What is biochemistry??

77julia77 [94]

Biochemistry is the study of the actions of the main metabolic processes of living organisms, which are protein synthesis (DNA and RNA molecules, genetic codes and how they work, enzyme formation and function, etc), glycolysis (cellular respiration, aka the Krebs cycle/citric acid cycle to break down glucose molecules to release chemical energy and oxydative phosphorylation, the use of that chemical energy to form ATP molecules in which the chemical energy is put in a form the cell can use, and lipid chemistry (the study of the pathways in which fatty acids are formed into lipids and fat molecules and cholestrol formation and function).
Essentially, biochemistry covers the chemical reactions necessary for cellular and organism metabolism

1. Suppose the synthesis of an amino acid was accomplished by four enzymes encoded by four genes that formed an operon. Draw a m

vivado [14]

I have attached lac operon model having 4 genes. See attachment for better understanding.

Answer:

The Lac operon is controlled by two signals.

Initiation

Glucose and lactose concentrations control the initiation of transcription of the Lac operon through their effects on the Lac repressor protein and Cap.

Lactose absent (Repression)

When lactose is absent, the Lac repressor binds the Lac operator and shuts off expression of the operon.

Lactose present (Transcription)

Addition of lactose increases the intracellular concentration of a related compound, allolactose. allolactose binds to the Lac repressor, causing it to undergo a conformational change that releases its grip on the operator DNa.

Glucose absent (Repression)

When glucose is absent, cyclic aMp (red triangle) is produced by the cell and Cap binds to DNA.

Glucose present (Transcription)

LacZ, the first gene of the operon, encodes the enzyme b-galactosidase, which breaks down lactose to galactose and glucose.
