Step 1
Glucose to Glucose-6-phosphate: This step involves the addition of a phosphate group to glucose, using ATP as the phosphate source. So, this is a phosphorylation step. **Step 1** Show more…

Glycolysis is the first step in cellular respiration. This step-by-step process is run with the help of 10 different enzymes as glucose is modified and eventually changed into two molecules of pyruvate. ATP is used and produced along the way. An accumulation of ATP that is not used by the cell can alter this process by interfering with the third enzyme, thus temporarily shutting or slowing glycolysis down. As ATP is used up by the cell and drops to a lower level, the interference with the third enzyme ceases and glycolysis continues. Such regulation of this metabolic pathway is the result of: a. catalytic feedback b. positive feedback c. negative feedback d. bioinformatics regulation
