaction. d.) Increased oxygenase and reduced carboxylate activity

Ross (2002) claims that an effective e-supply chain strategy to be implemented require that trading channel partners begin defining the objectives to be pursued by each individual channel node as well as the entire supply chain acting as a unified market satisfying force. It means that Tables & Chairs Company and component suppliers will focus on the same goals and will be mutually supportive.

the ratio of CO2 molecules lost per O2 molecules consumed which can be used to determine the efficiency of the metabolic rate and can be calculated as follows; The R.Q can also help in determining the type of diet an organism is on. For example‚ a diet high in fat would result in a low R.Q due to the greater amount of O2 molecules required to metabolize that fat for ATP. On the contrary‚ a high protein diet would result in a larger R.Q due to a fewer amount of O2 molecules required to metabolize that

pick up O2 2. smooth muscle cells in walls of bronchioles are sensitive to PCO2 -increased PCO2 causes bronchiodilation -air flow directed toward lobules where PCO2 is high and CO2 is decreased (CO2 is bad) -these lobules contain CO2 obtained from blood (decreased PCO2 causes bronchioconstriction) Local controls – respiratory and cardiovascular systems -scenario: cells in interstitum are very active‚ so O2 is being used and PO2 decreases CO2 is being produces (PCO2 increases) -O2 is good
