Question

how many co2 are released per glucose molecule in the citric acid cycle? multiple choice 1 point 1 2 3 4 5

Explanation:

Step1: Recall citric - acid - cycle facts

In the citric - acid cycle, for each glucose molecule (which is split into two pyruvate molecules, and each pyruvate enters the citric - acid cycle after conversion to acetyl - CoA), a total of 6 CO₂ molecules are released. Each turn of the citric - acid cycle (per acetyl - CoA) releases 2 CO₂ molecules, and since one glucose gives 2 acetyl - CoA, 2×3 = 6 CO₂ are released in the citric - acid cycle from one glucose.

Answer:
