Within a cell, the complete breakdown of glucose to generate ATP occurs by two fundamentally different mechanisms.  Name and briefly describe these mechanisms.

List two means by which enzyme activity is directly regulated.

Glycolysis is an important pathway for energy production. As such, the enzymes are always present. After eating a meal, blood glucose levels rise drastically, requiring a rapid increase in glycolytic enzyme concentration to metabolize the influx of glucose. When the blood glucose level drops to baseline, the concentration of glycolytic enzymes is reduced in the cell. Question :- Describe one pathway that allows the cell to rapidly increase glycolytic enzyme levels and one pathway that can be used to reduce glycolytic enzyme levels.

Glucose is degraded into glucose and oxygen is released by respiration in Cows. From where, this glucose comes in Cows? Explain in detail each step of Glycolysis in your own words. Do not draw the Diagram. List enzymes and ATP used and synthesized. Where Glycolysis occurs in cells?

In each of two steps during the "Energy payoff stage" of glycolysis, ATP is generated when an enzyme uses one of the phosphate groups attached to one of the ends of a 3-carbon intermediate molecule to phosphorylate (add a phosphate group) ADP, forming ATP.  This mechanism of producing ATP from ADP and a phosphate group is known as:   Question 9 options:   substrate level phosphorylation   redox phosphorylation   lactic acid fermentation   oxidative phosphorylation

(b) Metabolic state of cells and organism can be associated with inmplication of ATP and NADH. Explain this relationship.

explain the role adenosine tri phosphate (ATP) and adenosine di phosphate (ADP),  play in producing anaerobic and aerobic energy within the body. Identify how much ATP is produced following anaerobic and aerobic metabolism.

Which of the following conditions will produce active glycogen phosphorylase? AMP АТР Phosphorylation of Serine 14 Glucose Glucose-6-Phosphate Phosphorylation of Serine 14 and AMP Phosphorylation of Serine 14 and ATP

Define the thermodynamic term “work.” Provide two physiological examples of work.

After infection, some T cells (a particular type of immune cell) may persist as memory T cells (TMcells). When they re-encounter the same pathogen, T­M­ cells rapidly divide to produce more T cells to help fight off the infection. This rapid cell division requires substantial energy. One way that this energy is provided to TMcells is via increased activity of the ETC. One standard type of experiment for analyzing oxidative metabolism is measuring the oxygen consumption rate OCR in the presence of different compounds. The lines indicate the time at which the different ETC/OxPhos inhibitors were added. Note that the inhibitors are never removed. Complete the table below. Time Period 1 2 3 4 Inhibitor added None Oligomycin (inhibits ATP Synthase) FCCP (Uncoupler) Rotenone + Antimycin (Complexes I and III) Can electrons flow? If so, from which compound to which compound? If not, what is preventing it?         Can H+move through the membrane? If so,…
