Question

if this was a yeast cell instead of a human cell and oxygen was not present. how much ATP would be gene if this was a yeast cell instead of a human cell and oxygen was not present. how much ATP would be gene if this was a yeast cell instead of a human cell and oxygen was not present. how much ATP would be gene if this was a yeast cell instead of a human cell and oxygen was not present. how much ATP would be gene if this was a yeast cell instead of a human cell and oxygen was not present. how much ATP would be gene ulgcussed in class. These checkpoints can pause the cell cycle dell cycle is controlled at three major checkpoints that conditions are unfavorable. The first checkpoint occurs when the ce G1 and entering S phase. Before the cell can enter if the environment is favorable to progress to S pha condition in the environment would prevent a cell form progressing phase? Only one answer. (3points) if ll is leaving S phase the cell determines se. What unfavorable to s 9. In question 8 above 1 described where the first checkpoint occurs in the cell cycle. Describe the other two checkpoints in the cell cycle. (10 points) Checkpoint 2 regulates entry into What are the two requirements for the cell to progress past checkpoint 27 The cell progressos past checkpoint 3 if all are attached to ofore they are segregated to opposite poles of the cell.

Explanation / Answer

In yeast cell mainly 2 ATP generated. During fermentation process due to anaerobic condition (no presence of oxygen) all NADH produced during glycolysis is consumed so there is no net NADH production and no NADH to enter ETC (electron transport chain) cycle to form more ATP whereas in aerobic condition one glucose undergoing glycolysis produces upto 38 ATPs.
