Final answer:

Digestion begins in the mouth, nutrients go to the liver first, and mitochondria supply energy for cell use.

True. The process of digestion actually starts in the mouth with the breakdown of carbohydrates by enzymes in saliva, not in the stomach.

True. Nutrients absorbed into the bloodstream from the digestive tract first go to the liver through the portal vein for processing.
