What controls the synthesis of enzymes in a cell?

What controls the synthesis of enzymes in a cell?

Briefly, they suggested that the rate of enzyme synthesis is under the control of regulator and operator genes, with a repressor molecule in the cell cytoplasm acting as a link between the two. There are two basic systems of control, the inducible system and the repressible system.

What organelle is responsible for enzymes?

Lysosomes
​Lysosome. 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.

What cell structure is synthesis of enzymes?

cells
Ribosomes are particularly abundant in cells that synthesize large amounts of protein. For example, the pancreas is responsible for creating several digestive enzymes and the cells that produce these enzymes contain many ribosomes.

Where are enzymes synthesized on?

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.

What is the regulation of enzyme synthesis?

In prokaryotes, genetic control of enzyme activity includes the induction or repression of enzyme synthesis by regulatory proteins that can bind to DNA and either block or enhance the function of RNA polymerase, the enzyme required for transcription.

Which organelle is primarily responsible for the synthesis of the enzymes required for energy production?

Mitochondria
Mitochondria are organelles in eukaryotic cells that produce the chemical energy necessary to support biochemical reactions.

Do lysosomes produce enzymes?

You will find organelles called lysosomes in nearly every animal-like eukaryotic cell. Lysosomes hold enzymes that were created by the cell. The purpose of the lysosome is to digest things. The Golgi then does its final work to create the digestive enzymes and pinches off a small, very specific vesicle.

Which organelle is responsible for the synthesis of proteins?

Ribosomes
Ribosomes. Ribosomes are the protein factories of the cell.

How are enzymes synthesized?

Enzymes are made from amino acids, and they are proteins. When an enzyme is formed, it is made by stringing together between 100 and 1,000 amino acids in a very specific and unique order. The chain of amino acids then folds into a unique shape.

Which cell organelle is associated with synthesis of enzymes of lysosomes?

Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label. Malfunction of lysosomal enzymes can result in lysosomal storage diseases such as Tay-Sachs disease and Pompe’s disease.
