What is the test on appeal for determining if substantial evidence supports a conviction?

The test on appeal for determining if substantial evidence supports a conviction is whether " 'a reasonable trier of fact could have found the prosecution sustained its burden of proving the defendant guilty beyond a reasonable doubt.' " (People v. Johnson (1980) 26 Cal.3d 557, 576, 162 Cal.Rptr. 431, 606 P.2d 738.) In making this determination, we " 'must view the evidence in a light most favorable to respondent and presume in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence.' " (Ibid.)
