Where do free hydrogen ions normally come from in the human body? Select all that apply

• Humans breathe in free hydrogen ions in the atmosphere from the buildup of greenhouse gases.

• Hydrochloric acid is produced in the stomach and is a normal source of free hydrogen ions

• Ingestion of spicy foods increase the concentration of uncontrolled free hydrogen ions.

• Free hydrogen ions are produced by-products of carbohydrate and protein metabolism
