sweat gland - eccrine
The sweat gland that produces a secretion containing proteins and fats, in addition to water and salt, is the apocrine gland. These glands are primarily located in areas such as the armpits and groin and become active during puberty. The secretion from apocrine glands is thicker and can contribute to body odor when broken down by bacteria on the skin.
sweat gland - eccrine
A cell that releases exosomes, which are small vesicles containing cell fragments and proteins, is an example of a secretion that contains cell fragments. Exosomes play roles in cell communication and the transfer of biomolecules between cells.
Proteins
The organelle that packages and stores proteins is the Golgi apparatus. It produces vesicles containing proteins that are ready to be transported to other parts of the cell or secreted outside the cell.
Proteins synthesized in the rough endoplasmic reticulum (ER) are packaged into vesicles and transported to the Golgi apparatus, where they undergo modifications and sorting. From the Golgi, proteins are sent to their final destinations, which could include lysosomes, the plasma membrane, or secretion outside the cell. Vesicles containing proteins destined for secretion fuse with the plasma membrane, releasing their contents into the extracellular space. This process is crucial for cellular communication and maintaining homeostasis.
Transport proteins are not responsible for the secretion. Golgi vesicles transport proteins. Proteins synthesis occur in cytoplasm.
Golgi apparatus
there is no such thing as a secretion vesicle.although there is a secretory vesicle;Which is a membrane bound vesicle derived from the Golgi apparatus and containing material that is to be released from the cell.
ribosomes (because they make proteins). The ribosomes will usually be found associated with the endoplasmic reticulum so you'll see lots of rough ER.
Proteins in the kidney are involved in filtration, reabsorption, and secretion. Filtration allows proteins to pass through the glomerulus, reabsorption helps retrieve essential substances like glucose and amino acids, and secretion involves removing waste products and excess substances from the blood.
The endoplasmic reticulum (ER) is responsible for synthesizing and modifying proteins that are intended for secretion from the cell. These proteins undergo various post-translational modifications, such as glycosylation and disulfide bond formation, within the lumen of the ER before being transported to the Golgi apparatus for further processing and eventual secretion.
