What is the difference between the site of synthesis of lysosomal and peroxisomal proteins?
What is the difference between the site of synthesis of lysosomal and peroxisomal proteins? Lysosomal proteins are synthesised at the RER (Section 4.5); peroxisomal proteins are synthesised by free ribosomes in the cytosol (Section 4.4).
How are lysosomes and peroxisomes different?
Lysosomes contain hydrolase. This is the component or enzyme that is responsible for digestion. Peroxisomes, on the other hand, contain three oxidative enzymes such as catalase, D-amino acid oxidase, and uric acid oxidase. This is the component or enzyme that is responsible for digestion.
How are peroxisomes similar to and yet quite different from chloroplasts and mitochondria?
Peroxisomes differ from mitochondria and chloroplasts in many ways. Most notably, they are surrounded by only a single membrane, and they do not contain DNA or ribosomes. Like mitochondria and chloroplasts, however, peroxisomes are thought to acquire their proteins by selective import from the cytosol.
What are the functions of different organelles in a cell?
What’s found inside a cell
| Organelle | Function |
|---|---|
| Nucleus | DNA Storage |
| Mitochondrion | Energy production |
| Smooth Endoplasmic Reticulum (SER) | Lipid production; Detoxification |
| Rough Endoplasmic Reticulum (RER) | Protein production; in particular for export out of the cell |
What are plastids and how do they differ from each other?
What are Plastids? Plastids are double-membrane organelles which are found in the cells of plants and algae. These often contain pigments that are used in photosynthesis and different types of pigments that can change the colour of the cell.
How would you describe a key difference in the functions of lysosomes and peroxisomes?
Lysosomes and Peroxisomes both contain enzymes and are membrane bound organelles. The difference between the two are their functions, because lysosomes digest material like bacteria and also digest its dead organelles and aids in Apoptosis, while peroxisomes aid in lipid metabolism and chemical detoxification.
How do lysosomes and peroxisomes differ in structure and function?
They differ from lysosomes in the type of enzyme they hold. Peroxisomes hold on to enzymes that require oxygen (oxidative enzymes). Lysosomes have enzymes that work in oxygen-poor areas and lower pH. Peroxisomes absorb nutrients that the cell has acquired.
How would you describe a key difference in the function of lysosomes and peroxisomes?
What are the structural and functional similarities and differences between mitochondria and chloroplasts?
Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane.
Why do organelles like mitochondria and chloroplasts have their own DNA?
DNA replication and transmission to daughter organelles produces cytoplasmic inheritance of characters associated with primary events in photosynthesis and respiration. The prokaryotic ancestors of chloroplasts and mitochondria were endosymbionts whose genes became copied to the genomes of their cellular hosts.
