Proteins that speed up chemical reactions by lowering activation energy in organisms Choose matching term square Lipids Enzymes Carbohydrates

The correct answer is Enzymes.Enzymes are proteins that act as catalysts in organisms, speeding up chemical reactions by lowering the activation energy required for the reaction to occur. They play a crucial role in various biological processes, such as digestion, metabolism, and cellular respiration.Lipids are a class of organic compounds that include fats, oils, are important for storing energy, forming cell membranes, and serving as signaling molecules.Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen atoms. They serve as a primary source of energy for organisms and are found in foods such as fruits, grains, and vegetables.Therefore, the term that matches the description of proteins that speed up chemical reactions by lowering activation energy in organisms is Enzymes.
