Describe how a cell produces and releases proteins?

Answer 1

DNA transcribed into mRNA and then translate into proteins. Proteins moved into endoplasmic reticulum and transported to the Golgi body for further modification and package into exocytotic vacuoles. Release by exocytosis.
First,

DNA -> mRNA -> Protein

The cell produces proteins by a process called translation. mRNA is translated at the ribosome into proteins. Typically for proteins that are actively transported out of the cell, the proteins are created and inserted into the endoplasmic reticulum. The endoplasmic reticulum buds off and is processed through the Golgi apparatus where the proteins are sorted and processed. The sorting of the proteins allows the proteins that are targeted for exocytosis to be carried in vesicles to the cell membrane (by a transport protein) where they are released.

Each step involves budding, transport, and docking of vesicles which all involves use of ATP thus the process is very ATP dependent and is considered active transport.

FYI, Passive Transport can only occur DOWN a concentration gradient.

by the chromosomes and when you eat you get proteins
the cell produces proteins by the things you eat.it releases it when you use the bathroom

Answer 2

via the translation mechanism........ in which the m-RNA codes indirectly for various proteins.

and ribosomes are responsible to assemble the desired aminoacids for the specific protein for which mRNA provides the coding.

Answer 3

A protein is a series of chemicals called Amino Acids joined together in a complicated way. The information for making proteins is contained in the cell's DNA - in fact, that's all DNA is. DNA is made up of a long chain of chemical 'bases'; there are four bases: Adenine (A), Thiamine (T), Guanine (G), and Cytosine (C). These are arranged in pairs. A is always bonded to T, and G is always bonded to C. The order in which these bases come determines the 'recipe' for the protein - each group of 3 bases stands for one amino acid.

To make a protein, the DNA 'unzips' - the base pairs separate, and DNA loses its usual double helix (spiral) shape to become two straight chains. Another substance, RNA, picks up the 'recipe' for the section the cell wants, and goes to the Ribosomes, the cell parts where proteins are made (synthesized). The RNA is decoded and the protein is produced from the amino acids which you got from protein in food.

Answer 4

Protein is produced in a cell when DNA is first transcribed in the nucleus into an mRNA copy. Following various processing steps, this mRNA travels to the cytoplasm where it encounters ribosomes that scan and "read" the mRNA to produce a peptide according to the sequence encoded in the mRNA. Most protein synthesis is carried out on the rough endoplasmic reticulum.

Answer 5

Penis go boom boom
The RNA inside a cell as ribosomes is used as the formula for a protein, this is read in the nucleus, then goes to golgi apparatus

Answer 6

Cells make protein because protein are large complex molecules. The body makes up the cells that contains protein.
