✨ Key Takeaways

Enzymes are crucial for biochemical reactions and serve as indicators of tissue health.
Understanding enzyme kinetics and mechanisms is essential for accurate clinical assessments.
Isoenzymes provide specificity in diagnosing various conditions.
Measurement of enzyme activity can be influenced by multiple factors, including substrate concentration and environmental conditions.

🧠 Lessons

Specificity MattersEnzymes exhibit high specificity, which is critical for their function and for diagnostic purposes.
Kinetics KnowledgeFamiliarity with first-order and zero-order kinetics is vital for interpreting enzyme activity and understanding reaction rates.
Clinical RelevanceKnowledge of enzyme behavior in pathological conditions can aid in diagnosing diseases effectively.
Measurement TechniquesDifferent methods of measuring enzyme activity can yield varying results; understanding these methods is crucial for accurate diagnostics.

This lecture serves as a comprehensive overview of enzymes in clinical chemistry, emphasizing their importance in both biological processes and medical diagnostics.

Transcript excerpt

0:01 Hi, welcome ulit sa another lecture natin for clinical chemistry. For this video lecture, ang topic natin ay enzymes. Itong topic na to medyo may kahabaan siya pero we need to discuss every detail kasi maraming lumalabas dito na tanong. This is a perineal subject. Ito yung subject na hindi nawawalan ng question sa board exam. Okay? I hope this video will help you in your review. So simulan na natin. Okay.

0:33 For for the introduction, ang enzymes are considered as what? Biochemical catalyst. So they speed up the reaction. Again they speed up the reaction. So enzymes unlike your hormones they just catalyze the reaction no they do not actually directly uh promote changes in the tissue but they are indicators of tissue damage or degraded cells. Enzymes are protein in

1:06 nature also. That's why some autoimmune disorders are um development of auto antibody against certain enzymes. For example, in diabetes 'di ba some enzymes like glutamic tyracine phosphate no? Those are the enzymes that an individual can develop auto antibody kasi nga enzymes are protein in nature. Third, they catalyze reaction and they are very specific such
