Adaptation helps the plant, it is passed down to its seedlings. If the adaptation does not help, the plant will not survive to reproduce. Each of the plants here in the desert, at one point or another, developed adaptations that made them more likely to survive than the plants without these adaptations.
Another valuable attribute of cam plants is their capability for idling metabolism during droughts. When cam plants become water-stressed, the stomates remain closed both day and night; gas exchange and water loss nearly cease. The plant, however, maintains a low level of metabolism in the still-moist tissues.
Exogenous substrate supply plays an important role in modulating the acute metabolic responses to endurance exercise. For instance, carbohydrate intake before and during exercise (6, 13, 14, 17, 21, 35, 39), or alternatively carbohydrate infusion (22, 36), stimulates the contribution of blood glucose to the metabolic substrate pool fueling muscle contractions and inhibits fat oxidation.
