Transcription of the structural genes in an inducible operon?
starts when the pathway's substrate is present
What do operons enable bacteria to do?
operon are the cluster of genes which are present to each other and having functions in realted manner as one gene is promoter which promote the function of other genes and one is operator which operates the function of structural genes whcih either synthesize certain enzyme or protein. operon can be inducible or non-inducible and negatie or positive control
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.
What would occur if the repressor of an inducible operon were mutated so it could not bind the operator?
It would result in the continuous transcription of the operon's genes.
Explain the advantage in having an inducible enzyme system that is regulated by the presence of a substrate?
It is an advantage because when the substance is present, the genes responsible for it metabolism are turned on.
What enzymes are found in the esophagus?
non
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.
What is conjugated enzymes?
When along with proteins some other non protein moiety is attached to enzymes, they are called conjugated enzymes
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
Functional and non functional plasma enzymes?
non functional enzyme
What are conjugated enzymes?
When along with proteins some other non protein moieties are momentarily attached to enzymes, these attachments are called conjugated enzymes.
what types of washing powders contain enzymes?
non-bio
Transcription of the structural genes in an inducible operon?

Synthesis of an inducible enzyme requires?
Substrate bound to a repressor Chris G.
What is the effect of phosphorylation on enzyme activity?
Phosphorylated enzymes may be more or less active than non-phosphorylated enzymes
