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.
Adenosine triphosphate (ATP) is the primary molecule that stores and transfers energy in a cell. ATP is produced during cellular respiration, where glucose is broken down to release energy that is then stored in the form of ATP molecules. This ATP can be used by the cell to power various cellular processes and reactions.
Proteins destined for secretion are modified in the endoplasmic reticulum and Golgi apparatus to become glycoproteins. These carbohydrate modifications help with protein folding, stability, and recognition by other cells. Glycoproteins also play a role in cell-cell communication and immune response.
Proteins
Ribosomes and endoplasmic reticulum. Ribosomes are responsible for protein synthesis, while the endoplasmic reticulum aids in protein folding and modification before secretion.
Transport proteins are not responsible for the secretion. Golgi vesicles transport proteins. Proteins synthesis occur in cytoplasm.
Golgi apparatus
A secretion vesicle is a membrane-bound organelle within a cell that contains substances such as proteins or hormones that are to be released from the cell. These vesicles are involved in the process of exocytosis, where the contents are expelled from the cell to carry out various functions.
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.
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.
