Enzymes will Question 29 options: lower the free energy of a reaction raise the activation energy of a reaction raise the free energy of a reaction lower the activation energy of a reaction
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.

Enzymes are biological catalysts which speed up reactions in the human body.
They are required for various processes like metabolism, digestion, removal of toxins and for the process of DNA replication, transcription and translation.
They are specific for their substrates like a lock is specific for its key.
Free energy is the energy that is required to do work.
activation energy is the energy that is required to convert a substrate into products.
A is incorrect because enzymes do not lower down the free energy.
B is incorrect because they do not increase the activation energy.
C is incorrect because they do not increase the free energy.
D is correct because they decrease the activation energy which helps the substrate to bind to the enzyme easily. This facilitates the conversion of the substrate into products.
