Answer:
True
Explanation:
During the evolution of eukaryotic cells, the complexity of size and their functions increased, so that a proportional increase in the surface of the <u>cell membrane</u> would be necessary, making it possible for the cell to perform several functions at the same time.
Through differentiations of the structures, it was possible to develop intracellular membranes in the form of organelles capable of performing various functions at the same time, such as cellular respiration and digestion.
Answer
The correct sequence is given below.
Explanation:
A. NAD+ (It recieves electrons directly from substrate in glycolytic as well as Citric acid cycle reactions)
B. Oxidoreductase (It is present as complex I termed NAD+-CoQ oxidoreductase. It receives electrons from NADH)
C. Quinone (It is present as Ubiquinone in complex III of Electron transport chain. It receives electrons from NADH and FADH2)
D. Terminal oxidase (It is complex IV of electron transport chain termed as Cyt c oxidase)
E. Oxygen (It is the final acceptor of electrons and gets reduced to water)
Answer:
These results show that the body regulates its salt and water balance not only by releasing excess sodium in urine, but by actively retaining or releasing water in urine. The advantage of this mechanism is that the long-term maintenance of body fluids isn't as dependent on external water sources as once believed.
