The following but one represents activators of ALP

Back (Answer)

Borate

#10
Front (Question)

Elevation in 5 nucleotidase or y glutamyltransferase together with ALP suggest that the elevated ALP is of liver not borne

Back (Answer)

True

Back (Answer)

Aldolase

#16
Front (Question)

LD

Back (Answer)

lactate dehydrogenase

#17
Front (Question)

CK

Back (Answer)

Creatine kinase

#18
Front (Question)

NAD

Back (Answer)

Nicotinamide adenine dinucleotide

#19
Front (Question)

EDTA

Back (Answer)

Ethylenediamine tetra acetic acid

#20
Front (Question)

explain why children have twise ALD activit6as that of aldult

Back (Answer)

Children need energy for cell growth and development, so aldolase provide energy to the cells

#21
Front (Question)

Which free factors would you consider any selection of enzyme for measurement in Serum for diagnostic purposes

Back (Answer)

• Distribution of enzymes in a various tissues • Knowledge of the location of Enzymes in intracellular spaces • clearance way and the late at which the enzyme activity disappears from the blood

#22
Front (Question)

Briefly describe the principle behind Hexokinase (HK) glucose 6 phosphate heterogeneous G6PD couples assay for CK analysis

Back (Answer)

1.Firstlyl creatine phosphate reacts with ATP to yield creatine and ATP in the presence of creatine kinase 2. Then ATP is reacting with glucose to produce glucose six phosphate and ATP in the presence of hexokinase 3. Glucose 6 Phosphate is reacted with NADP+ s to produce 6 phosphogluconate + NADPH + H+ in the presence of glucose 6 phosphate the dehydrogenase

#23
Front (Question)

explain 2 ways why enzymes are tools of diagnostic importance

Back (Answer)

• because they help in detecting injury of tissues that makes up the enzymes • Because they help in identifying abnormalities or absence of enzymes that may cause disease
