AnswersDriveCell Organelles and Functions
| A | B |
|---|---|
| Nucleus | Controls most cell processes and contain the hereditary information of DNA |
| Ribosomes | Small particles made of RNA; assemble proteins |
| Rough endoplasmic reticulum | Involved in the synthesis of proteins; has ribosomes attached to its surface |
Correspondingly, what organelles take place in protein synthesis?
Ribosomes and Endoplasmic Reticulum. Ribosomes are the organelles responsible for protein translation and are composed of ribosomal RNA (rRNA) and proteins. Some ribosomes are found in the cytoplasm, a gel-like substance that organelles float in and some are found in the rough endoplasmic reticulum.
2
Which proteins are synthesized by bound proteins?
In eukaryotic cells, it is generally accepted that protein synthesis is compartmentalized; soluble proteins are synthesized on free ribosomes, whereas secretory and membrane proteins are synthesized on endoplasmic reticulum (ER)-bound ribosomes.
3
What part of the cell collects packages and distributes proteins?
Cell Parts and Transport Flashcards/Matching
| A | B |
|---|---|
| organelles that contain digestive enzymes to breakdown waste products | lysosomes |
| organelles that make proteins | ribosomes |
| organelle in plant cells that stores water and helps support the cell structure | central vacuole |
| oganelle that packages and distributes proteins | golgi apparatus |
4
Which organelle is associated with lipid synthesis?
Membranes and their constituent proteins are assembled in the ER. This organelle contains the enzymes involved in lipid synthesis, and as lipids are manufactured in the ER, they are inserted into the organelle's own membranes. This happens in part because the lipids are too hydrophobic to dissolve into the cytoplasm.
5
What is the organelle that synthesizes proteins?
Ribosomes and Endoplasmic Reticulum. Ribosomes are the organelles responsible for protein translation and are composed of ribosomal RNA (rRNA) and proteins. Some ribosomes are found in the cytoplasm, a gel-like substance that organelles float in and some are found in the rough endoplasmic reticulum.
6
What are the organelles that are the sites of protein synthesis?
Function Of Cell Organelles
| A | B |
|---|---|
| endoplasmic reticulum | serves as a pathway for the transport of materials throughout the cell |
| nucleus | serves as the control center for cell metabolism and reproduction |
| ribosomes | site of protein synthesis |
| mitochondria | power house of cell, releases energy into the cell |
7
Where does each step of protein synthesis occur in the cell?
“protein synthesis occurs in cellular structures called ribosomes , found out-side the nucleus. The process by which genetic information is transferred from the nucleus to the ribosomes is called transcription. During transcription, a strand of ribonucleic acid (RNA) is synthesized.”
8
What part of the cell modifies and packages proteins?
a net-like structure in the cytoplasm of animal cells (especially in those cells that produce secretions), stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum. packaging products for shipping.

10
Where are the proteins synthesized inside the cell?
Originally Answered: Where are proteins synthesized inside the cell? Specifically, ribosomes are the sites of protein synthesis. Ribosomes are commonly found attached to the rough endoplasmic reticulum (RER).
11
How proteins are made in the cell?
Each protein is made up of large numbers of amino acid molecules. Each triplet of bases codes for one particular amino acid. Amino acids are made in the number and order dictated by the number and order of base triplets. Finally, the amino acid molecules join together in a long chain to make a protein molecule.
12
Do ribosomes make proteins?
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein
13
Which organelle is the site of lipid synthesis?
Rough endoplasmic reticulum.
Involved in the synthesis of proteins; has ribosomes attached to its surface.
Smooth endoplasmic reticulum.
Contain collections of enzymes that perform tasks such as the synthesis of lipids; does not have ribosomes attached to its surface.

14
Where the proteins are made?
Other ribosomes are found on the endoplasmic reticulum. Endoplasmic reticulum with attached ribosomes is called rough ER. It looks bumpy under a microscope. The attached ribosomes make proteins that will be used inside the cell and proteins made for export out of the cell.
15
Where is the site of lipid synthesis in the cell?
The ER and Golgi apparatus together constitute the endomembrane compartment in the cytoplasm of eukaryotic cells. The endomembrane compartment is a major site of lipid synthesis, and the ER is where not only lipids are synthesized, but membrane-bound proteins and secretory proteins are also made.
16
Which organelles are unique to plant cells?
Most organelles are common to both animal and plant cells. However, plant cells also have features that animal cells do not have: a cell wall, a large central vacuole, and plastids such as chloroplasts.
17
What is the site of ribosome production in a cell?
In bacterial cells, ribosomes are synthesized in the cytoplasm through the transcription of multiple ribosome gene operons. In eukaryotes, the process takes place both in the cell cytoplasm and in the nucleolus, which is a region within the cell nucleus.
18
What is the site of lipid synthesis in a cell?
Broadly speaking, there are three possible sites where lipids are synthesized: the smooth endoplasmic reticulum (SER), the cytosol and, in plants specifically, the chloroplast.
19
What is the part of the cell where proteins are made?
The function of the smooth endoplasmic reticulum is to synthesize lipids in the cell. The smooth ER also helps in the detoxification of harmful substances in the cell. Ribosomes- Organelles that help in the synthesis of proteins. Ribosomes are made up of two parts, called subunits.
