Summarize the 4 phases of glucose breakdown

There are 4 phases of glucose breakdown. Summarize the major events (include inputs/outputs/location) of each.

Expert Solution

Glucose is a six-carbon sugar that can be ingested or infused directly into the body, but is more often a by-product of complex carbohydrate, protein or fat metabolism. Glucose can be used to synthesize glycogen and other storage fuels or broken down further to provide energy for metabolic processes, a series of reactions collectively termed cellular respiration. The stages of glucose breakdown can be divided into four distinct phases.

During glycolysis, glucose ultimately breaks down into pyruvate and energy and 2 ATP is made in the process. If there is no oxygen (Anaerobic condition), then fermentation takes place wich happens in the cytoplasm and only 2 ATP molecules are made. If there was oxygen (aerobic condition), The citric acid (kerb) cycle will take place which finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process by making 36 to 38 ATP molecules.

I understand that pyruvate is the result of the breakdown of glucose and is vital to the citric acid cycle and that oxaloacetate is a four-carbon molecule. I was hoping someone could differentiate the two in terms of their overall function and importance to cell processes. How does the cell know which one to use at which time??

Describe how glucose-6-phosphate formed by glycogen breakdown in the liver converts to glucose by glucose-6-phosphatase and how the newly formed glucose leaves the liver cells. Describe why this process allows for separation from glycolysis.

How does the breakdown of glucose fuel the electron transport chain?

Use bond enthalpies to estimate a) the enthalpy of the anaerobic breakdown of glucose to lactic acid in cells that are starved of oxygen, C6H12O6(aq) → 2 CH3CH(OH)COOH(aq), b) the enthalpy of combustion of glucose. Ignore the contributions of enthalpies of fusion and vaporization.

The metabolic breakdown of glucose produces CO2, which is expelled from the lungs as gas.

Place numerical answers to three significant digits in the blanks provided. The metabolic breakdown of glucose produces CO2, which is expelled from the lungs as gas. Calculate the volume of CO2 produced at body temperature when 5.00 g of glucose breaks down. Assume this occurs at 1.08 atm.

Summarize the material covered in today’s lab. Name and describe each of the phases of the cardiac cycle. Be sure to include the events that occur during each phase. Focus on the mechanical events (contraction and relaxation) of the chambers, the pressure changes in the heart, the position of the valves, and the heart sounds. Be sure to explain what causes each of the events you describe.

Compare how many ATP molecules can be maximally formed by the breakdown of a glucose molecule in a cell lacking mitochondria, a cell that has mitochondria with ion channels specific to protons in its inner membrane, and a cell that has normal mitochondria. Justifications for the calculations must be given and full accounts of the calculations must be provided so that the number of ATP molecules can be traced back to relevant reactions / processes.
