Which of the following is an incorrect match of process to location? (a) citric acid cycle - matrix of mitochondria(b) preparatory reaction - cristae of mitochondria(c) glycolysis - cytoplasm(d) atp production in the electron transport chain - cristae of mitochondria

(B) preparatory reaction - cristae of mitochondria

Explanation:

The oxidative decarboxylation of pyruvate into acetyl-CoA is also called preparatory reaction.  

Glycolysis occurs in cytoplasm and forms two molecules of pyruvate from one molecule of glucose. The transport proteins transport pyruvate from cytoplasm to the matrix of mitochondria.  

Pyruvate dehydrogenase enzyme complex is present in mitochondria which carry out oxidative decarboxylation of pyruvate and forms one molecule of acetyl CoA from each pyruvate molecule.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
