Glycolysis is a series of enzymatic reactions that break down glucose molecules into two three-carbon molecules called pyruvates. This series of reactions is an important part of cellular respiration, and it helps to create energy for cells.
Statement #1: No Oxygen Is Used in This Process
This statement is true. Glycolysis occurs in the cytoplasm of cells, so oxygen is not required for this process.
Statement #2: Glycolysis Does Not Occur in Yeast
This statement is false. Yeast, as well as many other organisms such as bacteria, plants, and animals, can use glycolysis to generate energy.
Statement #3: No ATP Is Formed
This statement is false. Glycolysis results in the formation of two molecules of ATP, as well as two molecules of pyruvate.
Statement #4: Phosphorylation Halts the Process When ATP Levels Get Too Low
This statement is true. During glycolysis, ATP levels are monitored to ensure the process can continue. If ATP levels drop too low, phosphorylation will halt the process.
