Nucleotide met

Question 1

degradation pathway

Answer 1

DNA/RNA -> denatured nucleotide -> oliconucleotide -remove PPD-> nucleotide -nucleotidase (remove P)-> nucleoside -nucleosidase (remove base) -> sugar

Question 2

Pyrimidine pathway (products)

Answer 2

FAcoa -> malonyl -> ,slonyl semialdehyde -> beta-urido.. -> dihydrouracil -> uracil -> (salvage) -> cytocine

Question 3

Pentose biosyn starter

Answer 3

hexose

Pentose syn pathwya

Answer 4

Pentose phosphorylation pathway -> PRPP -> pentose

Question 5

Pyrimidine biosyn starter

Answer 5

Glutamine

Question 6

Pyrimidine biosyn pathway

Answer 6
