potassium

Potassium is needed for generation and conduction of action potential signals in neurons and muscle fibers. Cobalt is required for erythropoiesis. Sulfur is a component of hormones and vitamins, and regulates several body activities. Manganese activates enzymes, is required for hemoglobin synthesis, urea formation, growth, reproduction, lactation, bone formation, inhibition of cell damage, and possibly production and release of insulin.
substrate level
(Substrate Phosphorylation)

There are three mechanisms of phosphorylation: substrate-level phosphorylation, oxidative phosphorylation and photophosphorylation. An example of substrate-level phosphorylation is the addition of a phosphate group to an ADP molecule to generate an ATP molecule. Oxidative phosphorylation is the removal of electrons from organic compounds to pass them through an electron transport chain to oxygen molecules. Photophosphorylation only occurs in chlorophyll-containing plant cells or bacteria that contain light-absorbing pigments.
kilocalorie

A kilocalorie is often used to express the energy content of foods (1 kcal = 1,000 cal). A calorie (cal) is defined as the amount of energy required to raise the temperature of 1 gr of water by 1 degree Celsius. Calorigenic effect is when thyroid hormones increase BMR by stimulating cellular respiration. The basal state refers to the metabolic rate measured when the body is in a quiet, resting and fasting state.
