Two ATP molecules are gained in this stage. The transition stage takes place in the mitochondria. The pyruvate is combined with NAD+ to form NADH and acetyl coenzyme A molecules. In citric acid cycle stage the hydrogen atoms are removed from the acetyl coenzyme A molecules to use the electrons to create ATP. Eventually, all that is left of the acetyl coenzyme A molecules is carbon, which combines with the oxygen to from carbon dioxide that is emitted as a waste product.
Which of the following statements is correct concerning biotin. A. Intestinal biotinyl carboxylase cleaves biotin from biotin-containing proteins B. Biotinidase cleaves biocytin to yield biotin C. The first step in the intestinal digestion of biotin –containing proteins is the oxidation of the valeric side chain D. A and B E. B and C 8. Identify
Diagrams of Lock and Key Model A3b. Diagram of Activation Energy A4. Substrate The substrate of Aldolase B is fructose-1-phosphate. This comes from the breakdown of fructose by the use of fructokinase. Aldolase B is then converted into 2 products, DHAP and glyceraldehyde.
What is the concentration of glucose in ppm in a 0.00025 M glucose solution? The density of this solution is 1.02 g/ml. [pic] [pic] [pic] [pic] 5. Draw reaction diagrams for endothermic and exothermic reactions. Label each axis, reactants, products, heat of reaction (ΔH), and energy of activation (Ea).
Electrons can now continue to move through PSII and the cytochrome b6 f complex, and oxygen is produced in the water-splitting reaction. 34. Bioenergetics of Photophosphorylation The steady-state concentrations of ATP, ADP, and Pi in isolated spinach chloroplasts under full illumination at pH 7.0 are 120.0, 6.0, and 700.0 mM, respectively. (a) What is the free-energy requirement for the synthesis of 1 mol of ATP under these conditions? (b) The energy for ATP synthesis is furnished by light-induced electron transfer in the chloroplasts.
Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? The energy in fuel is converted into ATP, most ATP is made within the mitochondria. ATP powers the cells within muscles. • What is the role of glycolysis? Include the reactants and the products.
1. A solution containing 1.000M acetic acid (CH3COOH) and 1.000M ethyl alcohol (CH3CH2OH) at 150oC produced 0.171 mole/liter of the product ethyl acetate (CH3COOCH2CH3) when equilibrium was established. Determine Kc for the reaction. CH3COOH (aq) + CH3CH2OH (aq) CH3COOCH2CH3 (aq) + H2O (l) 2. Using the equilibrium constant from above, calculate the equilibrium concentrations of all the compounds in the reaction if 1.000M acetic acid is reacted with 2.000M ethyl alcohol.
