What is the job for cell membrane?
The cell membrane acts as a protective barrier that regulates the passage of substances in and out of the cell. It also helps maintain the cell's shape and structure, and plays a crucial role in cell communication with its environment.
What is an analogy for a cell pore?
A cell pore can be compared to a gate or a doorway that regulates the entry and exit of molecules in and out of the cell. Just like how a gate controls access to a fenced area, cell pores control the movement of substances in and out of the cell.
What object can a cell membrane be?
A cell membrane can be compared to a barrier or a gatekeeper. It regulates the movement of substances in and out of the cell, maintaining internal conditions necessary for the cell to function properly.
What is an analogy for nuclear envelope?
The nuclear envelope is the membrane that basically isthe nucleus of a cell. It holds all the cell's DNA, and keeps it separate from everything else. It's like a mini cell, inside a cell. Think of it sort of like a wiffle ball. It's covered in tiny pores that allow small things, like RNA, to pass through it. At the same time, however, it keeps the chromosomes in, and does not allow larger proteins or organelles to pass through.
What part of the cell is like a gate?
In this analogy, the cell membrane is like a wall, keeping what's in the cell inside, and what is outside of the cell out. However, there are "gates" called receptors. Receptors are large protein molecules embedded in the membrane, with one end outside and one end inside. Different gates, or receptors, permit certain things to enter. For example a glucose receptor lets glucose enter the cell. When a glucose molecule passes a glucose receptor, the glucose molecule is attracted to the receptor by an electric charge. It then binds to the receptor, but now the balance of the charges in the protein molecule has been changed, so the protein molecule changes shape. When it changes shape, it pulls the glucose into the cell and then lets go of the glucose. Now the protein is free to return to its original shape, and the glucose is inside the cell.

What type of molecule acts as a gate for substances to enter or leave the cell?
plasma membrane
What does the cell membrane do for a animal cell?
The cell membrane is used to keep the cytoplasm in place, give structure to the cell and i believe it acts as a gate keeper for chemicals. Hope this helps. :)
What is a cell membrane similar to?
A cell membrane is similar to a security gate as it selectively allows certain molecules to enter or exit the cell, just like a gate only lets specific individuals through. It also acts as a barrier to protect the cell's contents, much like how a gate can protect a space from unauthorized entry.
When is that the 'NAND' logic gate can function as a 'NOT' logic gate?
When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
Cell membrane analogy?
The cell membrane can be compared to a fence around a house. Just as a fence regulates what enters and exits the property, the cell membrane controls what substances come in and out of the cell. Additionally, like a fence, the cell membrane provides protection and support for the cell.
What is the function of the cell membrane and which cells have membrane?
The function of the cell membrane is to let things in and out of the cell. It's like a gate to the cell. Prokaryotic and eukaryotic cells have cell membranes.
Why mosfet has insulated gate?
The SiO2 layer acts as an insulator and also it provides high input impedance to the MOSFET. This insulation is needed so that a circuit with high EMI or loads which generate back emf (motors) can be driven by applying gate current from a common circuit.
Which layer is composed of silicon and aluminum?
The layer composed of silicon and aluminum is the insulating layer in a metal-oxide-semiconductor (MOS) structure, commonly known as the gate oxide layer. This layer is crucial in controlling the flow of current in the transistor by applying a voltage at the gate terminal.
What is a good analogy for cell wall?
It could be a gate. It is a gate because the door is the cell membrane. See you need to get past the cell wall before the cell membrane.
Can NAND gate acts a ANDgate?
Yes, but only if its output is logically inverted (a AND gate's behavior is a direct opposite of a NAND gate's behavior, logically).
How can you replace end gate or gate and not gate with a nand gate?
when the two inputs are shorted, a NAND gate acts like a NOT gate. hence AND = NAND + NOT For OR gate, inverse both the inputs before connecting them to a NAND gate. So three NAND gates would be needed.
