Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
Why do cells need to make the catalase enzyme.
Catalase enzyme production is required by cells for several important reasons, the most important of which is the control of dangerous hydrogen peroxide (H2O2), which results in various cellular functions including respiration:
Detoxification: Hydrogen peroxide is a reactive oxygen species (ROS) that has the potential to be very harmful to cells. Catalase aids in cell detoxification by rapidly converting hydrogen peroxide into water (H2O) and oxygen (O2). This enzyme process avoids the formation of H2O2 and protects the cell from oxidative damage.
Protection against Oxidative Stress: In addition to hydrogen peroxide produced during cellular metabolism, cells can be exposed to external sources of ROS, such as UV light or certain compounds. Catalase is essential to neutralize these exogenous ROS, maintain the overall redox balance of the cell, and help protect against oxidative stress.
