The enzyme ATP synthase is embedded in the mitochondrial cristae. Which specific part of this enzyme complex protrudes into the matrix and catalyzes ATP formation?
Q1. The enzyme ATP synthase is embedded in the mitochondrial cristae. Which specific part of this enzyme complex protrudes into the matrix and catalyzes ATP formation?
Answer: F1 particle
Explanation: The F1 particle (headpiece) contains the catalytic site for ATP synthesis; the Fo part acts as the proton channel through the membrane.
