Which of the following is NOT true about enzymes? Enzymes are proteins Enzymes raise the activation energy of a chemical reaction Enzymes help a chemical reaction to occur more quickly Enzymes have an active site Enzymes may be controlled by feedback inhibition
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.
Which of the following is NOT true about enzymes?
-
Enzymes are proteins
-
Enzymes raise the activation energy of a
chemical reaction -
Enzymes help a chemical reaction to occur more quickly
-
Enzymes have an active site
-
Enzymes may be controlled by feedback inhibition
In living things, enzymes serve as catalysts that are biological molecules, usually proteins. They reduce the activation energy necessary for chemical processes to occur, facilitating and accelerating them. Enzymes are essential for metabolism, digestion, and a number of biological activities. They have specialized active sites wherein substrates can bind.
