Answer: No
Explanation: Elodea or Paramecium live in fresh-water lakes and they are not adaptive to salt-water. Oceans are salty and the cells will lose water due to osmosis and eventually dry up and fall apart.
Answer: C
Explanation In any of the answer choices doesn't say tat its possible copper to conduct electricity. But in C its says it can exchange electricity.
Answer:
Electron transport chain and ATP synthase
Explanation:
The inner mitochondrial membrane contains an electron transport chain and ATP synthesis. Four membrane protein complexes serve as the electron carriers and are embedded in the inner mitochondrial membrane. These protein complexes are called complex I, II, III and IV. Transfer of electrons from NADH and FADH2 to terminal electron acceptor oxygen occurs via these protein complexes.
During electron transfer, the pumping of protons towards the inner mitochondrial membrane creates an electrochemical gradient. The downhill transfer of protons back to the matrix via proton channel of ATP synthase drives phosphorylation of ADP. Therefore, presence of all the protein complexes of the electron transport chain and ATP synthase is required for electron transfer and ATP synthesis.
Answer:
The correct answer will be option-C.
Explanation:
The proton motive force is the force generated by the movement and difference of the charge inside and outside the membrane. The proton motive force is generated due to the electron transport chain as the flow of electron causes the movement of hydrogen ions from the matrix to the inter-membrane space.
This leads to the increase of H⁺ ion concentration in inter-membrane space and lowering of the H⁺ ions in the matrix. This difference in the charges causes the generation of force called proton motive force which helps the synthesis of ATP.
Thus, Option-C is the correct answer.
