Final answer:
The provided information does not specify a false statement about the potassium channel structure in Streptomyces lividans. To determine a false statement, a list of statements would be required. The question statements about sodium-potassium pumps and vesicles provide true or false clarity regarding their functions and origin.
Step-by-step explanation:
The statement about the structure of the potassium channel from the bacterium Streptomyces lividans that is false is not specified in the information provided. In order to determine which statement is false, one would need a list of statements about the channel's structure to assess. However, for general information, potassium channels allow potassium ions to pass through the cell membrane and are vital for various cellular processes.
The sodium-potassium pump is essential for maintaining the cell's electrochemical gradient. The shape change of the carrier protein in the sodium-potassium pump after sodium ions bind is significant because it allows the pump to change its affinity for sodium and potassium, leading to the release of sodium ions outside of the cell and the uptake of potassium ions into the cell. If a substance like ouabain blocks the pump, the balance of sodium and potassium across the cell membrane would be disrupted, potentially leading to cell dysfunction or death.
Regarding the provided question statements, it's True that the sodium-potassium pump uses one protein to pump both sodium and potassium ions. However, the statement "Vesicles are made of the nuclear membrane" is False; vesicles are not made of the nuclear membrane but are instead formed from parts of the cell membrane or the membranes of the endoplasmic reticulum and Golgi apparatus.
