FAQs on Enzymes & Organic Acids Video Lecture - Biology Class 12 - NEET

1. What are enzymes and organic acids?

Enzymes are proteins that act as catalysts in biological reactions, speeding up the rate of these reactions without being consumed in the process. Organic acids, on the other hand, are compounds that contain carbon and are often involved in metabolic processes in organisms.

2. How do enzymes function in the body?

Enzymes function by binding to specific molecules, called substrates, and facilitating chemical reactions. They lower the activation energy required for these reactions to occur, allowing them to happen more rapidly. Enzymes are highly specific, meaning that each enzyme can only catalyze a particular reaction.

3. What are some examples of enzymes and organic acids in everyday life?

Examples of enzymes in everyday life include amylase, which helps break down starch in the digestive system, and catalase, which breaks down hydrogen peroxide in cells. As for organic acids, citric acid is commonly found in citrus fruits like lemons and oranges, while lactic acid is produced during fermentation processes in yogurt and sourdough bread.

4. How are enzymes and organic acids important in the field of medicine?

Enzymes play a crucial role in medicine as they are often used as diagnostic tools to detect diseases. For example, elevated levels of certain enzymes in the blood can indicate liver or heart damage. Enzymes are also used in therapeutic treatments, such as enzyme replacement therapy for genetic disorders like Gaucher's disease. Organic acids, on the other hand, can be used as biomarkers to diagnose metabolic disorders.

5. Can enzymes and organic acids be harmful to the body?

In general, enzymes and organic acids are essential for normal physiological processes in the body. However, excessive levels of certain enzymes can indicate tissue damage or disease. Additionally, some organic acids, when present in high concentrations, can be toxic. For instance, accumulation of lactic acid in the muscles can lead to muscle fatigue and pain.
