Answer 1

Q1

Answer. True.

Glycogenesis means converting glucose to glycogen and gluconeogenesis means converting glucose from carbohydrate.

Q2

Answer. Mitochondria .

The oxidation of fatty acid occurs in mitochondria

Q3

Answer. Except from oxidation of alcohol because it produce aldehyde and ketone.

Q4

Answer. Water and carbondioxide

the end product of cellular respiration is water and carbondioxide. ATP are produce during the process.

Q5

Answer. All of the above are correct

phenylketouria is occurs due to deficeincy of phenylalanine hydronase leads to less production of tyrosine amino acid. This disease is common in irish people. It is mendatory for compulsory screening for newborn.
