IM: Biosynthetic Pathways

What metabolic pathway yields energy and produces energy poor-end products?

• catabolism

• anabolism

• primary metabolism

• secondary metabolism

What end-products are derived from catabolism and are also used in anabolism?

• intermediates

• secondary end products

• amphibolic intermediates

• primary and secondary end products

This metabolism is defined as the interrelated reactions associated with growth and reproduction of an organism

• trophophase
• idiophase
• catabolism
• anabolism

This metabolism is restricted only to few species, with the end-products considered as characteristic of the species

• primary

• secondary

• catabolism

• anabolism

This methods to control secondary metabolite production, is defined as factors or chemical signals which trigger secondary metabolism and morphological differentiation

• intermediates

• inducers

• strain degeneration

• plasmid control

These are factors which trigger secondary metabolism, except;

• inducers

• nutrient depletion

• decrease in growth rate

• reproduction of organism

According to this hypothesis, microorganisms produce secondary metabolites as this serves precursors to morphological changes (i.e. sporulation)

• detoxification hypothesis

• unbalanced growth hypothesis

• maintenance hypothesis

• regulatory hypothesis

In the biosynthetic pathways, what carbohydrate is usually catabolized into pyruvate

• sucrose

• starch

• glucose

• lactose

This biosynthetic pathway have no end-product and only provides a pool of phosphates for nucleotide synthesis

• EMP pathway

• PP pathway

• ED pathway

• Phosphoketolase pathway

This classification of secondary metabolite are observed in actinomycetes (ie. streptomycin and kanamycin), structure formed shows glycoside molecule attached to aglycone portion

• related to nucleosides

• derived from polyketide pathway

• derived from amino acids

• derived from intact glucose structure
