Do exocytosis and endocytosis both need to consume energy?

1. Energy needs to be consumed, because exocytosis and exocytosis both need the help of dynamin to complete the separation of vesicles from the membrane, and this process needs to consume energy in GTP.

2. The carrier exists on the membrane, because cytocytocytosis is non-transmembrane transport and does not pass through the biofilm.

So endocytocytosis does not require a carrier.

3. Endocytosis and exocytosis are non-transmembrane transport and do not pass through biofilms. When the contents of the vesicle are excreted or enter the cell, the vesicle will break into the cell membrane.

Yes. There is no explanation for this in secondary school. But students who have studied the Olympiad should understand.

In fact, the flow of the cell membrane is not just the flow of the flow, and the cell has a network cytoskeleton formed by actin. These include microtubules, microfilaments, and intermediate filaments.

Changes in cell shape, composition, and cytoplasmic circulation are all related to the movement of these proteins.

Endocytosis is the biological effect of the continuous reorganization of these proteins.

Of course, it consumes energy.

It needs to be consumed.

This needs to rely on the flow of the cell membrane to complete endocytosis and efflux, which of course consumes energy.

Yes, all require energy consumption. Both exocytosis and exocytosis require the help of dynamin to complete the separation of vesicles from the membrane, a process that consumes energy from the GTP.

Yes, only active transport and endocytocytosis need to consume energy.

Endocytocytosis requires energy. Both exocytosis and exocytosis require the help of activated proteins to complete the separation of vesicles from the membrane, a process that consumes energy from the GTP. Endocytosis is the process of encircling foreign macromolecules and particulate matter into a membrane bubble through the invagination of the plasma membrane, and then detaching from the cell membrane to transport the material into the cell.

Exocytosis is the excretion of the remnants of exogenous substances ingested by endocytosis and pinocytosis after intracellular degradation. Endocytocytosis requires energy. Because exocytosis and exocytosis both require the help of activated proteins to complete the separation of vesicles from the membrane, this process requires the energy in GTP.

Endocytosis is an important way for cells to obtain macromolecules and granular matter from outside the cell, and it is a physiological phenomenon that is ubiquitous in eukaryotic cells. Extracellular substances are encapsulated through the plasma membrane, and the plasma membrane is invaginated and forms membrane-coated vesicles, which are detached from the plasma membrane into the human cell and produce a series of physiological activities and physiological functions in the cell. Exocytosis, which is the process of transporting the substances in the membrane vesicle out of the cell through the fusion of the secretory vesicle or other membrane vacuoles with the plasma membrane, is the way of transporting macromolecular substances in the cell, the cell secretes exotic substances through exocytosis, and the pancreatic cells secrete prozymogen granules (proteins) is a kind of exocytosis.

Energy needs to be consumed because both exocytosis and exocytosis require the help of initiating proteins to complete the separation of the vesicles from the membrane, a process that consumes energy in the GTP. The carrier exists on the membrane, and the carrier is not required for endocytocytocytosis and exocytosis is non-transmembrane transport and does not pass through the biofilm.

Endocytosis

Endocytosis or endocytosis is an important way for cells to obtain macromolecules and granular substances from outside the cell, and it is a physiological phenomenon that is prevalent in eukaryotic cells. Extracellular substances are encapsulated through the plasma membrane, and the plasma membrane is invaginated and forms membrane-coated vesicles, which are separated from the plasma membrane into the human cell and produce a series of physiological activities and physiological functions in the cell.

Endocytosis is closely related to a variety of life activities, such as immune response, neurotransmitter trafficking, cell signal transduction, and metabolic balance of cells and tissues. In recent years, with the deepening of research on endocytosis, we have a deeper understanding of the function and mechanism of endocytosis.

exocytosis

Expulsion, also known as expulsion, is the excretion of the residue of exogenous substances ingested by exocytosis and pinocytosis after intracellular degradation.

Phagosomes are formed by the ingestion of exogenous substances by endocytosis and pinocytosis by engulfing empty cells in the interior. Subsequently, the phagosome will fuse with the primary lysosomes to form secondary lysosomes.

It has been advocated that secondary lysosomes formed by ingestion of exogenous substances should be called xenolysosomes. This distinguishes it from autolysosomes formed by ingestion of endogenous substances. In secondary lysosomes, exogenous substances will be degraded by lysosomal hydrolase enzymes.

The energies are as follows:Energy is needed. Endocytosis or endocytosis is an important way for cells to obtain macromolecules and granular substances from outside the cell, and it is a physiological phenomenon that is prevalent in eukaryotic cells.

Extracellular substances are encapsulated through the plasma membrane, and the plasma membrane is invaginated and dissolves and forms membrane-coated vesicles, which are separated from the plasma membrane into the human cell and produce a series of physiological activities and physiological functions in the cell.

Introduction:

There is no unified or unified definition of cell, and the more common reference is that cell is the basic structural and functional unit of living organisms.

It is known that all organisms except viruses are composed of cells, but the life activities of viruses must also be reflected in cells.

Generally speaking, most microorganisms such as bacteria and protozoa are composed of a single cell, that is, single-celled organisms, while higher plants and higher animals are multicellular organisms. Cells can be divided into two categories: prokaryotic cells and eukaryotic cells, but some people have proposed that they should be divided into three categories, that is, the ancient karyotic cells that originally belonged to prokaryotic cells should be separated as a parallel category. The discipline that studies cells is called cell biology.
