Which of the following are the primary cellular assembly sites for the production of proteins?
The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.
What is the primary cellular site for the production of ATP in animals?
The mitochondria is the cell’s primary site of ATP production accomplished through oxidative phosphorylation.
Which of the following are primary structures that package cellular secretions for export from the cell?
Module 4 Practice Lecture Quiz
| Question | Answer |
|---|---|
| Which are the sites of protein synthesis? | ribosomes |
| the primary structures for the packaging of cellular secretions for export from the cell. | Golgi bodies |
| Fluid-filled organelles that may store sugars, amino acids, toxic wastes or water in cells are called | vacuoles. |
What component of the cell is the site of polypeptide assembly?
Microtubule. This organelle is the site of polypeptide assembly.
Which of the following are the primary cellular assembly sites for the production of proteins quizlet?
The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell’s ribosomes. Following assembly, ribosomes are transported to the cell cytoplasm where they serve as the sites for protein synthesis.
What does the ribosome look like?
A ribosome itself looks like a little hamburger bun. It’s made of two subunits: a big one (the top bun) and a small one (the bottom bun). Eukaryotic ribosomes are found floating freely in the cytoplasm or attached to the rough endoplasmic reticulum (RER or rough ER for short).
What is the primary site of cellular respiration?
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
Which cellular organelle is the primary site of ATP production quizlet?
In eukaryotic cells, ATP is synthesized primarily on the inner membrane of the mitochondria.
Which cell feature is absent in bacterial cells?
Bacterial cells lack a membrane bound nucleus. Their genetic material is naked within the cytoplasm. Ribosomes are their only type of organelle. The term “nucleoid” refers to the region of the cytoplasm where chromosomal DNA is located, usually a singular, circular chromosome.
Which of the following cell organelles is responsible for the breakdown of fatty acids?
Peroxisomes
Peroxisomes are responsible for oxidation reactions that break down fatty acids and amino acids.
What are the 3 sites on a ribosome?
Each ribosomal subunit has three binding sites for tRNA: designated the A (aminoacyl) site, which accepts the incoming aminoacylated tRNA; P (peptidyl) site, which holds the tRNA with the nascent peptide chain; and E (exit) site, which holds the deacylated tRNA before it leaves the ribosome.
What is the a site of a ribosome?
The A-site (A for aminoacyl) of a ribosome is a binding site for charged t-RNA molecules during protein synthesis. One of three such binding sites, the A-site is the first location the t-RNA binds during the protein synthesis process, the other two sites being P-site (peptidyl) and E-site (exit).
