Question

1. Fill in the blanks, Glycolysis is taking place almost all organisms and almost all the cells. At rest, some tissues prefer fat as their energy source. For example, at rest, skeletal muscles is prefer fat as the energy source. However, energy provided by glucose metabolism is the sole source of energy for and Glycolyitc pathway is in this part of the cell: 2. Write overall reaction in glycolysis 3. Glycolysis has 10 steps. Why is 1" half called investing and second half as pay off steps? How many ATPs are used in the first half, how many ATPs are made in the second half? 4. Identify the redox step. You can write the step number. 5. What are the irreversible steps? Why are they irreversible?
