FranEnzymes are proteins that catalyze chemical reactions by binding to specific substrates and lowering the activation energy required for the reaction to occur. The active site of the enzyme provides a specific environment that helps to orient the substrate molecules for catalysis. The enzyme-substrate complex forms when the substrate binds to the enzyme's active site, leading to the conversion of the substrate into the product, which is then released from the enzyme.

What structure produces substance that aids in the mechanical breakdown of fats?
the liver
Does proteolytic enzymes cause denature of proteins?
Yes, proteolytic enzymes break down proteins by cleaving peptide bonds. This process may result in protein denaturation, especially if the enzyme cleaves at specific sites that disrupt the protein's structure and function.
Enzymes are proteins and can therefore be deactivated by?
Enzymes can be deactivated by changes in pH, temperature, or exposure to certain chemicals that can denature or break down the protein structure. Inhibition by specific molecules (inhibitors) can also deactivate enzymes by binding to the active site and preventing substrate binding.
What enzymes are needed to breakdown disaccharides?
The enzymes needed to break down disaccharides are sucrase (for sucrose), lactase (for lactose), and maltase (for maltose). These enzymes are required to hydrolyze the glycosidic bond holding the two sugar units together in the disaccharide.
What enzymes are responsible for the final chemical breakdown of carbohydrates and amino acids and nucleic acids?
The final breakdown of carbohydrates is facilitated by enzymes like amylase, sucrase, and maltase, which break down complex carbohydrates into simple sugars. Amino acids are broken down by enzymes like proteases and peptidases, which break proteins into individual amino acids. Nucleic acids are broken down by enzymes such as nucleases, which break down DNA and RNA into nucleotides.
