Endomembrane System: Protein Secretion definitions Flashcards

A network of interconnected, membrane-bound organelles in eukaryotic cells responsible for protein secretion, cellular digestion, and transport via vesicles.

The process by which proteins are synthesized in the rough ER, processed in the Golgi apparatus, and transported via vesicles to the cell membrane for release outside the cell.

A cell type with membrane-bound organelles, including a nucleus, endoplasmic reticulum, and Golgi apparatus, facilitating complex processes like protein secretion and cellular digestion.

Small membrane-bound sacs that transport and store substances within a cell, facilitating communication between organelles in the endomembrane system.

The breakdown of cellular components by lysosomes, peroxisomes, and vacuoles, involving enzymatic reactions to recycle or dispose of cellular waste and damaged organelles.

A double-membrane structure surrounding the nucleus, controlling the flow of materials in and out via nuclear pores.

A network of membranous tubules within eukaryotic cells, involved in protein and lipid synthesis, and transport. It has two types: rough (with ribosomes) and smooth (without ribosomes).

A membrane-bound organelle in eukaryotic cells that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Organelles that digest cellular waste and foreign material using hydrolytic enzymes, crucial for cellular cleanup and recycling processes.

Organelles that detoxify harmful substances and break down fatty acids using oxidative enzymes, producing hydrogen peroxide as a byproduct.

A dense region within the nucleus responsible for producing ribosomal RNA (rRNA) and assembling ribosomes, essential for protein synthesis.

A small, membrane-bound sac that transports proteins and other molecules between organelles within the endomembrane system or to the cell membrane for secretion.
