The electrons formed from the aerobic oxidation of glucose are

i. ultimately transferred to o 2 after several other transfer reactions
ii. transferred to the coenzymes nad+ and fad
iii. directly transferred to o 2 during the citric acid cycle
iv. transferred to succinate and arachidonic acid

I. Ultimately transferred to O2 after several other transfer reactions

Explanation:

Electrons form glucose oxidation are first taken out  from glucose in glycolysis, by NAD+, that is reduced to NADH.

Also NADH is produced when pyruvate (glycolysis product) is decarboxylated and oxidized to acetyl-coenzyme A, previous to enter the Krebs cycle.

In the Krebs cycle, electrons form oxidation of citric acid first, and alpha keto-glutarate later are taken by NAD+, and stored as NADH. Steps later also FAD accepts electrons to produce FADH2.  These molecules will deliver these electrons to a respiratory chain, where they will travel until be accepted by O2 to form H2O (some protons are also necessary).

the correct answer is - no.

winnipeg, canada, is not further away from the equator than moscow, russia, in fact moscow is the city that is further away from the equator. moscow is on a latitude of 55.7558° north, while winnipeg is on a latitude of 49.8951° north, thus putting moscow by 5.8607° further away from the equator than winnipeg is.
