Enzymes 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.
Why do enzymes in saliva stop working before reaching the stomach?
Enzymes in saliva, such as amylase, primarily break down starches into sugars. These enzymes get inactivated by stomach acid, as the acidic environment disrupts their structure and ability to function effectively. Therefore, their activity decreases once they reach the stomach, where the acidic pH is around 2.
What structure inside the cell holds the digestive enzymes that break down carbohydrates?
Lysosomes hold the digestive enzymes that break down the carbohydrates.
Which structure inside the cell holds the digestive enzymes that break down the carbonhydrates?
lysosomes
Why cant bacteria break down agarose?
Agarose is a complex polysaccharide that has a structure that bacteria lack the necessary enzymes to break down. Bacteria typically lack the specific enzymes required to degrade the agarose molecule effectively.
What structure inside the cell holds the digestive enzymes that break down the carbohydrates?
The lysosome is the structure inside the cell that holds the digestive enzymes responsible for breaking down carbohydrates. Lysosomes are membrane-bound organelles that function as the cell's waste disposal system, breaking down large molecules into smaller components for recycling or disposal.
What uses both acids and enzymes to break down proteins and destroy bacteria?
Villi, tiny finger shaped structure in the small intestine.
What enzymes break down gelatin?
Protease enzymes
What does mitochondria use to break down carbohydrates?
Enzymes are used to break them down. There are many enzymes
What enzymes are required for digestion?
Many sorts of enzymes at different parts of the system. In the mouth enzymes to break down sugars, in the stomach enzymes to break down proteins and in the small intestine enzymes to break down fats and sugars.
How pH levels affect enzymes?
It disrupts an enzymes shape and structure.
How do mitochondria break down nutrients?
Enzymes are used for it. There are specific enzymes
What do enzymes do in saliva?
The only enzymes I am aware of in saliva are Amylase enzymes. These enzymes break down Carbohydrates. Hope this helps!
Chemical digestion is accomplished by these proteins?
when enzymes in our bodies break down food
