Answer:
The correct answer would be "NADH delivers its electrons to complex I and FADH₂ deliver its electrons to complex II" in cellular respiration.
There are mainly four complexes associated with electron transport chain of cellular respiration.
Complex I or NADH: ubiquinone oxidoreductase is the complex at which NADH is oxidized to form NAD⁺. The free electrons are transported with the help of ubiquinone.
Complex II or succinate dehydrogenase is the complex associated with oxidation of FADH₂ to FAD⁺. It also transports the free electrons with the help of the ubiquinone pool.
Complex III or cytochrome bc1 complex transport free electrons from ubiquinone to the cytochrome C which is a water-soluble electron carrier.
Complex IV or cytochrome c oxidase transport the free electrons to oxygen to form water.
Answer: Energy is not recycled once it passes from producer to consumer to decomposer.
The energy flow in an ecosystem in the form of food from one organism to other is food chain. It comprises mainly of three types of organisms producers or autotrophs, consumers or heterotrophs and decomposers. The energy flow in food chain or food web is unidirectional from plants which are the primary producers to primary consumers or herbivores, then to secondary consumers or carnivores and finally to the decomposers. On its unidirectional flow the energy is lost in different form such as heat loss, decay, respiration etc. The energy passed from one level to another is not the same and gets lost in the process so when the energy is received from one tropic level to another it is always less than that received by the previous tropic level.
