The unit membrane, typically referring to the plasma membrane of cells, consists of a phospholipid bilayer with embedded proteins that regulate the passage of substances. In contrast, the mitochondrial envelope comprises two distinct membranes: an outer membrane that is smooth and permeable to small molecules, and an inner membrane that is highly folded into cristae, housing the machinery for ATP production. While both structures serve as barriers and interfaces for cellular processes, their composition and functions differ significantly, reflecting their roles in cellular metabolism and energy production.
What else can I help you with?
What are mitochondria surrounded by?
Mitochondria are surrounded by membranes.They have two membranes.
Is nucleus envelope in nucleus?
Yes, the nuclear envelope is a double membrane structure that surrounds the nucleus in a eukaryotic cell. It is made up of an outer membrane and an inner membrane, with nuclear pores allowing for the exchange of materials between the nucleus and the cytoplasm.
What are the main difference between mitochondrial and chloroplast DNA's?
The ribosomes of chloroplasts closely resemble bacterial ribosomes, while mitochondrial ribosomes show both similarities and differences that make their origin more difficult to trace.
What is the characteristics of nuclear envelope?
The nuclear envelope is a double-membrane structure that surrounds the nucleus of eukaryotic cells. It consists of an inner and outer membrane, with the space between them known as the perinuclear space. The nuclear envelope is punctuated by nuclear pores, which regulate the transport of molecules such as RNA and proteins between the nucleus and the cytoplasm. Additionally, it plays a role in maintaining the shape of the nucleus and organizing chromatin.
Double membrane covered with pores?
This describes the structure of the nuclear envelope, which surrounds the cell nucleus. The double membrane provides a protective barrier, while the pores allow for the exchange of molecules such as proteins and RNA between the nucleus and the cytoplasm.

What is the Membrane that surrounds nucleus?
the nuclear envelope
What are two differences between the goodyear blimps of today and the airship Hindenburg?
Size and type of gas contained in the envelope.
Is the nuclear envelope composed of two bilayers?
There are two phospholipid bilayers that are present in the nuclear envelope. They are the inner and outer phospholipid bilayers. Nuclear envelope are also referred to as karyotheca, nucleolemma or nuclear membrane.
How and why do inner and outer mitochondrial membranes differ in permeability?
The inner mitochondrial membrane is selectively permeable and highly impermeable to ions and polar molecules due to the presence of transport proteins like ATP synthase and carriers for metabolites. This allows for the establishment of a proton gradient necessary for ATP production. In contrast, the outer mitochondrial membrane is more permeable and allows for the passage of ions, metabolites, and small proteins, facilitating communication and transport of molecules between the mitochondria and the cytosol.
Is the nucleus completely isolated from the cytoplasm of the cell by the nuclear envelope?
No, the nucleus is not completely isolated from the cytoplasm. The nuclear envelope has pores that allow for the exchange of molecules between the nucleus and cytoplasm. This allows for communication and transport of molecules between the two compartments.
