Answer: The electron transport chain consists of complexes which are the proton pump for the hydrogen ions across the mitochondrial membrane which allows the synthesis of the ATP (energy currency).
Explanation:
The electron transport chain occurs in the mitochondria. ATP synthase present in the inner mitochondrial membrane is a carrier of electron. FADH2 AND NADH two molecules supply high energy electrons from the citric acid cycle from the electron transport chain at complex I (NADH coenzyme Q reductase) and II (succinate dehydrogenase)respectively.
Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells.
The answer to number four is A
Cassini was the name of the satellite.
The correct answer is b: cattle on rangeland. A point source of pollution occurs from a single identifiable and usually spatially narrow source. These sources of pollution are usually relatively easily to quantify and manage. In contrast, a non-point source of pollution, such as cattle on rangeland or irrigated agriculture, is variable on both spatial and temporal scales. These sources of pollution are difficult to quantify and manage.
