What organelle is responsible for packaging and transporting proteins?
Which organelle is used for transportation?
endoplasmic reticulum (ER)
Which organelle packages materials for secretion from the cell?
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 the powerhouse of the cell?
Why lysosomes is called suicidal bag?
Answer: Lysosomes are sphere-shaped sacs filled with hydrolytic enzymes that have the capability to break down many types of biomolecules. Lysosomes are known as suicide bags of the cell because they contain lytic enzymes capable of digesting cells and unwanted materials.
Why are ribosomes called as suicidal bags?
Answer. If the cell gets damaged, then one of the lysosomes bursts, releasing those digestive enzymes. The released enzymes then digest their own cell and ultimately the cell dies. Hence,lysosomes are called suicide bags of the cell.
What are lysosomes?
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
Why are proteins Synthesised inside the cell?
Ribosomes are produced in cytoplasm and mitochondria’s chloroplast. RNA present in ribosomes plays a significant role in the synthesis of proteins. This synthesis is called translation as the protein compound is formed from amino acid and the amino acid structure is decoded from genes.
Where are proteins Synthesised in the cell?
What are the roles of proteins in cells?
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs. They also assist with the formation of new molecules by reading the genetic information stored in DNA.
What are the three main stages of protein synthesis?
Much like the processes of DNA replication and transcription, translation consists of three main stages: initiation, elongation, and termination. Initiation takes place with the binding of a ribosome to an mRNA transcript.
What is the final product of protein synthesis?
The final product of protein synthesis is proteins. Protein synthesis starts with transcription, which occurs in the nucleus.
What are the 2 stages of protein synthesis?
Protein synthesis can be divided broadly into two phases – transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a template molecule called messenger RNA (mRNA).
