What best describes the function of enzymes?

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.

Which best describes the function and structure of an enzyme?

Which best describes how enzymes function in the body? Enzymes are converted into products by the reactions they catalyze. One enzyme can catalyze many different reactions. They are molecules made of amino acids that speed up chemical reactions by lowering the activation energy.

Which of the following is the main function of protein?

Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.

Which statement best describes the function of enzymes Brainly?

Answer: The correct option is D. Enzymes reduce the activation energies of biological reactions.

What facilitates chemical reactions?

Enzymes are critical to the body’s healthy functioning. They assist, for example, with the breakdown of food and its conversion to energy. In fact, most of the chemical reactions in the body are facilitated by enzymes.

Why can proteins perform many functions?

Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. In every amino acid, one central carbon atom exists – the alpha-carbon (α-carbon).

What substance is most likely an enzyme?

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

What makes an enzyme a catalyst?

Like all other catalysts, enzymes are characterized by two fundamental properties. First, they increase the rate of chemical reactions without themselves being consumed or permanently altered by the reaction. Second, they increase reaction rates without altering the chemical equilibrium between reactants and products.

What is an enzyme made out of?

Like all proteins, enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function.
