The statement that is NOT true about one molecule of glucose in cellular respiration is: "produces many NADPH as electron carriers".

Here's why:

1. "Produces 36 ATP after three steps are completed" - This is true. The three steps of cellular respiration (glycolysis, Krebs cycle, and electron transport chain) can produce up to 36 ATP molecules from one glucose molecule.

2. "Requires that the Kreb Cycle be done twice" - This is also true. One glucose molecule is broken down into two pyruvate molecules during glycolysis, and each pyruvate goes through the Krebs cycle.

3. "Produces many NADPH as electron carriers" - This is NOT true. While glucose metabolism does produce electron carriers, they are NADH and FADH2, not NADPH. NADPH is produced in photosynthesis, not cellular respiration.

4. "Was created from the breakdown of carbohydrates in digestion" - This is true. Glucose is a simple sugar that is created from the breakdown of more complex carbohydrates during digestion.

5. "All of the above" - Since one of the statements is false, this choice is also false.
