Ecological Adaptations in Xerophytes Xerophytes are group of plants that survive in dry regions. They grow in deserts, dry hilly regions. They adapt themselves to dry and sandy or …
Oxidative phosphorylation Oxidative phosphorylation is the synthesis of energy-rich ATP molecules with the help of energy liberated during oxidation of reduced coenzymes ( i.e.,NADH2 and FADH2), produced in respiration. …
Anaerobic respiration: Anaerobic respiration is a process of release of energy in enzymatically controlled incomplete degradation of organic food without oxygen being used as oxidant. It is an exclusive …
