Question 14

Methylmalonic acidemia

Answer 14

conversion of propionyl-CoA to succinyl-CoA

Question 15

Phenylketonuria

Answer 15

conversion of phenylalanine to tyrosine

Question 16

How does ubiquitin tag a protein?

Answer 16

Attached to the activating enzyme by hydrolyzing an ATP to AMP

ubiquitin is transferred to the conjugating enzyme

a ligase enzyme transfers the ubiquitin to the substrate

Question 17

how does the proteasome breakdown proteins

Answer 17

19S regulatory structure recognizes ubiquitinylated proteins to direct them into the 20S core

20S core has protease activity. Trypsin like
chymotrypsin like and peptidylglutamyl-peptide hydrolyzing

ATP is needed to take off the ubiquitin and breakdown the protein into amino acids
