The immunoglobulin secreted in Bile is

1. IgG

2. 1gM

3. IgA

4. IgE

Biochemistry Answer: 3

The immunoglobulin secreted in Bile is IgA

An alpha helix of a protein is most likely to be disrupted if a missense mutation introduces the following armino acid within the alpha helical structure:

1. Alanine.
2. Aspartic acid.
3. Tyrosine.
4. Glycine.

Biochemistry Answer: 4

Glycine and proline introduce a bend in structure of protein, hence alpha helix disrupted

After fasting for 24 hours, the major source of glucose for the whole body is

1. amino acids from muscle protein degradation.

2. ketone bodies from muscle triglycerides.

3. glycogen stored in the muscle.

4. creatine phosphate

Biochemistry Answer: 4

Creatine Phosphate is the major source of glucose for the whole body during starvation

Which of the following dental tissues is most likely to be effected by Vit-A
deficiency

1. enamel

2. dentin

3. cementum

4. pulp

Biochemistry Answer: 1

Enamel most likely effected by deficiency of vitamin A

Symptoms from a riboflavin deficiency can be:

1. Cracks in the corner of the mouth (angular stomatitis)
2. Inflammation of the tongue (glossitis)
3. Eye and skin changes
4. All of the above

Biochemistry Answer: 4

The eye change include an increase in blood vessels and inflammation of the conjunctivae, cornea is invaded by capillaries, producing opaque areas and even ulceration. Dermatitis characterized by a greasy and scaly reddened lesion develops on the skin around the nasolabial folds and may extend to a butterfly shape on the cheeks. There many also be lesions at the corners (canthi) of the eyes and lobes of the mouth.

Glycine is a:
1. Glycogenic amino acid, only
2. Ketogenic only
3. Glucogenic and ketogenic
4. Since It Is optically inactive therefore none of the above

Biochemistry Answer: 1

Glycine is a Glycogenic amino acid, only

A component of the coenzyme required in a transamination process is
1. Thiamine
2 Folic acid
3 Pyridoxine
4 Riboflavin

Biochemistry Answer: 3

A component of the coenzyme required in a transamination process is Pyridoxine
