Forensic and Genetic studies

25
Q

Under the Origin of Plasma Enzymes. Enumerate the Classification of enzymes in Blood.

A

Plasma-specific enzymes
Non-plasma specific enzymes

26
Q

What organ secretes Plasma-Specific Enzyme?

27
Q

This enzyme exert their function in plasma and is also responsible in coagulation.

A

Plasma-specific enzyme.

28
Q

This enzymes has no specific functions in plasma. Thus, it lack activators or co-enzymes.

A

Non-plasma specific enzymes

29
Q

What are the two classes of Non-plasma specific enzymes

A

Enzymes of secretion
Enzymes Associated with Cellular Metabolism

30
Q

This class of Non-plasma specific enzymes is fast to disappear in plasma and is secreted in plasma in high rates.

A

Enzymes of secretion

31
Q

Under Non-plasma specific enzymes, which class is referring to this? “It carries out their functions within the cells in which they are formed”

A

Enzymes Associated with Cellular Metabolism.

32
Q

Give an example of Enzymes associated with Cellular Metabolism.

A

Creatinine Kinase (Heart muscle)

33
Q

Enumerate the classification of Enzymes based on distribution.

A

A. UNILOCULAR ENZYME
B. BILOCULAR ENZYME

34
Q

This classification of enzyme distribution based on distribution is found only in one location, particularly the cell sap.

A

Unilocular Enzyme

35
Q

This classification of enzyme distribution based on distribution is found in the mitochondria and cell sap.

A

Binocular Enzyme

36
Q

Enumerate the factors that affect binding of enzyme to substrate.

A

A. Energy
B. Molecular Compatibility
C. Space availability
D. Specifity

37
Q

Under the factors that affect binding of enzyme to substrate. This initiates the reaction.

38
Q

Under the factors that affect binding of enzyme to substrate. This talks about the commonness between the substrate and enzyme.

A

Molecular Compatibility

39
Q

Under the factors that affect binding of enzyme to substrate. This talks about the # of enzyme/substrate that can be reacted.

A

Space Availability

40
Q

Under the factors that affect binding of enzyme to substrate. This talks about the enzyme acting on specific substrate.

A

Specificity

41
Q

  2. Substrate concentration
    3 Enzyme concentration
  3. Temperature
  4. pH
  5. Activators
  6. Inhibitors
  7. Coenzyme concentration
  8. Prosthetic group
43
Q

This is the rate of enzyme action.

44
Q

Under time, what happens if the catalytic activity of an enzyme on the substrate is fast?

A

Shorter Reaction Time

45
Q

What relationship should a substrate concentration supposed to have?

A

Direct relationship

46
Q

This shows the relationship of the reaction velocity to the substrate concentration. Therefore, it will change depending on the substrate/ enzymatic concentration.

A

Michaelis-Menten Curve

47
Q

What are the phases of order kinetics?

A

First order kinetics
Zero order kinetics

48
Q

This phase of order kinetics’ enzyme concentration is FIXED. However, the substrate concentration is varied.

A

First order kinetics

49
Q

The reaction of this phase is almost directly proportional to substrate concentration at low values.

A

First Order Kinetics

50
Q

What is being affected by substrate concentration?

A

First order kinetics

51
Q

This phase is when maximum velocity is reached, the rate of increase in velocity is “0”. Also, the rate in unaffected by increased substrate concentration.

A

Zero order kinetics

52
Q

What phase is dependent on the enzyme concentration and will only change if the Enzyme concentration is increased/decreased.

A

Zero Order KInetics

53
Q

The enzyme concentration says that “An increase in enzyme concentration results to an increase in the catalytic activity” THerefore, what relationship does it have?

A

Direct relationship

54
Q

What temperature is considered to be favorable for enzyme activity?

A

30 -37’C or 37 - 40’C

55
Q

What term is used for the “favorable temp for enzyme activity”?

A

Optimum temperature

56
Q

This is the reaction rate is doubled for every 10’C increase.

57
Q
