How to arrive at the estimate that each glucose molecule theoretically yields 36 ATPs. Concept introduction: The cellular respiration involves the breakdown of glucose molecules in the presence of oxygen to release water, carbon dioxide and ATP. It is an aerobic and multistep process that involves glycolysis, Krebs cycle and electron transport system.

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

For each of the four possibilities listed below (a through d), only one answer is correct and the others are false. Identify the correct statement and explain why the others are false. In your answer, write CORRECT next to the statement that you think is true, and ONLY for the ones that you think are false, explain what is wrong with the statement . When glucose reacts with ATP to form glucose-6-phosphate (as shown on the figure below): 1. The synthesis of glucose-6-phosphate is exergonic 2. ADP is at a higher energy level than ATP 3. Glucose-6-phosphate is at a higher energy level than glucose 4. Because ATP donates a phosphate to glucose, this is not a coupled reaction

In biological systems, enzymes are used to accelerate the rates of certain bio- logical reactions. Glucoamylase is an enzyme that aids in the conversion of starch to glucose (a sugar that cells use for energy). Experiments show that 1 pg mol of glucoamylase in a 4% starch solution results in a production rate of glucose of 0.6 ug mol/(mL)(min). Determine the production rate of glucose for this system in the units of Ib mol/(ft³)(day). Ibmol Answer: 0.0639 ft day True False

The conversion of glucose to glucose 6-phosphate is an endergonic reaction (eql below). The second equation below is an exergonic reaction that can occur in all cells. Considering this information, how can the reaction in equation 3 proceed? EQ1: Glucose + Pj --> glucose 6-phosphate EQ2: ATP + H20 --> ADP + Pj EQ3: Glucose + ATP --> glucose 6-phosphate + ADP Select one: a. The energy required to make Eq3 spontaneous is provided by the enzyme catalyzing the reaction b. The energy released from equation 1 is more than the energy consumed in equation 2 making the overall reaction AG negative and the reaction spontaneous. c. The energy released from equation 2 is more than the energy consumed in equation 1 making the overall reaction AG positive and the reaction spontaneous. d. The energy released from equation 2 is more than the energy consumed in equation 1 making the overall reaction AG negative and the reaction spontaneous. e. The energy released from equation 1 is more than the energy…
