Glycolysis and gluconeogenesis are irreversible processes and that both occur largely in the cytosol of animal cells, necessitatingtheir reciprocal and coordinated regulation. When I consider how cells reciprocally regulate these two pathways at the molecularlevel, I think...

Calculations based on the volume of a glucose residue and the branchingpattern of cellular glycogen indicate that a glycogen molecule could have up to 28 branching tiers before becoming impossibly dense. What are the advantages of such a molecule and why is it not found in vivo?
Both prokaryotic and eukaryotic organisms carry out some form of glycolysis. How does ha fact support or not support the assertion that glycolysis is one of the oldest metabolic pathways?
A glucose-fed yeast cell is moved from an aerobic environment to an anaerobic one. For the cell to continue to generate ATP at the same rate, approximately how much glucose must it consume in the anaerobic environment compared with the aerobic environment?
Describe in general terms the structural makeup of a mitochondrion.
How are the mitochondrion and the hydrogenosomesimilar structurally? How do they differ? How do theydiffer metabolically?
How many ATP will be produced in an oxidative level phosphorylation of a molecule of glucose in a eukaryotic cell?
Why does the Krebs cycle operate only under aerobic conditionseven though it does not use molecular oxygen in any of its reactions?
mitochondrion function in plants and animals
Cells can generate as many as 36 to 38 molecules of adenosine triphosphate (ATP) from the metabolism of one molecule of glucose. Which cellular process results in this amount of ATP production?
Consider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O? If all ten are first incorporated into glycogen, liberated from glycogen, and then fully catabolized into CO2 and H2O, does the ATP tally increase, decrease or stay the same? Consider that 1 UTP = 1 ATP. Explain. Describe the processes which produce ATP and provide a balanced equation of glucose, CO2, H2O and O2
List down the specific functions of the component structures of mitochondrion relative to cellular respiration.
When a vertebrate dies, its muscles stiffen as they are deprived of ATP, a state called rigor mortis. Using your knowledge of the catalytic cycle ofmyosin in muscle contraction, explain the molecular basis of the rigor state.
