What characteristic of cell membranes may explain why fat-soluble substances such as chloroform and other rapidly affect cells?
The lipid bilayer structure of cell membranes allows fat-soluble substances like chloroform to easily pass through them. This is because these substances can dissolve in the hydrophobic interior of the lipid bilayer, making it easier for them to enter the cells quickly and affect them rapidly.

What characteristics of cell membranes may explain why fat soluble substances such as chloroform and ether rapidly affect cells?
Cell membranes are composed of a lipid bilayer, which is impermeable to water-soluble substances but allows fat-soluble substances to easily pass through. Fat-soluble substances like chloroform and ether can dissolve in the lipid bilayer of the cell membrane and penetrate cells rapidly, leading to their rapid effects on cells.
What characteristics of cell membranes may explain why fat-soluble substances such as chloroform and ether rapidly affect cells?
The fact that cell membranes are semi-permiable creates openings for the substances to enter.
Why do chloroform and ether rapidly affect cells?
Chloroform and ether are both volatile organic compounds that can rapidly penetrate cell membranes. Once inside the cell, they disrupt cellular processes by interfering with protein function, disrupting lipid membranes, and potentially causing oxidative stress. This can lead to cell death or dysfunction.
What is the effect of chloroform on membrane permeability?
Chloroform can disrupt the structure of cell membranes, leading to increased permeability. This disruption can cause leakage of cellular contents and loss of membrane integrity, ultimately leading to cell damage or death.
What is the Use of chloroform in DNA extraction from organisms?
Chloroform is used in DNA extraction to separate DNA from proteins and lipids. It helps to denature and precipitate the proteins and disrupt the cell membranes to release the DNA. The DNA can then be further purified and isolated for downstream applications.

What is the key characteristic of lipids that enables them to keep substances form penetrating cell membrans?
The key characteristic of lipids that enables them to prevent substances from penetrating cell membranes is their hydrophobic nature. Lipids are primarily composed of long hydrocarbon chains that are nonpolar, making them insoluble in water. This hydrophobic property allows lipid molecules to form a bilayer structure in cell membranes, creating a barrier that restricts the passage of polar and charged substances while allowing selective permeability for certain molecules.
What are membranes that allow only certain substances to pass through them?
Semi permeable membranes.

Do All membranes have exactly the same permeability characteristics?
No, all membranes do not have exactly the same permeability characteristics. Different membranes can have varying levels of permeability to different substances based on their structure and composition. Some membranes may be more selective in what substances they allow to pass through, while others may be more permeable.
What supervises the substances entering and exiting the cytoplasm?
