  1. Contains intermediates for amino acid synthesis

  2. Generates fewer molecules of ATP than glycolysis

  3. Is an anaerobic process

  4. Is the major anabolic pathway for glucose synthesis

A Correct answer
Explanation

The citric acid cycle provides precursors (intermediates) for the biosynthesis of various amino acids, making it amphibolic.

Multiple choice microbiology: organisms in industry option b: biotechnology and bioinformatics biology
Study the given statements and select the correct option.
i.Carbohydrates, proteins, nucleic acids and lipids are primary metabolites.
ii.Alkaloids, flavonoids, rubber, etc., are secondary metabolites.
iii.Linoleic, linolenic and palmitic acids are the three essential fatty acids.

  1. Statements (i)and(ii) are correct

  2. Statements (i)and(iii) are incorrect

  3. Statements (i)and(iii) are correct

  4. Only statement (ii)is incorrect
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Primary metabolites are the substances that are involved in the basic metabolic processes, this includes the proteins and carbohydrates and lipids. Plant cells have different molecules other than the primary metabolite and these are considered as secondary metabolite which is not directly involved in the metabolism.

These are considered as a waste product for the plant cell this includes alkaloids, terpenoids, pigments, essential oils.
Fatty acids are obtained by the hydrolysis of fat. Linoleic acid, linolenic acid and arachnoid acid are essential fatty acids. 
Deficiency of essential fatty acid causes follicular hyperkeratosis disease.

So, the correct option is 'Statements (i)and(ii) are correct'
