primary
Enzymes are considered primary metabolites because they are essential for the basic metabolic functions of an organism, such as digestion, respiration, and energy production. Secondary metabolites, on the other hand, are produced by some organisms for specific purposes like defense or signaling, but are not essential for basic metabolic processes.
A primary cell cannot be recharged whereas a secondary cell can be recharged. In a primary cell chemical reaction is irreversible whereas in a secondary cell chemical reaction is reversible. ... A primary cell is light and less expensive whereas a secondary cell is heavy and expensive.
e.g. ORGANISM BIOMASS Grass 1000 Herbivores 300 Small Carnivores 28 Large Carnivores 6 1) from producer to primary = (300/1000)x100 2) from primary to secondary = (28/300)x100 3) from secondary to carnivores = (6/28)x100 Hope this helps :)
A primary consumer obtains its energy from producers (i.e. plants). Therefore a rabbit is a primary consumer because it eats grass and other plants. A secondary consumer eats primary consumers, therefore they do not get their energy directly from plants.The fox that eats the rabbit would be a secondary consumer.
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.
primary
no penicillin is a secondary metabolite,because secondary metabolite are compounds that use to kill other bacteria eg enzymes , antibiotics.etc
Metabolites are the intermediates and products of metabolism. The term metabolite is usually restricted to small molecules. A primary metabolite is directly involved in normal growth, development, and reproduction. A secondary metabolite is not directly involved in those processes, but usually has an important ecological function that means secondary metabolite usually is not that important for the organism and if this secondary meatbolite is not present it would not harm the organism.Now the examples for ur further help primary metabolites-- enzymes certain proteins .Secondary metabolite---- antibiotics, pigments etc
pollen contain large no of primary and secondary metabolite and that metabolite are known for defence properties / mechanism therefore pollen having antimicrobial properties.
primary and secondary demand
Primary Means, it is individual there is no dependence, But Secondary will allays depends on Primary, If you want to do Secondary, you should complete primary first, There is no precondition to primary, but for Secondary Primary is the Precondition, first you should do primary, then only you are able to do secondary.
Voltage on primary/Primary turns = Voltage on secondary/Secondary turns
primary and secondary coilsAnswerPrimary and secondary windings.
Primary is IgM and secondary is IgG
secondary
Secondary
The current in the secondary when the voltage is twice the primary will be one half of the primary. The current in the primary when the voltage is twice the secondary will be twice the secondary.
