Does the size or the speed of a molecule determines whether it can pass through the pores of a membrane?
The speed doesn't necessarily determine the permeability, but the size does. Smaller molecules such as O2 can easily enter the cell while CO2 leaves the cell. There are other criteria that also determines whether a molecule can pass through the plasma membrane such as its solubility. Fat soluble molecules such as steroids can easily pass through the membrane.
What does nuclear envelope pores mean?
The nuclear envelope is the nuclear membrane. Nuclear pores are openings in the nuclear membrane that allow for the movement of materials into and out of the nucleus. For example, the mRNA that forms in the nucleus during DNA transcription leaves the nucleus through the pores in the nuclear membrane, and attaches to ribosomes in the cytoplasm and rough endoplasmic reticulum.
What are the two characteristics of a molecule that will keep it from passing through a membrane and how does each keep the molecule from passing through?
Two characteristics that can prevent a molecule from passing through a membrane are size and charge. Larger molecules may be too big to fit through the pores in the membrane, while charged molecules may be repelled by the hydrophobic core of the membrane.
What are cell membrane pores are made of?
Cell membrane pores are made up of protein.
What molecule diffuses out of the pores of the leaf?
The molecule that diffuses out of the pores of the leaf is called water vapor.
What forms pores in the cell membrane?
Pores in the cell membrane can be formed by protein complexes called ion channels or porins. Ion channels allow specific ions to pass through the membrane, while porins allow the passage of larger molecules or solutes. These pores play crucial roles in regulating the movement of substances in and out of the cell.
What are the components of the nucleus?
Nucleus has nucleolus, nuclear membrane and the genome. Nuclear membrane containing pores that transport molecule across the membrane. Nucleolus makes rRNA and ribosomes. Genome has all chromosomal DNA that express a gene or a character.
Do materials move into the nucleus do pores in the nuclear membrane?
Yes, materials move into the nucleus through pores in the nuclear membrane.
Double membrane with pores?
plastids
What is another word for membrane?
pores
Openings in the nuclear membrane?
Nuclear pores are the openings in the nuclear membrane that allow the passage of molecules like proteins and RNA between the nucleus and the cytoplasm. These pores are essential for maintaining communication and regulating transport between the nucleus and the rest of the cell.
Does a dialysis membraneave pores?
Yes, a dialysis membrane has pores that allow for the separation of solutes based on their size and charge. The size of the pores can vary depending on the specific dialysis membrane being used.
