What else can I help you with?
What can proteins made on ribosomes be further modified within?
Proteins made on ribosomes can be further modified within the endoplasmic reticulum and Golgi apparatus. These organelles play a role in post-translational modifications such as glycosylation, phosphorylation, and addition of signal sequences that are important for protein function and localization within the cell.
What part of a cell holds proteins?
Proteins are typically synthesized and modified in the endoplasmic reticulum (ER), a network of membrane-bound tubules and sacs. After synthesis, proteins may be further modified and packaged in the Golgi apparatus before being transported to their final destination within or outside the cell.
What process take place in the rough endoplasmic reticulum?
Protein synthesis, folding, and modification occur in the rough endoplasmic reticulum. Ribosomes attached to the membrane of the rough endoplasmic reticulum synthesize proteins that are then processed and modified before being transported to other parts of the cell.
Where proteins made of?
Proteins are made of amino acids.
Why proteins made by free ribosomes free of carbohydrates?
These proteins are not directed to the Golgi for modification. there are two paths for synthesis of proteins: 1) By free ribosomes in the cytosol. Protein is left in the cytosol with no carbohydrate modifications 2) By ribosomes bound to the ER. The protein is transported into the ER during synthesis and transported to the golgi for modification.
Where are proteins made and modified for secretion from cell?
Golgi apparatus
What are proteins modified within?
The Golgi Apparatus modifies and packages proteins.
Are enzymes derived proteins?
I would say, specially modified proteins.
Which organelle produses modified proteins?
The Golgi Apparatus modifies and packages proteins.
Is protein a phosphate ladder?
No, proteins are made of amino acid chains, some of which may be modified with attached phosphate groups.
What can proteins made on ribosomes be further modified within?
Proteins made on ribosomes can be further modified within the endoplasmic reticulum and Golgi apparatus. These organelles play a role in post-translational modifications such as glycosylation, phosphorylation, and addition of signal sequences that are important for protein function and localization within the cell.
What is the difference between proteins made from free ribosomes and proteins made from rough endoplasmic reticulum?
Proteins made from free ribosomes are typically soluble proteins that function within the cytoplasm of the cell. Proteins made from rough endoplasmic reticulum have a signal sequence that targets them to the ER for translation, allowing them to be modified and transported to other organelles or outside the cell. Proteins from the ER often have specific functions related to membrane structure or secretion.
What happens when Golgi apparatus is removed from the cell?
There would be no vesicle shipping from the cell to where modified proteins are needed. No modified proteins. There would be no lysosome synthesis either.
Where do proteins move from recticulum?
From the Endoplasmic reticulum, proteins travel to the Golgi Apparatus to be modified and packaged.
What part of a cell holds proteins?
Proteins are typically synthesized and modified in the endoplasmic reticulum (ER), a network of membrane-bound tubules and sacs. After synthesis, proteins may be further modified and packaged in the Golgi apparatus before being transported to their final destination within or outside the cell.
What would happen if Golgi was absent?
There would be no vesicle shipping from the cell to where modified proteins are needed. No modified proteins. There would be no lysosome synthesis either.
What process take place in the rough endoplasmic reticulum?
Protein synthesis, folding, and modification occur in the rough endoplasmic reticulum. Ribosomes attached to the membrane of the rough endoplasmic reticulum synthesize proteins that are then processed and modified before being transported to other parts of the cell.
