How are proteins and lipids secreted out of the cell?
Proteins are typically secreted out of the cell through the process of exocytosis, where vesicles containing the proteins fuse with the cell membrane and release their contents outside the cell. Lipids can be secreted out of the cell by being packaged into vesicles called exosomes, which are then released into the extracellular space through exocytosis or by budding off from the cell membrane.
Where proteins are processed and packaged?
Proteins are produced in all cells by protein synthesis. It requires the mRNA molecule produced from DNA in nucleus. Once it is transported to cytoplasm, ribosomes and tRNA molecules and enzymes will carry out protein synthesis.
Does the mitochondria package proteins?
No, the mitochondria do not package proteins. Their main function is to generate energy in the form of ATP through cellular respiration.
What happens after the synthesis of proteins?
After proteins get modified in the Endoplasmic Reticulum, they are transported through the golgi apparatus where they get packaged into vesicles to late be secreted out of the cell or to be used within the cell.
Most of the food and waste materials that move into and out of a cell pass through?
The cell membrane. It controls the passage of substances in and out of the cell through a process called selective permeability. This ensures that only necessary molecules enter the cell and waste products are removed.
What is he process in which proteins are packaged by the Golgi bodies?
Proteins are processed and modified as they move through the Golgi apparatus. This includes glycosylation, sorting, and packaging the proteins into vesicles. The Golgi then directs these vesicles to their final destination within the cell or for secretion outside of the cell.

How are new proteins moved to the surface of the cells and secreted?
New proteins are moved to the cell surface and secreted through a process called vesicle trafficking. Proteins destined for the cell surface are synthesized by ribosomes attached to the endoplasmic reticulum, folded properly in the Golgi apparatus, and then packaged into vesicles for transport to the cell membrane for secretion. These vesicles fuse with the plasma membrane, releasing the proteins outside the cell.

The cell membrane. It controls the passage of substances in and out of the cell through a process called selective permeability. This ensures that only necessary molecules enter the cell and waste products are removed.
Why are proteins not removed by nephrons?
Proteins are not typically removed by nephrons because they are too large to pass through the filtration barrier in the glomerulus. Normal kidney function should not allow proteins to be filtered out, however, if proteins are detected in the urine, it may indicate a problem with the filtration barrier or kidney function.
How do really big molecules get out of the cell?
Really big molecules, such as proteins or DNA, can exit the cell through a process called exocytosis. In exocytosis, the large molecule is packaged into a vesicle within the cell and then fuses with the cell membrane, releasing the molecule outside the cell. This is an active process that requires energy.
What is deamination of protein?
Deamination is the bodily process in which amino groups are removed from excess proteins. This happens most often in the liver, though it also occurs in the kidneys. Deamination allows the system to convert excess amino acids into usable resources such as hydrogen and carbon. The process also plays a vital role in removing nitrogen waste from the body. Amino groups discarded as a result of the process are converted into ammonia, which is later expelled from the body through urination.
Process by which sediment is removed from its source definition?
Sediment is removed from its source through the process of Erosion.
Describe the movement of proteins through the internal membrane system of a cell?
Proteins are synthesized by ribosomes in the cytoplasm and are then translocated into the endoplasmic reticulum (ER) for processing. From the ER, proteins are sent to the Golgi apparatus for further modification and sorting. Finally, proteins are packaged into vesicles and transported to their final destination within the cell, such as the plasma membrane or lysosomes.
