What organelle modifies proteins chemically then repackages?
chapter 7-eukaryotic cell structure and function
| A | B |
|---|---|
| golgi apparatus | modifies proteins chemically, then repackages them |
| chloroplast | contains inner membranes arranged in stacks of membranous sacs called grana |
| plastids | plant organelles that store starches or lipids or that contain pigments |
What modifies proteins after they are synthesized?
The endoplasmic reticulum (ER) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids.
What chemically modifies proteins in a cell?
Golgi apparati
Larger modifications, such as the addition of a carbohydrate group, occur to create glycoproteins in specialized organelles termed Golgi apparati. Modifications change the charge of the protein, and often cause a change in the protein’s activity level.
What part of the cell modifies sorts and repackages proteins?
The Golgi apparatus
The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER.
Which organelle is flattened stack of membranes that modifies sorts and packages proteins into SCS called vesicles?
complex) A flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It produces the membranes that surround the lysosomes. The Golgi body packages proteins and carbohydrates into membrane-bound vesicles for “export” from the cell.
Which of the following modifies proteins and lipids by adding carbohydrates?
The endoplasmic reticulum
The endoplasmic reticulum (ER) ((Figure)) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids.
Which of the following produces and modifies polysaccharides that will be secreted?
The Golgi body
The Golgi body will produce and modify polysaccharides that will be secreted from the cell.
