Metabolic Pathways
Energy is released by breaking down nutrients: glycolysis, the Krebs cycle, and oxidative phosphorylation produce ATP, the body’s energy currency.
2
Vitamins
| Group | Examples | Note |
|---|---|---|
| Fat-soluble | A, D, E, K | Stored in body |
| Water-soluble | B-complex, C | Not stored, need daily |
⚠️ Common Mistake
Fat-soluble vitamins (A, D, E, K) can build up to toxic levels; water-soluble ones are excreted in urine.
3
Minerals
Macrominerals (calcium, potassium, sodium) and trace minerals (iron, iodine, zinc) regulate body processes. Iron deficiency causes anemia; iodine deficiency causes goiter.
4
Deficiency Diseases
| Nutrient | Deficiency |
|---|---|
| Vitamin A | Night blindness |
| Vitamin C | Scurvy |
| Vitamin D | Rickets |
| Iron | Anemia |
| Iodine | Goiter |
