Answer 1

1.

a.) Initial breakdown of carbohydrate	(5) Glycolysis (Breakdown of sugar into Pyruvate, it's an anaerobic process)
b.) Initial breakdown of fat	(2) Fatty acid oxidation
c.) Made by all 3 energy nutrient	(3) Acetyl coA Acetyl coA molecule participate in reaction in protein, lipid and carbohydrate.
d.) Removal of nitrogen from an amino acid	(4) Deamination
e.) Most ATP is produced	(1) Electron transport chain (occurs in inner mitochondrial membrane)

2. (d) Results in the formation of pyruvate

Glycolysis is the breakdown of Glucose into Pyruvate after going through many biological reaction.
