Component
Renal ammonia production
Renal generation of total ammonia; assays may combine NH3 and NH4+.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Renal mitochondria from potassium-depleted rats produced more ammonia during glutamine-metabolism assays after three days of potassium-free feeding.
Experimental context and source evidence
- availability_state
- nutrient_deficiency Imported condition classification; unverified.
- cross_nutrient
- Potassium depletion changes mitochondrial glutamine nitrogen metabolism; enzyme capacity and substrate entry need separate accounting.
- endpoint
- Renal mitochondria from potassium-depleted rats produced more ammonia during glutamine-metabolism assays after three days of potassium-free feeding.
- experimental-exposure
- Rats on potassium-free diet with renal mitochondrial and cortical-tubule ammonia assays during depletion and potassium refeeding.
- experimental_model
- Rats on potassium-free diet with renal mitochondrial and cortical-tubule ammonia assays during depletion and potassium refeeding.
- limitations
- Isolated mitochondrial assay, not whole-body bicarbonate balance. Glutaminase activity rose earlier than ammonia flux; mitochondrial glutamine entry was proposed as a limiting step.
