The Krebs cycle occurs in the mitochondria. There are nine biochemical reactions involved in the Krebs cycle and they are highly ordered. Select the correct order from the following choices. Note these are abbreviated and do not show NAD, ADP, ATP, FAD, or water.
Acetyl - CoA joins the Krebs cycle and unites with oxaloacetate forming citrate which forms isocitrate which forms alpha-ketoglutarate which forms succinyl - CoA which forms succinate which forms fumarate which forms malate which forms oxaloacetate

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
