Question

question 9 of 10
which of the following produces nadh, atp, and two pyruvate molecules?
a. krebs cycle
b. calvin cycle
c. glycolysis
d. electron transport chain

Explanation:

Glycolysis is the metabolic pathway that breaks down one glucose molecule into two pyruvate molecules. During this process, \(2\) ATP (net gain, as \(2\) ATP are initially used and \(4\) are produced) and \(2\) NADH are generated. The Krebs cycle (citric - acid cycle) takes pyruvate derivatives (acetyl - CoA) as input. The Calvin cycle is part of photosynthesis (carbon - fixation cycle) and uses ATP and NADPH (not producing NADH in the way described). The electron - transport chain primarily produces ATP through oxidative phosphorylation using NADH and FADH₂ as electron donors.

Answer:

C. Glycolysis
