Pyruvate derived from glycolysis is transported into which structure to continue the process of cellular respiration?
A) mitochondrial matrix
B) mitochondrial cristae
C) cytosol
D) nucleus
E) lysosome

Question

Quizplus · Accepted Answer

Pyruvate is transported from the cytosol into the mitochondrial matrix, where it is oxidized to acetyl-CoA in the presence of oxygen to continue the process of cellular respiration. This process occurs during the second stage of respiration, known as the Krebs cycle or citric acid cycle, in which acetyl-CoA is further processed into ATP. Therefore, A) mitochondrial matrix is the correct answer as pyruvate enters this structure to continue the process of cellular respiration.
