Question

For every glucose molecule that is broken down via glycolysis, two 3-carbon (13) molecules are made along with the net production of (14) ATP and (15) NADH molecules. If oxygen is available, pyruvic acid is converted to (1 which combines with OAA to enter the (17) cycle. This cycle produces 18 ATP, three (19) and (20) FADH2 per 1 turn of the cycle. Each NADH can be converted to (21) ATP. The (22). of NADH and FADH2 are passed to the proteins that comprise the (23) system. They are then passed to (24) the final electron acceptor. As they are passed, they lose energy and this energy is used to pump (25 from one side of the (26) membrane to the other, which creates a gradient. The enzyme (27 harnesses the energy in the gradient to produce ATP. This mechanism of ATP production is known as the (28) hypothesis.
