Explain the advantage in having an inducible enzyme system that is regulated by the presence of a substrate?
An inducible enzyme system allows the cell to produce enzymes only when needed in response to the presence of a specific substrate. This system is energy-efficient as it prevents the unnecessary production of enzymes when the substrate is not present. It enables the cell to quickly adapt to changes in its environment and efficiently utilize available resources.
Are all proteins enzymes Explain your answer?
No, not all proteins are enzymes. Enzymes are a type of protein that catalyze specific biochemical reactions. While many enzymes are proteins, there are also non-enzymatic proteins that serve structural, regulatory, or transport functions in the body.
Are enzymes composed mostly of proteins?
Most enzymes are protein, but not all protein are enzymes.
Transcription of the structural genes in an inducible operon?
In an inducible operon, the structural genes are transcribed only when an inducer molecule is present. The inducer molecule binds to the repressor protein, causing it to be released from the operator region. This allows the RNA polymerase to bind to the promoter region and initiate transcription of the structural genes.
What is the non-protein portion required by some enzymes for proper function?
Some enzymes do indeed have non-protein components. One really good example of this is the ribosome. Ribosomes are the enzymes responsible for translating mRNA into protein. Ribosomes are made up of both protein components and rRNA components. rRNA stands for ribosomal RNA.
Enzymes that are produced only when substrate is present are termed?
induced enzyme

What enzymes are found in the esophagus?

Definition of inducer in case of fermentation?
The majority of the enzymes used in industrial fermentation are inducible and are synthesized in response of inducers: e.g. starch for amylases, maltose for pollulanase, pectin for pectinase,olive oil and tween are also used at times.
What is the next step after a tmt was positive for inducible ischemia?
Positive for inducible ischaemia means insufficient supply of oxygen to heart. Possibility of blockages in the arteries of the heart are implied. Sometimes it can be a false positive alert. Doctor's expertise and advise is very important in Positive inducible ischaemia cases.
2 types of operons?
The two types of operons are Inducible and Repressible Operons.
Which of the following is characteristic of hexokinase (as opposed to glucokinase)?
It is not inducible by insulin
What is conjugated enzymes?
Conjugated enzymes are proteins that have a non-protein component attached to them, such as a metal ion or a coenzyme. This non-protein component is necessary for the enzyme to function properly and can help in catalyzing chemical reactions. Examples of conjugated enzymes include heme-containing enzymes like cytochrome c and flavoproteins like succinate dehydrogenase.
What are conjugated enzymes?
Conjugated enzymes are enzymes that require a non-protein component, such as a metal ion or a coenzyme, to function properly. These additional components are necessary for the enzyme to catalyze a specific reaction effectively.
what types of washing powders contain enzymes?
non-bio
Synthesis of an inducible enzyme requires?
Substrate bound to a repressor Chris G.
How does an inducible operon work including the genes and the molecules involved?
An inducible operon, such as the lac operon in E. coli, is a segment of DNA that can be turned on in response to a specific molecule, typically a substrate. In the lac operon, the presence of lactose serves as the inducer, which binds to the repressor protein, causing it to release from the operator region. This allows RNA polymerase to transcribe the structural genes (lacZ, lacY, and lacA) that encode enzymes for lactose metabolism. As a result, the operon is activated only when lactose is available, enabling the cell to efficiently utilize the sugar.
